PIC32MX1XX/2XX/5XX 64/100-PIN FAMILY
2.0 GUIDELINES FOR GETTING 
STARTED WITH 32-BIT MCUS
2.1 Basic Connection Requirements
Getting started with the PIC32MX1XX/2XX/5XX 64/
100-pin family of 32-bit Microcontrollers (MCUs) 
requires attention to a minimal set of device pin 
connections before proceeding with development. The 
following is a list of pin names, which must always be 
connected:
•All V
DD
 and V
SS
 pins (see 2.2 “Decoupling 
Capacitors”)
•All AV
DD
 and AV
SS
 pins, even if the ADC module is 
not used (see 2.2 “Decoupling Ca pac itors”)
•V
CAP
 pin (see 2.3 “Capacitor on Internal Voltage 
Regulator (V
CAP
)”) 
•MCLR pin (see 2.4 “Master Clear (MCLR) Pin”)
• PGECx/PGEDx pins, used for In-Circuit Serial 
Programming (ICSP™) and debugging purposes 
(see 2.5 “ICSP Pins”)
• OSC1 and OSC2 pins, when external oscillator 
source is used (see 2.7 “External O scilla tor Pins”)
The following pins may be required:
V
REF
+/V
REF
- pins, used when external voltage 
reference for the ADC module is implemented.
2.2 Decoupling Capacitors
The use of decoupling capacitors on power supply 
pins, such as V
DD
, V
SS
, AV
DD
 and AV
SS
 is required. 
See Figure 2-1.
Consider the following criteria when using decoupling 
capacitors:
•Value and type of capacitor: A value of 0.1 µF 
(100 nF), 10-20V is recommended. The capacitor 
should be a low Equivalent Series Resistance 
(low-ESR) capacitor and have resonance 
frequency in the range of 20 MHz and higher. It is 
further recommended that ceramic capacitors be 
used.
•Placement on the printed circuit board: The 
decoupling capacitors should be placed as close 
to the pins as possible. It is recommended that 
the capacitors be placed on the same side of the 
board as the device. If space is constricted, the 
capacitor can be placed on another layer on the 
PCB using a via; however, ensure that the trace 
length from the pin to the capacitor is within one-
quarter inch (6 mm) in length.
•Handling hi gh frequency nois e: If the board is 
experiencing high frequency noise, upward of 
tens of MHz, add a second ceramic-type capacitor 
in parallel to the above described decoupling 
capacitor. The value of the second capacitor can 
be in the range of 0.01 µF to 0.001 µF. Place this 
second capacitor next to the primary decoupling 
capacitor. In high-speed circuit designs, consider 
implementing a decade pair of capacitances as 
close to the power and ground pins as possible. 
For example, 0.1 µF in parallel with 0.001 µF.
•Maximiz ing perform anc e: On the board layout 
from the power supply circuit, run the power and 
return traces to the decoupling capacitors first, 
and then to the device pins. This ensures that the 
decoupling capacitors are first in the power chain. 
Equally important is to keep the trace length 
between the capacitor and the power pins to a 
minimum thereby reducing PCB track inductance.
Note: This data sheet summarizes the features 
of the PIC32MX1XX/2XX/5XX 64/100-pin 
family of devices. It is not intended to be a 
comprehensive reference source. To 
complement the information in this data 
sheet, refer to the related section of the 
“PI C32 Fa mily R efere nce Ma nual” , which 
is available from the Microchip web site 
(www.microchip.com/PIC32).
Note: The AV
DD
 and AV
SS
 pins must be 
connected, regardless of ADC use and 
the ADC voltage reference source.

2.2.1 BULK CAPACITORS

The use of a bulk capacitor is recommended to improve

power supply stability. Typical values range from 4.7 µF

to 47 µF. This capacitor should be located as close to

the device as possible.

2.3 Capacit or on Internal Voltage

Regulator (V

CAP

)

2.3.1 INTERNAL REGULATOR MODE

A low-ESR (3 ohm) capacitor is required on the V

CAP

pin, which is used to stabilize the internal voltage regu-

lator output. The V

CAP

pin must not be connected to

, and must have a C

EFC

capacitor, with at least a

6V rating, connected to ground. The type can be

ceramic or tantalum. Refer to Section 31.0 “40 MHz

Electrical Characteristics” for additional information

on C

EFC

specifications.

2.4 Master Clear (MCLR) Pin

The MCLR pin provides two specific device

functions:

• Device Reset

• Device programming and debugging

Pulling The MCLR pin low generates a device Reset.

Figure 2-2 illustrates a typical MCLR circuit. During

device programming and debugging, the resistance

and capacitance that can be added to the pin must

be considered. Device programmers and debuggers

drive the MCLR pin. Consequently, specific voltage

levels (V

and V

) and fast signal transitions must

not be adversely affected. Therefore, specific values

of R and C will need to be adjusted based on the

application and PCB requirements.

For example, as illustrated in Figure 2-2, it is

recommended that the capacitor C, be isolated from

the MCLR pin during programming and debugging

operations.

Place the components illustrated in Figure 2-2 within

one-quarter inch (6 mm) from the MCLR pin.

2.5 ICSP Pins

The PGECx and PGEDx pins are used for In-Circuit

Serial Programming™ (ICSP™) and debugging pur-

poses. It is recommended to keep the trace length

between the ICSP connector and the ICSP pins on the

device as short as possible. If the ICSP connector is

expected to experience an ESD event, a series resistor

is recommended, with the value in the range of a few

tens of Ohms, not to exceed 100 Ohms.

Pull-up resistors, series diodes and capacitors on the

PGECx and PGEDx pins are not recommended as they

will interfere with the programmer/debugger communi-

cations to the device. If such discrete components are

an application requirement, they should be removed

from the circuit during programming and debugging.

Alternatively, refer to the AC/DC characteristics and

timing requirements information in the respective

device Flash programming specification for information

on capacitive loading limits and pin input voltage high

) and input voltage low (V

) requirements.

Ensure that the “Communication Channel Select” (i.e.,

PGECx/PGEDx pins) programmed into the device

matches the physical connections for the ICSP to

MPLAB

ICD 3 or MPLAB REAL ICE™.

For more information on MPLAB ICD 3 and MPLAB

REAL ICE connection requirements, refer to the follow-

ing documents that are available on the Microchip web

site.

2.6 JTAG

The TMS, TDO, TDI and TCK pins are used for testing

and debugging according to the Joint Test Action

Group (JTAG) standard. It is recommended to keep the

trace length between the JTAG connector and the

JTAG pins on the device as short as possible. If the

JTAG connector is expected to experience an ESD

event, a series resistor is recommended, with the value

in the range of a few tens of Ohms, not to exceed 100

Ohms.

Pull-up resistors, series diodes and capacitors on the

TMS, TDO, TDI and TCK pins are not recommended

as they will interfere with the programmer or debugger

communications to the device. If such discrete

components are an application requirement, they

should be removed from the circuit during

programming and debugging. Alternatively, refer to the

AC/DC characteristics and timing requirements

information in the respective device Flash

programming specification for information on

capacitive loading limits and pin input voltage high (V

)

and input voltage low (V

) requirements

2.7 External Oscillator Pins

Many MCUs have options for at least two oscillators: a

high-frequency primary oscillator and a low-frequency

secondary oscillator (refer to Section 8.0 “Oscillator

Configuration” for details).

The oscillator circuit should be placed on the same side

of the board as the device. Also, place the oscillator cir-

cuit close to the respective oscillator pins, not exceed-

ing one-half inch (12 mm) distance between them. The

load capacitors should be placed next to the oscillator,

on the same side of the board. Use a grounded copper

pour around the oscillator circuit to isolate them from

surrounding circuits. The grounded copper pour should

be routed directly to the MCU ground. Do not run any

signal traces or power traces inside the ground pour.

Also, if using a two-sided board, avoid any traces on

the other side of the board where the crystal is placed.

A suggested layout is illustrated in Figure 2-3.

2.7.1 CRYSTAL OSCILLATOR DESIGN

CONSIDERATION

The following examples are used to calculate the

Primary Oscillator loading capacitor values:

•C

= PIC32_OSC2_Pin Capacitance = ~4-5 pF

•C

OUT

= PIC32_OSC1_Pin Capacitance = ~4-5 pF

• C1 and C2 = XTAL manufacturing recommended

loading capacitance

• Estimated PCB stray capacitance, (i.e.,12 mm

length) = 2.5 pF

EXAMPLE 2-1: CRYSTAL LOAD CAPAC ITOR

CALCULATION

The following tips are used to increase oscillator gain,

(i.e., to increase peak-to-peak oscillator signal):

• Select a crystal with a lower “minimum” power drive

rating

• Select an crystal oscillator with a lower XTAL

manufacturing “ESR” rating.

