2.0 GUIDELINES FOR GETTING

STARTED WITH 16-BIT

DIGITAL SIGNAL

CONTROLLERS AND

MICROCONTROLLERS

2.1 Basic Connection Requirements

Getting started with the dsPIC33EPXXXGP50X,

dsPIC33EPXXXMC20X/50X, and

PIC24EPXXXGP/MC20X families 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 VDD and VSS pins

(see Section 2.2 “Decoupling Capacitors”)

• All AVDD and AVSS pins (regardless if ADC module

is not used)

(see Section 2.2 “Decoupling Capacitors”)

•V

CAP

(see Section 2.3 “CPU Logic Filter Capacitor

Connection (VCAP)”)

•MCLR

(see Section 2.4 “Master Clear (MCLR) Pin”)

• PGECx/PGEDx pins used for In-Circuit Serial

Programming™ (ICSP™) and debugging purposes

(see Section 2.5 “ICSP Pins”)

• OSC1 and OSC2 pins when external oscillator

source is used

(see Section 2.6 “External Oscillator Pins”)

Additionally, the following pins may be required:

•V

REF+/VREF- pins are used when external voltage

reference for ADC module is implemented

2.2 Decoupling Capacitors

The use of decoupling capacitors on every pair of

power supply pins, such as VDD, VSS, AVDD and

AVSS is required.

Consider the following criteria when using decoupling

capacitors:

•Value and type of capacitor: Recommendation

of 0.1 µF (100 nF), 10-20V. This capacitor should

be a low-ESR and have resonance frequency in

the range of 20 MHz and higher. It is

recommended to use ceramic capacitors.

•Placement on the printed circuit board: The

decoupling capacitors should be placed as close

to the pins as possible. It is recommended to

place the capacitors 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 high frequency noise: If the board is

experiencing high frequency noise, above 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.

•Maximizing performance: 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 1: This data sheet summarizes the features

of the dsPIC33EPXXXGP50X,

dsPIC33EPXXXMC20X/50X, and

PIC24EPXXXGP/MC20X families of

devices. It is not intended to be a compre-

hensive reference source. To comple-

ment the information in this data sheet,

refer to the related section of the

“dsPIC33E/PIC24E Family Reference

Manual”, which is available from the

Microchip web site (www.microchip.com)

2: Some registers and associated bits

described in this section may not be

available on all devices. Refer to

Section 4.0 “Memory Organization” in

this data sheet for device-specific register

and bit information.

Note: The AVDD and AVSS pins must be

connected independent of the ADC

voltage reference source.

FIGURE 2-1: RECOMMENDED

MINIMUM CONNECTION

2.2.1 TANK CAPACITORS

On boards with power traces running longer than six

inches in length, it is suggested to use a tank capacitor

for integrated circuits including DSCs to supply a local

power source. The value of the tank capacitor should

be determined based on the trace resistance that con-

nects the power supply source to the device, and the

maximum current drawn by the device in the applica-

tion. In other words, select the tank capacitor so that it

meets the acceptable voltage sag at the device. Typical

values range from 4.7 µF to 47 µF.

2.3 CPU Logic Filter Capacitor

Connection (VCAP)

A low-ESR (< 1 Ohms) capacitor is required on the

VCAP pin, which is used to stabilize the voltage

regulator output voltage. The VCAP pin must not be

connected to VDD, and must have a capacitor greater

than 4.7 µF (10 µF is recommended), 16V connected

to ground. The type can be ceramic or tantalum. See

Section 30.0 “Electrical Characteristics” for

additional information.

The placement of this capacitor should be close to the

VCAP pin. It is recommended that the trace length not

exceeds one-quarter inch (6 mm). See Section 27.3

“On-Chip Voltage Regulator” for details.

2.4 Master Clear (MCLR) Pin

The MCLR pin provides two specific device

functions:

• Device Reset

• Device Programming and Debugging.

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 (VIH and VIL) 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 shown 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 as shown in Figure 2-2 within

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

Note 1: As an option, instead of a hard-wired connection, an

impedance should be less than 1Ω and the inductor

capacity greater than 10 mA.

2.5 ICSP Pins

The PGECx and PGEDx pins are used for ICSP and

debugging purposes. 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 con-

nector 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

(VIH) and input low (VIL) 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® PICkit™ 3, MPLAB ICD 3, or MPLAB REAL

ICE™.

For more information on ICD 2, ICD 3 and REAL ICE

connection requirements, refer to the following

documents that are available on the Microchip web

site.