• Add a parallel resistor across the crystal. The smaller

the resistor value the greater the gain. It is recom-

mended to stay in the range of 600k to 1M

• C1 and C2 values also affect the gain of the oscillator.

The lower the values, the higher the gain.

• C2/C1 ratio also affects gain. To increase the gain,

make C1 slightly smaller than C2, which will also help

start-up performance.

FIGURE 2-4: PRIMARY CRYSTAL

OSCILLATOR CIRCUIT

RECOMMENDATIONS

Note: Do not add excessive gain such that the

oscillator signal is clipped, flat on top of

the sine wave. If so, you need to reduce

the gain or add a series resistor, RS, as

shown in circuit “C” in Figure 2-4. Failure

to do so will stress and age the crystal,

which can result in an early failure. Adjust

the gain to trim the max peak-to-peak to

-0.6V. When measuring the oscilla-

tor signal you must use a FET scope

probe or a probe with  1.5 pF or the

scope probe itself will unduly change the

gain and peak-to-peak levels.

= 10 + 2.5 = 12.5

2.8 Unused I/Os

Unused I/O pins should not be allowed to float as

inputs. They can be configured as outputs and driven

to a logic-low state.

Alternatively, inputs can be reserved by connecting the

pin to V

through a 1k to 10k resistor and configuring

the pin as an input.

2.9 Considerations When Interfacing

to Remotely Powered Circuits

2.9.1 NON-5V TOLERANT INPUT PINS

A quick review of the absolute maximum rating section

in 31.0 “40 MHz Elect rical Charac teris tics” will indi-

cate that the voltage on any non-5v tolerant pin may not

exceed AV

+ 0.3V. Figure 2-5 shows an exam-

ple of a remote circuit using an independent power

source, which is powered while connected to a PIC32

Without proper signal isolation, on non-5V tolerant

pins, the remote signal can power the PIC32 device

through the high side ESD protection diodes.

Besides violating the absolute maximum rating

specification when V

of the PIC32 device is

restored and ramping up or ramping down, it can

also negatively affect the internal Power-on Reset

(POR) and Brown-out Reset (BOR) circuits, which

can lead to improper initialization of internal PIC32

logic circuits. In these cases, it is recommended to

implement digital or analog signal isolation as

depicted in Figure 2-6, as appropriate. This is

indicative of all industry microcontrollers and not just

Microchip products.

2.9.2 5V TOLERANT INPUT PINS

The internal high side diode on 5V tolerant pins are

bussed to an internal floating node, rather than being

connected to V

, as shown in Figure 2-7. Voltages

on these pins, if V

< 2.3V, should not exceed

roughly 3.2V relative to V

of the PIC32 device.

Voltage of 3.6V or higher will violate the absolute

maximum specification, and will stress the oxide

layer separating the high side floating node, which

impacts device reliability. If a remotely powered

“digital-only” signal can be guaranteed to always be

 3.2V relative to Vss on the PIC32 device side, a

5V tolerant pin could be used without the need for a

digital isolator. This is assuming there is not a

ground loop issue, logic ground of the two circuits

not at the same absolute level, and a remote logic

low input is not less than V

- 0.3V.

3.2 Architectur e Overview

The MIPS32

M4K

processor core contains several

logic blocks working together in parallel, providing an

efficient high-performance computing engine. The

following blocks are included with the core:

• Execution Unit

• Multiply/Divide Unit (MDU)

• System Control Coprocessor (CP0)

• Fixed Mapping Translation (FMT)

• Dual Internal Bus interfaces

• Power Management

• MIPS16e

Support

• Enhanced JTAG (EJTAG) Controller

3.2.1 EXECUTION UNIT

The MIPS32

M4K

processor core execution unit

implements a load/store architecture with single-cycle

ALU operations (logical, shift, add, subtract) and an

autonomous multiply/divide unit. The core contains

thirty-two 32-bit General Purpose Registers (GPRs)

used for integer operations and address calculation.

The execution unit includes:

• 32-bit adder used for calculating the data address

• Address unit for calculating the next instruction

address

• Logic for branch determination and branch target

address calculation

• Load aligner

• Bypass multiplexers used to avoid stalls when

executing instruction streams where data

producing instructions are followed closely by

consumers of their results

• Leading Zero/One detect unit for implementing

the CLZ and CLO instructions

• Arithmetic Logic Unit (ALU) for performing bitwise

logical operations

• Shifter and store aligner

3.2.2 MULTIPLY/DIVIDE UNIT (MDU)

The MIPS32

M4K

processor core includes a Multi-

ply/Divide Unit (MDU) that contains a separate pipeline

for multiply and divide operations. This pipeline oper-

ates in parallel with the Integer Unit (IU) pipeline and

does not stall when the IU pipeline stalls. This allows

MDU operations to be partially masked by system stalls

and/or other integer unit instructions.

The high-performance MDU consists of a 32x16 booth

recoded multiplier, result/accumulation registers (HI

and LO), a divide state machine, and the necessary

multiplexers and control logic. The first number shown

(‘32’ of 32x16) represents the rs operand. The second

number (‘16’ of 32x16) represents the rt operand. The

PIC32 core only checks the value of the latter (rt) oper-

and to determine how many times the operation must

pass through the multiplier. The 16x16 and 32x16

operations pass through the multiplier once. A 32x32

operation passes through the multiplier twice.

The MDU supports execution of one 16x16 or 32x16

multiply operation every clock cycle; 32x32 multiply

operations can be issued every other clock cycle.

Appropriate interlocks are implemented to stall the

issuance of back-to-back 32x32 multiply operations.

The multiply operand size is automatically determined

by logic built into the MDU.

Divide operations are implemented with a simple 1 bit

per clock iterative algorithm. An early-in detection

checks the sign extension of the dividend (rs) operand.

If rs is 8 bits wide, 23 iterations are skipped. For a 16-bit

wide rs, 15 iterations are skipped and for a 24-bit wide

rs, 7 iterations are skipped. Any attempt to issue a sub-

sequent MDU instruction while a divide is still active

causes an IU pipeline stall until the divide operation is

completed.

Table 3-1 lists the repeat rate (peak issue rate of cycles

until the operation can be reissued) and latency (num-

ber of cycles until a result is available) for the PIC32

core multiply and divide instructions. The approximate

latency and repeat rates are listed in terms of pipeline

clocks.

PIC32MX1XX/2XX/5XX 64/100-PIN FAMILY

The MIPS architecture defines that the result of a

multiply or divide operation be placed in the HI and LO

registers. Using the Move-From-HI (MFHI) and Move-

From-LO (MFLO) instructions, these values can be

transferred to the General Purpose Register file.

In addition to the HI/LO targeted operations, the

MIPS32

architecture also defines a multiply instruction,

MUL, which places the least significant results in the pri-

mary register file instead of the HI/LO register pair. By

avoiding the explicit MFLO instruction required when

using the LO register, and by supporting multiple desti-

nation registers, the throughput of multiply-intensive

operations is increased.

Two other instructions, Multiply-Add (MADD) and

Multiply-Subtract (MSUB), are used to perform the

multiply-accumulate and multiply-subtract operations.

The MADD instruction multiplies two numbers and then

adds the product to the current contents of the HI and

LO registers. Similarly, the MSUB instruction multiplies

two operands and then subtracts the product from the

HI and LO registers. The MADD and MSUB operations

are commonly used in DSP algorithms.

3.2.3 SYSTEM CONTROL 

COPROCESSOR (CP0)

In the MIPS architecture, CP0 is responsible for the

virtual-to-physical address translation, the exception

control system, the processor’s diagnostics capability,

the operating modes (Kernel, User and Debug) and

whether interrupts are enabled or disabled. Configura-

tion information, such as presence of options like

MIPS16e

, is also available by accessing the CP0

registers, listed in Tabl e 3-2.

3.3 Power Management

The MIPS

M4K

processor core offers a number of

power management features, including low-power

design, active power management and power-down

modes of operation. The core is a static design that

supports slowing or Halting the clocks, which reduces

system power consumption during Idle periods.

3.3.1 INSTRUCTION-CONTROLLED

POWER MANAGEMENT

The mechanism for invoking Power-Down mode is

through execution of the WAIT instruction. For more

information on power management, see Section 27.0

“Power-Saving Fea tures ”.

3.3.2 LOCAL CLOCK GATING

The majority of the power consumed by the PIC32MX-

1XX/2XX/5XX 64/100-pin family core is in the clock

tree and clocking registers. The PIC32MX family uses

extensive use of local gated-clocks to reduce this

dynamic power consumption.

3.4 EJTAG Debug Support

The MIPS

M4K

processor core provides for an

Enhanced JTAG (EJTAG) interface for use in the soft-

ware debug of application and kernel code. In addition

to standard User mode and Kernel modes of operation,

the M4K

core provides a Debug mode that is entered

after a debug exception (derived from a hardware

breakpoint, single-step exception, etc.) is taken and

continues until a Debug Exception Return (DERET)

instruction is executed. During this time, the processor

executes the debug exception handler routine.

The EJTAG interface operates through the Test Access

Port (TAP), a serial communication port used for trans-

ferring test data in and out of the core. In addition to the

standard JTAG instructions, special instructions

defined in the EJTAG specification define which

registers are selected and how they are used.

4.0 MEMORY ORGANIZATION

PIC32MX1XX/2XX/5XX 64/100-pin microcontrollers

provide 4 GB of unified virtual memory address space.

All memory regions, including program, data memory,

SFRs and Configuration registers, reside in this

address space at their respective unique addresses.

The program and data memories can be optionally par-

titioned into user and kernel memories. In addition, the

data memory can be made executable, allowing

PIC32MX1XX/2XX/5XX 64/100-pin devices to execute

from data memory.

The key features include:

• 32-bit native data width

• Separate User (KUSEG) and Kernel (KSEG0/

KSEG1) mode address space

• Flexible program Flash memory partitioning

• Flexible data RAM partitioning for data and

program space

• Separate boot Flash memory for protected code

• Robust bus exception handling to intercept 

runaway code

• Simple memory mapping with Fixed Mapping

Translation (FMT) unit

4.1 Memory Layout

PIC32MX1XX/2XX/5XX 64/100-pin microcontrollers

implement two address schemes: virtual and physical.

All hardware resources, such as program memory,

data memory and peripherals, are located at their

respective physical addresses. Virtual addresses are

exclusively used by the CPU to fetch and execute

instructions as well as access peripherals. Physical

addresses are used by bus master peripherals, such as

DMA and the Flash controller, that access memory

independently of the CPU.

The memory maps for the PIC32MX1XX/2XX/5XX 64/

100-pin devices are illustrated in Figure 4-1 through

Figure 4-4.

5.0 INTERRUPT CONTROLLER

PIC32MX1XX/2XX/5XX 64/100-pin devices generate

interrupt requests in response to interrupt events from

peripheral modules. The interrupt control module exists

externally to the CPU logic and prioritizes the interrupt

events before presenting them to the CPU.

The PIC32MX1XX/2XX/5XX 64/100-pin interrupt

module includes the following features:

• Up to 76 interrupt sources

• Up to 46 interrupt vectors

• Single and multi-vector mode operations

• Five external interrupts with edge polarity control

• Interrupt proximity timer

• Seven user-selectable priority levels for each

vector

• Four user-selectable subpriority levels within each

priority

• Software can generate any interrupt

• User-configurable interrupt vector table location

• User-configurable interrupt vector spacing

6.0 FLASH PROGRAM MEMORY

PIC32MX1XX/2XX/5XX 64/100-pin devices contain an

internal Flash program memory for executing user

code. There are three methods by which the user can

program this memory:

• Run-Time Self-Programming (RTSP)

• EJTAG Programming

• In-Circuit Serial Programming™ (ICSP™)

RTSP is performed by software executing from either

Flash or RAM memory. Information about RTSP

techniques is available in Section 5. “Flash Program

Memory” (DS60001121) in the “PIC32 Family

Reference Manual”.

EJTAG is performed using the EJTAG port of the

device and an EJTAG capable programmer.

ICSP is performed using a serial data connection to the

device and allows much faster programming times than

RTSP.

The EJTAG and ICSP methods are described in the

“PIC32 Flash Programming Specification”

(DS60001145), which can be downloaded from the

Microchip web site.

Note: This data sheet summarizes the features

of the PIC32MX1XX/2XX/5XX 64/100-pin

family of devices. It is not intended to be

a comprehensive reference source. To

complement the information in this data

sheet, refer to Section 5. “Flash

Program Memory” (DS60001121) in the

“PI C32 Fami ly Re ferenc e Manua l” , which

is available from the Microchip web site

(www.microchip.com/PIC32).

Note: On PIC32MX1XX/2XX/5XX 64/100-pin

devices, the Flash page size is 1 KB and

the row size is 128 bytes (256 IW and

32 IW, respectively).

8.0 OSCILLATOR

CONFIGURATION

The PIC32MX1XX/2XX/5XX 64/100-pin oscillator

system has the following modules and features:

• A Total of four external and internal oscillator

options as clock sources

• On-Chip PLL with user-selectable input divider,

multiplier and output divider to boost operating

frequency on select internal and external

oscillator sources

• On-Chip user-selectable divisor postscaler on

select oscillator sources

• Software-controllable switching between 

various clock sources

• A Fail-Safe Clock Monitor (FSCM) that detects

clock failure and permits safe application recovery

or shutdown

• Dedicated On-Chip PLL for USB peripheral

A block diagram of the oscillator system is provided in

Figure 8-1.

9.0 DIRECT MEMORY ACCESS

(DMA) CONTROLLER

The PIC32 Direct Memory Access (DMA) controller is a

bus master module useful for data transfers between

different devices without CPU intervention. The source

and destination of a DMA transfer can be any of the

memory mapped modules existent in the PIC32 (such

as Peripheral Bus (PBUS) devices: SPI, UART, PMP,

etc.) or memory itself.

The following are some of the key features of the DMA

controller module:

• Four identical channels, each featuring:

- Auto-increment source and destination

address registers

- Source and destination pointers

- Memory to memory and memory to

peripheral transfers

• Automatic word-size detection:

- Transfer granularity, down to byte level

- Bytes need not be word-aligned at source

and destination

• Fixed priority channel arbitration

• Flexible DMA channel operating modes:

- Manual (software) or automatic (interrupt)

DMA requests

- One-Shot or Auto-Repeat Block Transfer

modes

- Channel-to-channel chaining

• Flexible DMA requests:

- A DMA request can be selected from any of

the peripheral interrupt sources

- Each channel can select any (appropriate)

observable interrupt as its DMA request

source

- A DMA transfer abort can be selected from

any of the peripheral interrupt sources

- Pattern (data) match transfer termination

• Multiple DMA channel status interrupts:

- DMA channel block transfer complete

- Source empty or half empty

- Destination full or half full

- DMA transfer aborted due to an external

event

- Invalid DMA address generated

• DMA debug support features:

- Most recent address accessed by a DMA

channel

- Most recent DMA channel to transfer data

• CRC Generation module:

- CRC module can be assigned to any of the

available channels

- CRC module is highly configurable

bit 31-0 DCRCDATA<31:0>: CRC Data Register bits

Writing to this register will seed the CRC generator. Reading from this register will return the current value of

the CRC. Bits greater than PLEN will return ‘0’ on any read.

When CRCTYP (DCRCCON<15>) = 1 (CRC module is in IP Header mode):

Only the lower 16 bits contain IP header checksum information. The upper 16 bits are always ‘0’. Data written

to this register is converted and read back in 1’s complement form (i.e., current IP header checksum value).

When CRCTYP (DCRCCON<15>) = 0 (CRC module is in LFSR mode):

Bits greater than PLEN will return ‘0’ on any read.

Note 1: The chain selection bit takes effect when chaining is enabled (i.e., CHCHN = 1).

2: When the channel is suspended by clearing this bit, the user application should poll the CHBUSY bit (if

available on the device variant) to see when the channel is suspended, as it may take some clock cycles

to complete a current transaction before the channel is suspended.

10.0 USB ON-THE-GO (OTG)

The Universal Serial Bus (USB) module contains

analog and digital components to provide a USB 2.0

full-speed and low-speed embedded host, full-speed

device or OTG implementation with a minimum of

external components. This module in Host mode is

intended for use as an embedded host and therefore

does not implement a UHCI or OHCI controller.

The USB module consists of the clock generator, the

USB voltage comparators, the transceiver, the Serial

Interface Engine (SIE), a dedicated USB DMA control-

ler, pull-up and pull-down resistors, and the register

interface. A block diagram of the PIC32 USB OTG

module is presented in Figure 10-1.

The clock generator provides the 48 MHz clock

required for USB full-speed and low-speed communi-

cation. The voltage comparators monitor the voltage on

the V

BUS

pin to determine the state of the bus. The

transceiver provides the analog translation between

the USB bus and the digital logic. The SIE is a state

machine that transfers data to and from the endpoint

buffers and generates the hardware protocol for data

transfers. The USB DMA controller transfers data

between the data buffers in RAM and the SIE. The inte-

grated pull-up and pull-down resistors eliminate the

need for external signaling components. The register

interface allows the CPU to configure and

communicate with the module.

The PIC32 USB module includes the following

features:

• USB Full-speed support for host and device

• Low-speed host support

• USB OTG support

• Integrated signaling resistors

• Integrated analog comparators for V

BUS

monitoring

• Integrated USB transceiver

• Transaction handshaking performed by hardware

• Endpoint buffering anywhere in system RAM

• Integrated DMA to access system RAM and Flash

of the PIC32MX1XX/2XX/5XX 64/100-pin

family of devices. It is not intended to be

11.0 I/O PORTS

General purpose I/O pins are the simplest of peripher-

als. They allow the PIC

MCU to monitor and control

other devices. To add flexibility and functionality, some

pins are multiplexed with alternate functions. These

functions depend on which peripheral features are on

the device. In general, when a peripheral is functioning,

that pin may not be used as a general purpose I/O pin.

The following are the key features of this module:

• Individual output pin open-drain enable or disable

• Individual input pin weak pull-up and pull-down

• Monitor selective inputs and generate interrupt

when change in pin state is detected

• Operation during CPU Sleep and Idle modes

• Fast bit manipulation using CLR, SET and INV

registers

Figure 11-1 illustrates a block diagram of a typical

multiplexed I/O port.

11 .1 Pa ra llel I/ O (P IO) Po rt s

All port pins have ten registers directly associated with

their operation as digital I/O. The data direction register

(TRISx) determines whether the pin is an input or an

output. If the data direction bit is a ‘1’, then the pin is an

input. All port pins are defined as inputs after a Reset.

Reads from the latch (LATx) read the latch. Writes to

the latch write the latch. Reads from the port (PORTx)

read the port pins, while writes to the port pins write the

latch.

11.1.1 OPEN-DRAIN CONFIGURATION

In addition to the PORTx, LATx, and TRISx registers for

data control, some port pins can also be individually

configured for either digital or open-drain output. This is

controlled by the Open-Drain Control register, ODCx,

associated with each port. Setting any of the bits

configures the corresponding pin, regardless of the out-

put function including PPS remapped output functions

to act as an open-drain output. The only exception is

the I

C pins that are open drain by default.

The open-drain feature allows the presence of outputs

higher than V

(e.g., 5V) on any desired 5V-tolerant

pins by using external pull-up resistors. The maximum

open-drain voltage allowed is the same as the

maximum V

specification.

See the “Device Pin Tables” section for the available

pins and their functionality.

11.1.2 CONFIGURING ANALOG AND

DIGITAL PORT PINS

The ANSELx register controls the operation of the

analog port pins. The port pins that are to function as

analog inputs must have their corresponding ANSEL

and TRIS bits set. In order to use port pins for I/O

functionality with digital modules, such as Timers,

UARTs, etc., the corresponding ANSELx bit must be

cleared.

The ANSELx register has a default value of 0xFFFF;

therefore, all pins that share analog functions are

analog (not digital) by default. The ANSELx register bit,

when cleared, disables the corresponding digital input

buffer pin(s).

If the TRIS bit is cleared (output) while the ANSELx bit

is set, the digital output level (V

or V

) is converted

by an analog peripheral, such as the ADC module or

Comparator module. The TRISx bits only control the

corresponding digital output buffer pin(s).

When the PORT register is read, all pins configured as

analog input channels are read as cleared (a low level;

i.e., when ANSELx = 1; TRISx = x).

Analog levels on any pin defined as a digital input

(including the ANx pins) can cause the input buffer to

consume current that exceeds the device

specifications.

11.1.3 I/O PORT WRITE/READ TIMING

One instruction cycle is required between a port

direction change or port write operation and a read

operation of the same port. Typically, this instruction

would be an NOP.

11.1.4 INPUT CHANGE NOTIFICATION

The input Change Notification (CN) function of the I/O

ports allows the PIC32MX1XX/2XX/5XX 64/100-pin

devices to generate interrupt requests to the processor

in response to a change-of-state on selected input pins.

This feature can detect input change-of-states even in

Sleep mode, when the clocks are disabled. Every I/O

port pin can be selected (enabled) for generating an

interrupt request on a change-of-state.

Five control registers are associated with the CN func-

tionality of each I/O port. The CNENx registers contain

the CN interrupt enable control bits for each of the input

pins. Setting any of these bits enables a CN interrupt

for the corresponding pins.

The CNSTATx register indicates whether a change

occurred on the corresponding pin since the last read

of the PORTx bit.

11.1.5 INTERNALLY SELECTABLE PULL-

UPS AND PULL-DOWNS

Each I/O pin also has a weak pull-up and every I/O

pin has a weak pull-down connected to it, which are

independent of any other I/O pin functionality (i.e.,

PPS, Open Drain, or CN). The pull-ups act as a

current source or sink source connected to the pin,

and eliminate the need for external resistors when

push-button or keypad devices are connected. The

pull-ups and pull-downs are enabled separately using

the CNPUx and the CNPDx registers, which contain

the control bits for each of the pins. Setting any of the

control bits enables the weak pull-ups and/or pull-

downs for the corresponding pins.

An additional control register (CNCONx) is shown in

11 .2 CL R , SE T, a n d INV Reg is ters

Every I/O module register has a corresponding CLR

(clear), SET (set) and INV (invert) register designed to

provide fast atomic bit manipulations. As the name of

the register implies, a value written to a SET, CLR or

INV register effectively performs the implied operation,

but only on the corresponding base register and only

bits specified as ‘1’ are modified. Bits specified as ‘0’

are not modified.

Reading SET, CLR and INV registers returns undefined

values. To see the affects of a write operation to a SET,

CLR or INV register, the base register must be read.

Note: Pull-ups and pull-downs on change notifi-

cation pins should always be disabled

when the port pin is configured as a digital

output. They should also be disabled on

5V tolerant pins when the pin voltage can

exceed V

11.3 Peripheral Pin Select

A major challenge in general purpose devices is provid-

ing the largest possible set of peripheral features while

minimizing the conflict of features on I/O pins. The chal-

lenge is even greater on low pin count devices. In an

application where more than one peripheral needs to

be assigned to a single pin, inconvenient workarounds

in application code or a complete redesign may be the

only options.

Peripheral pin select configuration provides an

alternative to these choices by enabling peripheral set

selection and their placement on a wide range of I/O

pins. By increasing the pinout options available on a

particular device, users can better tailor the device to

their entire application, rather than trimming the

application to fit the device.

The peripheral pin select configuration feature

operates over a fixed subset of digital I/O pins. Users

may independently map the input and/or output of most

digital peripherals to these I/O pins. Peripheral pin

select is performed in software and generally does not

require the device to be reprogrammed. Hardware

safeguards are included that prevent accidental or

spurious changes to the peripheral mapping once it has

been established.

11.3.1 AVAILABLE PINS

The number of available pins is dependent on the

particular device and its pin count. Pins that support the

peripheral pin select feature include the designation

“RPn” in their full pin designation, where “RP”

designates a remappable peripheral and “n” is the

remappable port number.

11.3.2 AVAILABLE PERIPHERALS

The peripherals managed by the peripheral pin select

are all digital-only peripherals. These include general

serial communications (UART and SPI), general pur-

pose timer clock inputs, timer-related peripherals (input

capture and output compare) and interrupt-on-change

inputs.

In comparison, some digital-only peripheral modules

are never included in the peripheral pin select feature.

This is because the peripheral’s function requires spe-

cial I/O circuitry on a specific port and cannot be easily

connected to multiple pins. These modules include I

among others. A similar requirement excludes all mod-

ules with analog inputs, such as the Analog-to-Digital

Converter (ADC).

A key difference between remappable and non-remap-

pable peripherals is that remappable peripherals are

not associated with a default I/O pin. The peripheral

must always be assigned to a specific I/O pin before it

can be used. In contrast, non-remappable peripherals

are always available on a default pin, assuming that the

peripheral is active and not conflicting with another

peripheral.

When a remappable peripheral is active on a given I/O

pin, it takes priority over all other digital I/O and digital

communication peripherals associated with the pin.

Priority is given regardless of the type of peripheral that

is mapped. Remappable peripherals never take priority

over any analog functions associated with the pin.

11.3.3 CONTROLLING PERIPHERAL PIN

SELECT

Peripheral pin select features are controlled through

two sets of SFRs: one to map peripheral inputs, and

one to map outputs. Because they are separately

controlled, a particular peripheral’s input and output (if

the peripheral has both) can be placed on any

selectable function pin without constraint.

The association of a peripheral to a peripheral-select-

able pin is handled in two different ways, depending on

whether an input or output is being mapped.

11.3.4 INPUT MAPPING

The inputs of the peripheral pin select options are

mapped on the basis of the peripheral. That is, a control

will be mapped to. The [pin name]R registers, where [pin

name] refers to the peripheral pins listed in Ta b le 11-1,

are used to configure peripheral input mapping (see

fields. Programming these bit fields with an appropriate

value maps the RPn pin with the corresponding value to

that peripheral. For any given device, the valid range of

values for any bit field is shown in Table 11-1.

For example, Figure 11-2 illustrates the remappable

pin selection for the U1RX input.

FIGURE 11-2: REMAPPABLE INPUT

EXAMPLE FOR U1RX

RPA2

RPB6

RPA4

2U1RX input

to peripheral

RPn

Note: For input only, peripheral pin select functionality

does not have priority over TRISx settings.

Therefore, when configuring RPn pin for input,

the corresponding bit in the TRISx register must

also be configured for input (set to ‘1’).

11.3.5 OUTPUT MAPPING

In contrast to inputs, the outputs of the peripheral pin

select options are mapped on the basis of the pin. In

this case, a control register associated with a

particular pin dictates the peripheral output to be

mapped. The RPnR registers (Register 11-2) are

used to control output mapping. Like the [pin name]R

registers, each register contains sets of 4 bit fields.

The value of the bit field corresponds to one of the

peripherals, and that peripheral’s output is mapped

to the pin (see Tabl e 11-2 and Figure 11-3).

A null output is associated with the output register reset

value of ‘0’. This is done to ensure that remappable

outputs remain disconnected from all output pins by

default.

11.3.6 CONTROLLING CONFIGURATION

CHANGES

Because peripheral remapping can be changed during

run time, some restrictions on peripheral remapping

are needed to prevent accidental configuration

changes. PIC32 devices include two features to

prevent alterations to the peripheral map:

• Control register lock sequence

• Configuration bit select lock

11.3.6.1 Control Register Lock

Under normal operation, writes to the RPnR and [pin

name]R registers are not allowed. Attempted writes

appear to execute normally, but the contents of the

registers remain unchanged. To change these regis-

ters, they must be unlocked in hardware. The regis-

ter lock is controlled by the IOLOCK Configuration bit

(CFGCON<13>). Setting IOLOCK prevents writes to

the control registers; clearing IOLOCK allows writes.

To set or clear the IOLOCK bit, an unlock sequence

must be executed. Refer to Section 6. “Oscillator”

(DS60001112) in the “PIC32 Family Reference

Manual” for details.

11.3.6.2 Configuration Bit Select Lock

As an additional level of safety, the device can be

configured to prevent more than one write session to

the RPnR and [pin name]R registers. The IOL1WAY

Configuration bit (DEVCFG3<29>) blocks the IOLOCK

bit from being cleared after it has been set once. If

IOLOCK remains set, the register unlock procedure

does not execute, and the peripheral pin select control

registers cannot be written to. The only way to clear the

bit and re-enable peripheral remapping is to perform a

device Reset.

In the default (unprogrammed) state, IOL1WAY is set,

restricting users to one write session.

14.0 WATCHDOG TIMER (WDT)

The Watchdog Timer (WDT), when enabled, operates

from the internal Low-Power Oscillator (LPRC) clock

source and can be used to detect system software mal-

functions by resetting the device if the WDT is not

cleared periodically in software. Various WDT time-out

periods can be selected using the WDT postscaler. The

WDT can also be used to wake the device from Sleep

or Idle mode.

The following are some of the key features of the WDT

module:

• Configuration or software controlled

• User-configurable time-out period

• Can wake the device from Sleep or Idle

15.0 INPUT CAPTURE

The Input Capture module is useful in applications

requiring frequency (period) and pulse measurement.

The Input Capture module captures the 16-bit or 32-bit

value of the selected Time Base registers when an

event occurs at the ICx pin. The following events cause

capture events:

• Simple capture event modes:

- Capture timer value on every falling edge of

input at ICx pin

- Capture timer value on every rising edge of

input at ICx pin

- Capture timer value on every edge (rising

and falling)

- Capture timer value on every edge (rising

and falling), specified edge first.

• Prescaler capture event modes:

- Capture timer value on every 4th rising edge of

input at ICx pin

- Capture timer value on every 16th rising edge of

input at ICx pin

Each input capture channel can select between one of

two 16-bit timers (Timer2 or Timer3) for the time base,

or two 16-bit timers (Timer2 and Timer3) together to

form a 32-bit timer. The selected timer can use either

an internal or external clock.

The other operational features include:

• Device wake-up from capture pin during CPU

Sleep and Idle modes

• Interrupt on input capture event

• 4-word FIFO buffer for capture values

Interrupt optionally generated after 1, 2, 3, or 4

buffer locations are filled

• Input capture can also be used to provide

additional sources of external interrupts

16. 0 OU T P UT COMPAR E

The Output Compare module is used to generate a

single pulse or a train of pulses in response to selected

time base events. For all modes of operation, the

Output Compare module compares the values stored

in the OCxR and/or the OCxRS registers to the value in

the selected timer. When a match occurs, the Output

Compare module generates an event based on the

selected mode of operation.

The following are the key features of this module:

• Multiple Output Compare modules in a device

• Programmable interrupt generation on compare

event

• Single and Dual Compare modes

• Single and continuous output pulse generation

• Pulse-Width Modulation (PWM) mode

• Hardware-based PWM Fault detection and

automatic output disable

• Can operate from either of two available 16-bit

time bases or a single 32-bit time base

18.0 INTER-INTEGRATED CIRCUIT

The I

C module provides complete hardware support

for both Slave and Multi-Master modes of the I

C serial

communication standard. Figure 18-1 illustrates the

C module block diagram.

Each I

C module has a 2-pin interface: the SCLx pin is

clock and the SDAx pin is data.

Each I

C module offers the following key features:

•I

C interface supporting both master and slave

operation

•I

C Slave mode supports 7-bit and 10-bit addressing

•I

C Master mode supports 7-bit and 10-bit

addressing

•I

C port allows bidirectional transfers between

master and slaves

• Serial clock synchronization for the I

C port can

be used as a handshake mechanism to suspend

and resume serial transfer (SCLREL control)

•I

C supports multi-master operation; detects bus

collision and arbitrates accordingly

• Provides support for address bit masking

Note: This data sheet summarizes the features

of the PIC32MX1XX/2XX/5XX 64/100-pin

family of devices. It is not intended to be

a comprehensive reference source. To

19.0 UNIVERSAL ASYNCHRONOUS

RECEIVER TRANSMITTE R

(UART)

The UART module is one of the serial I/O modules

available in PIC32MX1XX/2XX/5XX 64/100-pin family

devices. The UART is a full-duplex, asynchronous

communication channel that communicates with

peripheral devices and personal computers through

protocols, such as RS-232, RS-485, LIN and IrDA

The module also supports the hardware flow control

option, with UxCTS and UxRTS pins, and also includes

an IrDA encoder and decoder.

The primary features of the UART module are:

• Full-duplex, 8-bit or 9-bit data transmission

• Even, odd or no parity options (for 8-bit data)

• One or two Stop bits

• Hardware auto-baud feature

• Hardware flow control option

• Fully integrated Baud Rate Generator (BRG) with

16-bit prescaler

• Baud rates ranging from 38 bps to 12.5 Mbps at

50 MHz

• 8-level deep First-In-First-Out (FIFO) transmit

data buffer

• 8-level deep FIFO receive data buffer

• Parity, framing and buffer overrun error detection

• Support for interrupt-only on address detect 

bit = 1)

• Separate transmit and receive interrupts

• Loopback mode for diagnostic support

• LIN Protocol support

• IrDA encoder and decoder with 16x baud clock

output for external IrDA encoder/decoder support

Figure 19-1 illustrates a simplified block diagram of the

UART.

20.0 PARALLEL MASTER PORT

(PMP)

The PMP is a parallel 8-bit or 16-bit input/output mod-

ule specifically designed to communicate with a wide

variety of parallel devices, such as communications

peripherals, LCDs, external memory devices and

microcontrollers. Because the interface to parallel

peripherals varies significantly, the PMP module is

highly configurable.

The following are the key features of the PMP module:

• 8-bit,16-bit interface

• Up to 16 programmable address lines

• Up to two Chip Select lines

• Programmable strobe options:

- Individual read and write strobes, or

- Read/write strobe with enable strobe

- Selectable polarity

• Address auto-increment/auto-decrement

• Programmable address/data multiplexing

• Programmable polarity on control signals

• Parallel Slave Port support:

- Legacy addressable

- Address support

• Read and Write 4-byte deep auto-incrementing buffer

• Programmable Wait states

• Operate during CPU Sleep and Idle modes

• Fast bit manipulation using CLR, SET and INV

registers

• Freeze option for in-circuit debugging

This register is used for Read operations in the Enhanced Parallel Slave mode and Write operations for Dual

Buffer Master mode.

In Dual Buffer Master mode, the DUALBUF bit (PMPCON<17>) = 1, a write to the MSB triggers the trans-

action on the PMP port. When MODE16 = 1, MSB = DATAOUT<15:8>. When MODE16 = 0,

MSB = DATAOUT<7:0>.

Note: In Master mode, a read will return the last value written to the register. In Slave mode, a read will return

indeterminate results.

This register is used for both Parallel Master Port mode and Enhanced Parallel Slave mode.

In Parallel Master mode, a write to the MSB triggers the write transaction on the PMP port. Similarly, a read

to the MSB triggers the read transaction on the PMP port.

When MODE16 = 1, MSB = DATAIN<15:8>. When MODE16 = 0, MSB = DATAIN<7:0>.

Note: This register is not used in Dual Buffer Master mode (i.e., DUALBUF bit (PMPCON<17>) = 1).

• 24-hour format (military time)

• Visibility of one-half second period

• Provides calendar: Weekday, date, month and

year

• Alarm intervals are configurable for half of a

second, one second, 10 seconds, one minute, 10

minutes, one hour, one day, one week, one month

and one year

• Alarm repeat with decrementing counter

• Alarm with indefinite repeat: Chime

• Year range: 2000 to 2099

• Leap year correction

• BCD format for smaller firmware overhead

• Optimized for long-term battery operation

• Fractional second synchronization

• User calibration of the clock crystal frequency with

auto-adjust

• Calibration range: 0.66 seconds error per month

bit 14 CHIME: Chime Enable bit

(2)

1 = Chime is enabled – ARPT<7:0> is allowed to rollover from 0x00 to 0xFF

0 = Chime is disabled – ARPT<7:0> stops once it reaches 0x00

bit 13 PIV: Alarm Pulse Initial Value bit

(2)

When ALRMEN = 0, PIV is writable and determines the initial value of the Alarm Pulse.

When ALRMEN = 1, PIV is read-only and returns the state of the Alarm Pulse.

bit 12 ALRMSYNC: Alarm Sync bit

(3)

1 = ARPT<7:0> and ALRMEN may change as a result of a half second rollover during a read. 

The ARPT must be read repeatedly until the same value is read twice. This must be done since multiple

bits may be changing, which are then synchronized to the PB clock domain

0 = ARPT<7:0> and ALRMEN can be read without concerns of rollover because the prescaler is > 32 RTC

clocks away from a half-second rollover

000 = Clearing SAMP bit ends sampling and starts conversion

Note 1: When using 1:1 PBCLK divisor, the user software should not read/write the peripheral’s SFRs in the

SYSCLK cycle immediately following the instruction that clears the module’s ON bit.

2: If ASAM = 0, software can write a ‘1’ to start sampling. This bit is automatically set by hardware if

ASAM = 1. If SSRC = 0, software can write a ‘0’ to end sampling and start conversion. If SSRC



0, this

bit is automatically cleared by hardware to end sampling and start conversion.

3: This bit is automatically set by hardware when analog-to-digital conversion is complete. Software can

write a ‘0’ to clear this bit (a write of ‘1’ is not allowed). Clearing this bit does not affect any operation

already in progress. This bit is automatically cleared by hardware at the start of a new conversion.

bit 31-0 C1FIFOBA<31:0>: CAN FIFO Base Address bits

These bits define the base address of all message buffers. Individual message buffers are located based

on the size of the previous message buffers. This address is a physical address. Bits <1:0> are read-only

and read as ‘0’, forcing the messages to be 32-bit word-aligned in device RAM.

Note 1: This bit is unimplemented and will always read ‘0’, which forces word-alignment of messages.

Note: This register can only be modified when the CAN module is in Configuration mode (OPMOD<2:0>

(C1CON<23:21>) = 100).

25.0 COMPARATO R VOLTAGE

REFERENCE (CV

REF

)

The CV

REF

module is a 16-tap, resistor ladder network

that provides a selectable reference voltage. Although

its primary purpose is to provide a reference for the

analog comparators, it also may be used independently

of them.

A block diagram of the module is illustrated in

Figure 25-1. The resistor ladder is segmented to

provide two ranges of voltage reference values and has

a power-down function to conserve power when the

reference is not being used. The module’s supply refer-

ence can be provided from either device V

or an

external voltage reference. The CV

REF

output is avail-

able for the comparators and typically available for pin

output.

The CV

REF

module has the following features:

• High and low range selection

• Sixteen output levels available for each range

• Internally connected to comparators to conserve

device pins

• Output can be connected to a pin

26.0 CHARGE TIME

MEASUREMENT UNIT (CTMU)

The Charge Time Measurement Unit (CTMU) is a

flexible analog module that has a configurable current

source with a digital configuration circuit built around it.

The CTMU can be used for differential time

measurement between pulse sources and can be used

for generating an asynchronous pulse. By working with

other on-chip analog modules, the CTMU can be used

for high resolution time measurement, measure

capacitance, measure relative changes in capacitance

or generate output pulses with a specific time delay.

The CTMU is ideal for interfacing with capacitive-based

sensors.

The CTMU module includes the following key features:

• Up to 13 channels available for capacitive or time

measurement input

• On-chip precision current source

• 16-edge input trigger sources

• Selection of edge or level-sensitive inputs

• Polarity control for each edge source

• Control of edge sequence

• Control of response to edges

• High precision time measurement

• Time delay of external or internal signal asynchro-

nous to system clock

• Integrated temperature sensing diode

• Control of current source during auto-sampling

• Four current source ranges

• Time measurement resolution of one nanosecond

A block diagram of the CTMU is shown in Figure 26-1.

27.0 POWER-SAVING FEATURES

This section describes power-saving features for the

PIC32MX1XX/2XX/5XX 64/100-pin family of devices.

These PIC32 devices offer a total of nine methods

and modes, organized into two categories, that allow

the user to balance power consumption with device

performance. In all of the methods and modes

described in this section, power-saving is controlled by

software.

27.1 Power Saving with CPU Running

When the CPU is running, power consumption can be

controlled by reducing the CPU clock frequency,

lowering the PBCLK and by individually disabling

modules. These methods are grouped into the

following categories:

• FRC Run mode: the CPU is clocked from the FRC

clock source with or without postscalers.

• LPRC Run mode: the CPU is clocked from the

LPRC clock source.

•S

OSC

Run mode: the CPU is clocked from the

OSC

clock source.

In addition, the Peripheral Bus Scaling mode is available

where peripherals are clocked at the programmable

fraction of the CPU clock (SYSCLK).

27.2 CPU Halted Methods

The device supports two power-saving modes, Sleep

and Idle, both of which Halt the clock to the CPU. These

modes operate with all clock sources, as listed below:

•P

OSC

Idle mode: the system clock is derived from

the P

OSC

. The system clock source continues to

operate. Peripherals continue to operate, but can

optionally be individually disabled.

• FRC Idle mode: the system clock is derived from

the FRC with or without postscalers. Peripherals

continue to operate, but can optionally be

individually disabled.

•S

OSC

Idle mode: the system clock is derived from

the S

OSC

. Peripherals continue to operate, but

can optionally be individually disabled.

• LPRC Idle mode: the system clock is derived from

the LPRC. Peripherals continue to operate, but

can optionally be individually disabled. This is the

lowest power mode for the device with a clock

running.

• Sleep mode: the CPU, the system clock source

and any peripherals that operate from the system

clock source are Halted. Some peripherals can

operate in Sleep using specific clock sources.

This is the lowest power mode for the device.

27.3 Power-Saving Operation

Peripherals and the CPU can be Halted or disabled to

further reduce power consumption.

27.3.1 SLEEP MODE

Sleep mode has the lowest power consumption of the

device power-saving operating modes. The CPU and

most peripherals are Halted. Select peripherals can

continue to operate in Sleep mode and can be used to

wake the device from Sleep. See the individual

peripheral module sections for descriptions of

behavior in Sleep.

Sleep mode includes the following characteristics:

• The CPU is Halted.

• The system clock source is typically shutdown.

See Section 27.3.3 “Peripheral Bus Scaling

Method” for specific information.

• There can be a wake-up delay based on the

oscillator selection.

• The Fail-Safe Clock Monitor (FSCM) does not

operate during Sleep mode.

• The BOR circuit remains operative during Sleep

mode.

• The WDT, if enabled, is not automatically cleared

prior to entering Sleep mode.

• Some peripherals can continue to operate at

limited functionality in Sleep mode. These periph-

erals include I/O pins that detect a change in the

input signal, WDT, ADC, UART and peripherals

that use an external clock input or the internal

LPRC oscillator (e.g., RTCC, Timer1 and Input

Capture).

• I/O pins continue to sink or source current in the

same manner as they do when the device is not in

Sleep.

• The USB module can override the disabling of the

Posc or FRC. Refer to the USB section for

specific details.

• Modules can be individually disabled by software

prior to entering Sleep in order to further reduce

consumption.

Note: This data sheet summarizes the features

of the PIC32MX1XX/2XX/5XX 64/100-pin

family of devices. It is not intended to be

a comprehensive reference source. To

complement the information in this data

sheet, refer to Section 10. “Power-

Saving Features” (DS60001130) in the

“PIC32 Family Reference Manual”, which

is available from the Microchip web site

(www.microchip.com/PIC32).

DS60001290E-page 286  2014-2017 Microchip Technology Inc.

The processor will exit, or ‘wake-up’, from Sleep on one

of the following events:

• On any interrupt from an enabled source that is

operating in Sleep. The interrupt priority must be

greater than the current CPU priority.

• On any form of device Reset

• On a WDT time-out

If the interrupt priority is lower than or equal to the

current priority, the CPU will remain Halted, but the

PBCLK will start running and the device will enter into

Idle mode.

27.3.2 IDLE MODE

In Idle mode, the CPU is Halted but the System Clock

(SYSCLK) source is still enabled. This allows peripher-

als to continue operation when the CPU is Halted.

Peripherals can be individually configured to Halt when

entering Idle by setting their respective SIDL bit.

Latency, when exiting Idle mode, is very low due to the

CPU oscillator source remaining active.

The device enters Idle mode when the SLPEN bit

(OSCCON<4>) is clear and a WAIT instruction is

executed.

The processor will wake or exit from Idle mode on the

following events:

• On any interrupt event for which the interrupt

source is enabled. The priority of the interrupt

event must be greater than the current priority of

the CPU. If the priority of the interrupt event is

lower than or equal to current priority of the CPU,

the CPU will remain Halted and the device will

remain in Idle mode.

• On any form of device Reset

• On a WDT time-out interrupt

27.3.3 PERIPHERAL BUS SCALING

METHOD

Most of the peripherals on the device are clocked using

the PBCLK. The peripheral bus can be scaled relative to

the SYSCLK to minimize the dynamic power consumed

by the peripherals. The PBCLK divisor is controlled by

PBDIV<1:0> (OSCCON<20:19>), allowing SYSCLK to

PBCLK ratios of 1:1, 1:2, 1:4 and 1:8. All peripherals

using PBCLK are affected when the divisor is changed.

Peripherals such as the USB, Interrupt Controller, DMA,

and the bus matrix are clocked directly from SYSCLK.

As a result, they are not affected by PBCLK divisor

changes.

Changing the PBCLK divisor affects:

• The CPU to peripheral access latency. The CPU

has to wait for next PBCLK edge for a read to

complete. In 1:8 mode, this results in a latency of

one to seven SYSCLKs.

• The power consumption of the peripherals. Power

consumption is directly proportional to the

frequency at which the peripherals are clocked.

The greater the divisor, the lower the power

consumed by the peripherals.

To minimize dynamic power, the PB divisor should be

chosen to run the peripherals at the lowest frequency

that provides acceptable system performance. When

selecting a PBCLK divider, peripheral clock require-

ments, such as baud rate accuracy, should be taken

into account. For example, the UART peripheral may

not be able to achieve all baud rate values at some

PBCLK divider depending on the SYSCLK value.

Note 1: Changing the PBCLK divider ratio

requires recalculation of peripheral tim-

ing. For example, assume the UART is

configured for 9600 baud with a PB clock

ratio of 1:1 and a P

OSC

of 8 MHz. When

the PB clock divisor of 1:2 is used, the

input frequency to the baud clock is cut in

half; therefore, the baud rate is reduced

to 1/2 its former value. Due to numeric

truncation in calculations (such as the

baud rate divisor), the actual baud rate

may be a tiny percentage different than

expected. For this reason, any timing cal-

culation required for a peripheral should

be performed with the new PB clock fre-

quency instead of scaling the previous

value based on a change in the PB divisor

ratio.

2: Oscillator start-up and PLL lock delays

are applied when switching to a clock

source that was disabled and that uses a

crystal and/or the PLL. For example,

assume the clock source is switched from

OSC

to LPRC just prior to entering Sleep

in order to save power. No oscillator start-

up delay would be applied when exiting

Idle. However, when switching back to

OSC

, the appropriate PLL and/or

oscillator start-up/lock delays would be

applied.

27.4 Peripher a l Module Disable

The Peripheral Module Disable (PMD) registers

provide a method to disable a peripheral module by

stopping all clock sources supplied to that module.

When a peripheral is disabled using the appropriate

PMD control bit, the peripheral is in a minimum power

consumption state. The control and status registers

associated with the peripheral are also disabled, so

writes to those registers do not have effect and read

values are invalid.

To disable a peripheral, the associated PMDx bit must

be set to ‘1’. To enable a peripheral, the associated

PMDx bit must be cleared (default). See Table 27-1 for

more information.

TABLE 27-1: PERIPHERAL MODULE DISABLE BITS AND LOCATIONS

Note: Disabling a peripheral module while it’s

ON bit is set, may result in undefined

behavior. The ON bit for the associated

peripheral module must be cleared prior to

disable a module via the PMDx bits.

27.4.1 CONTROLLING CONFIGURATION

CHANGES

Because peripherals can be disabled during run time,

some restrictions on disabling peripherals are needed

to prevent accidental configuration changes. PIC32

devices include two features to prevent alterations to

enabled or disabled peripherals:

• Control register lock sequence

• Configuration bit select lock

27.4.1.1 Control Register Lock

Under normal operation, writes to the PMDx registers

are not allowed. Attempted writes appear to execute

normally, but the contents of the registers remain

unchanged. To change these registers, they must be

unlocked in hardware. The register lock is controlled by

the PMDLOCK Configuration bit (CFGCON<12>). Set-

ting PMDLOCK prevents writes to the control registers; 

clearing PMDLOCK allows writes.

To set or clear PMDLOCK, an unlock sequence must

be executed. Refer to Section 6. “Oscillator”

(DS60001112) in the “PIC32 Family Reference

Manual” for details.

27.4.1.2 Configuration Bit Select Lock

As an additional level of safety, the device can be

configured to prevent more than one write session to

the PMDx registers. The PMDL1WAY Configuration bit

(DEVCFG3<28>) blocks the PMDLOCK bit from being

cleared after it has been set once. If PMDLOCK

remains set, the register unlock procedure does not

execute, and the peripheral pin select control registers

cannot be written to. The only way to clear the bit and

re-enable PMD functionality is to perform a device

Reset.

28.3 On-Chip Voltage Regulat or

All PIC32MX1XX/2XX/5XX 64/100-pin devices’ core

and digital logic are designed to operate at a nominal

1.8V. To simplify system designs, most devices in the

PIC32MX1XX/2XX/5XX 64/100-pin family incorporate

an on-chip regulator providing the required core logic

voltage from V

A low-ESR capacitor (such as tantalum) must be

connected to the V

CAP

pin (see Figure 28-1). This

helps to maintain the stability of the regulator. The

recommended value for the filter capacitor is provided

in Section 31.1 “DC Ch arac te r is tics” .

28.3.1 HIGH VOLTAGE DETECT (HVD)

The HVD module monitors the core voltage at the V

CAP

pin. If a voltage above the required level is detected on

CAP

, the I/O pins are disabled and the device is held

in Reset as long as the HVD condition persists. See

parameter HV10 (V

HVD

) in Tabl e 31-11 in Section 31.1

“DC Characteristics” for more information.

28.3.2 ON-CHIP REGULATOR AND POR

It takes a fixed delay for the on-chip regulator to generate

an output. During this time, designated as T

, code

execution is disabled. T

is applied every time the

device resumes operation after any power-down,

including Sleep mode.

28.3.3 ON-CHIP REGULATOR AND BOR

PIC32MX1XX/2XX/5XX 64/100-pin devices also have

a simple brown-out capability. If the voltage supplied to

the regulator is inadequate to maintain a regulated

level, the regulator Reset circuitry will generate a

Brown-out Reset. This event is captured by the BOR

flag bit (RCON<1>). The brown-out voltage levels are

specific in Section 31.1 “DC Characteristics”.

FIGURE 28-1: CONNE CTIONS FOR THE

ON-CHIP REGULATOR

28.4 Programming and Diagnostics

PIC32MX1XX/2XX/5XX 64/100-pin devices provide a

complete range of programming and diagnostic fea-

tures that can increase the flexibility of any application

using them. These features allow system designers to

include:

• Simplified field programmability using two-wire 

In-Circuit Serial Programming™ (ICSP™)

interfaces

• Debugging using ICSP

• Programming and debugging capabilities using

the EJTAG extension of JTAG

• JTAG boundary scan testing for device and board

diagnostics

PIC32 devices incorporate two programming and diag-

nostic modules that provide a range of functions to the

application developer.

30.2 MPLAB XC Compilers

The MPLAB XC Compilers are complete ANSI C

compilers for all of Microchip’s 8, 16, and 32-bit MCU

and DSC devices. These compilers provide powerful

integration capabilities, superior code optimization and

ease of use. MPLAB XC Compilers run on Windows,

Linux or MAC OS X.

For easy source level debugging, the compilers provide

debug information that is optimized to the MPLAB X

IDE.

The free MPLAB XC Compiler editions support all

devices and commands, with no time or memory

restrictions, and offer sufficient code optimization for

most applications.

MPLAB XC Compilers include an assembler, linker and

utilities. The assembler generates relocatable object

files that can then be archived or linked with other relo-

catable object files and archives to create an execut-

able file. MPLAB XC Compiler uses the assembler to

produce its object file. Notable features of the assem-

bler include:

• Support for the entire device instruction set

• Support for fixed-point and floating-point data

• Command-line interface

• Rich directive set

• Flexible macro language

• MPLAB X IDE compatibility

30.3 MPASM Assembler

The MPASM Assembler is a full-featured, universal

macro assembler for PIC10/12/16/18 MCUs.

The MPASM Assembler generates relocatable object

files for the MPLINK Object Linker, Intel

standard HEX

files, MAP files to detail memory usage and symbol

reference, absolute LST files that contain source lines

and generated machine code, and COFF files for

debugging.

The MPASM Assembler features include:

• Integration into MPLAB X IDE projects

• User-defined macros to streamline 

assembly code

• Conditional assembly for multipurpose 

source files

• Directives that allow complete control over the

assembly process

30.4 MPLINK Object Linker/

MPLIB Object Librarian

The MPLINK Object Linker combines relocatable

objects created by the MPASM Assembler. It can link

relocatable objects from precompiled libraries, using

directives from a linker script.

The MPLIB Object Librarian manages the creation and

modification of library files of precompiled code. When

a routine from a library is called from a source file, only

the modules that contain that routine will be linked in

with the application. This allows large libraries to be

used efficiently in many different applications.

The object linker/library features include:

• Efficient linking of single libraries instead of many

smaller files

• Enhanced code maintainability by grouping

related modules together

• Flexible creation of libraries with easy module

listing, replacement, deletion and extraction

30.5 MPLAB Assembler, Linker and

Librarian for Various Device

Families

MPLAB Assembler produces relocatable machine

code from symbolic assembly language for PIC24,

PIC32 and dsPIC DSC devices. MPLAB XC Compiler

uses the assembler to produce its object file. The

assembler generates relocatable object files that can

then be archived or linked with other relocatable object

files and archives to create an executable file. Notable

features of the assembler include:

• Support for the entire device instruction set

• Support for fixed-point and floating-point data

• Command-line interface

• Rich directive set

• Flexible macro language

• MPLAB X IDE compatibility

30.6 MPLAB X SIM Software Simulator

The MPLAB X SIM Software Simulator allows code

development in a PC-hosted environment by simulat-

ing the PIC MCUs and dsPIC DSCs on an instruction

level. On any given instruction, the data areas can be

examined or modified and stimuli can be applied from

a comprehensive stimulus controller. Registers can be

logged to files for further run-time analysis. The trace

buffer and logic analyzer display extend the power of

the simulator to record and track program execution,

actions on I/O, most peripherals and internal registers.

The MPLAB X SIM Software Simulator fully supports

symbolic debugging using the MPLAB XC Compilers,

and the MPASM and MPLAB Assemblers. The soft-

ware simulator offers the flexibility to develop and

debug code outside of the hardware laboratory envi-

ronment, making it an excellent, economical software

development tool.

30.7 MPLAB R E AL ICE In -Circ u it

Note 1: Data in “Typical” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only

and are not tested.

2: The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified

levels represent normal operating conditions. Higher leakage current may be measured at different input

voltages.

3: Negative current is defined as current sourced by the pin.

4: This parameter is characterized, but not tested in manufacturing.

5: See the “Device Pin Tables” section for the 5V-tolerant pins.

6: The V

specifications are only in relation to externally applied inputs, and not with respect to the user-

selectable internal pull-ups. External open drain input signals utilizing the internal pull-ups of the PIC32

device are guaranteed to be recognized only as a logic “high” internally to the PIC32 device, provided that

the external load does not exceed the minimum value of I

CNPU

. For External “input” logic inputs that require

a pull-up source, to guarantee the minimum V

of those components, it is recommended to use an

external pull-up resistor rather than the internal pull-ups of the PIC32 device.

The minimum SYSCLK for row programming is 4 MHz. Care should be taken to minimize bus activities

during row programming, such as suspending any memory-to-memory DMA operations. If heavy bus

loads are expected, selecting Bus Matrix Arbitration mode 2 (rotating priority) may be necessary. The

default Arbitration mode is mode 1 (CPU has lowest priority).

Refer to the “PIC32 Flash Programming Specification” (DS60001145) for operating conditions during

programming and erase cycles.

32.0 50 MHz ELECTRICAL CHARACTERISTICS

This section provides an overview of the PIC32MX1XX/2XX/5XX 64/100-pin Family electrical characteristics for devices

operating at 50 MHz.

The specifications for 50 MHz are identical to those shown in

Section 31.0 “ 40 M Hz Ele ctric al C h arac ter isti cs”

, with

the exception of the parameters listed in this chapter.

Parameters in this chapter begin with the letter “M”, which denotes 50 MHz operation. For example, parameter DC29a

Section 31.0 “40 MHz Electrical Characteristics”

, is the up to 40 MHz operation equivalent for MDC29a.

Absolute maximum ratings for the PIC32MX1XX/2XX/5XX 64/100-pin Family 50 MHz devices are listed below.

Exposure to these maximum rating conditions for extended periods may affect device reliability. Functional operation of

the device at these or any other conditions, above the parameters indicated in the operation listings of this specification,

is not implied.

Note 1:

Stresses above those listed under

“Abso lute Maxim um Ratings”

may cause permanent damage to the

device. This is a stress rating only and functional operation of the device at those or any other conditions,

above those indicated in the operation listings of this specification, is not implied. Exposure to maximum

rating conditions for extended periods may affect device reliability.

Maximum allowable current is a function of device maximum power dissipation (see Tab l e 32-2).

Note 1:

A device’s I

supply current is mainly a function of the operating voltage and frequency. Other factors,

such as PBCLK (Peripheral Bus Clock) frequency, number of peripheral modules enabled, internal code

execution pattern, execution from Program Flash memory vs. SRAM, I/O pin loading and switching rate,

oscillator type, as well as temperature, can have an impact on the current consumption.

The test conditions for I

measurements are as follows:

• Oscillator mode is EC (for 8 MHz and below) and EC+PLL (for above 8 MHz) with OSC1 driven by

external square wave from rail-to-rail, (OSC1 input clock input over/undershoot < 100 mV required)

• OSC2/CLKO is configured as an I/O input pin

• USB PLL oscillator is disabled if the USB module is implemented, PBCLK divisor = 1:8

• CPU, Program Flash, and SRAM data memory are operational, SRAM data memory Wait states = 1

• No peripheral modules are operating, (ON bit = 0), but the associated PMD bit is cleared

• WDT, Clock Switching, Fail-Safe Clock Monitor, and Secondary Oscillator are disabled

• All I/O pins are configured as inputs and pulled to V

•MCLR

= V

• CPU executing while(1) statement from Flash

RTCC and JTAG are disabled

Data in “Typical” column is at 3.3V, 25°C at specified operating frequency unless otherwise stated.

Parameters are for design guidance only and are not tested.

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