Guide” DS51616

•“Using MPLAB® REAL ICE™ In-Circuit Emulator”

(poster) DS51749

2.6 External Oscillator Pins

Many DSCs have options for at least two oscillators: a

high-frequency primary oscillator and a low-frequency

secondary oscillator. For details, see Section 9.0

“Oscillator Configuration” for details.

The oscillator circuit should be placed on the same

side of the board as the device. Also, place the

oscillator circuit close to the respective oscillator pins,

not exceeding one-half inch (12 mm) distance

between them. The load capacitors should be placed

next to the oscillator itself, 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 shown in Figure 2-3.

CIRCUIT

Oscillator Pins

dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/50X, AND PIC24EPXXXGP/MC20X

2.7 Oscillator Value Conditions on

Device Start-up

If the PLL of the target device is enabled and

configured for the device start-up oscillator, the

maximum oscillator source frequency must be limited

to 3 MHz < FIN < 5.5 MHz to comply with device PLL

start-up conditions. This means that if the external

oscillator frequency is outside this range, the

application must start-up in the FRC mode first. The

default PLL settings after a POR with an oscillator

frequency outside this range will violate the device

operating speed.

Once the device powers up, the application firmware

can initialize the PLL SFRs, CLKDIV and PLLDBF to a

suitable value, and then perform a clock switch to the

Oscillator + PLL clock source. Note that clock switching

must be enabled in the device Configuration Word.

2.8 Unused I/Os

Unused I/O pins should be configured as outputs and

driven to a logic-low state.

Alternatively, connect a 1k to 10k resistor between VSS

and unused pins and drive the output to logic low.

2.9 Application Examples

• Induction heating

• Uninterruptable Power Supplies (UPS)

• DC/AC inverters

• Compressor motor control

3.0 CPU

The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/

50X, and PIC24EPXXXGP/MC20X CPU have a 16-bit

(data) modified Harvard architecture with an enhanced

instruction set, including significant support for digital

signal processing. The CPU has a 24-bit instruction

word, with a variable length opcode field. The Program

Counter (PC) is 23 bits wide and addresses up to

4M x 24 bits of user program memory space.

An instruction prefetch mechanism helps maintain

throughput and provides predictable execution. Most

instructions execute in a single-cycle effective execu-

tion rate, with the exception of instructions that change

the program flow, the double-word move (MOV.D)

instruction, PSV accesses, and the table instructions.

Overhead free program loop constructs are supported

using the DO and REPEAT instructions, both of which

are interruptible at any point.

3.1 Registers

The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/

50X, and PIC24EPXXXGP/MC20X devices have six-

teen 16-bit Working registers in the programmer’s

model. Each of the Working registers can act as a data,

address or address offset register. The 16th Working

interrupts and calls.

3.2 Instruction Set

The instruction set for dsPIC33EPXXXGP50X and

dsPIC33EPXXXMC20X/50X devices has two classes of

instructions: the MCU class of instructions and the DSP

class of instructions. The instruction set for

PIC24EPXXXGP/MC20X devices has the MCU class of

instructions only and does not support DSP instructions.

These two instruction classes are seamlessly integrated

into the architecture and execute from a single execution

unit. The instruction set includes many addressing modes

and was designed for optimum C compiler efficiency.

3.3 Data Space Addressing

The base data space can be addressed as 4K words or

8 Kbytes and is split into two blocks, referred to as X

and Y data memory. Each memory block has its own

independent Address Generation Unit (AGU). The

MCU class of instructions operate solely through the X

memory AGU, which accesses the entire memory map

as one linear data space. On dsPIC33EPXXXMC20X/

50X and dsPIC33EPXXXGP50X devices, certain DSP

instructions operate through the X and Y AGUs to sup-

port dual operand reads, which splits the data address

space into two parts. The X and Y data space boundary

is device specific.

The upper 4 Kbytes of the data space memory map can

optionally be mapped into program space at any 16K

program word boundary. The program-to-data-space

mapping feature, known as Program Space Visibility

(PSV), lets any instruction access program space as if

it were data space. Moreover, the Base Data Space

address is used in conjunction with a read or write page

Data Space (EDS) address. The EDS can be

addressed as 8 Mwords or 16 Mbytes. Refer to

Section 3. “Data Memory” (DS70595) and Section 4.

“Program Memory” (DS70613) in the “dsPIC33E/

PIC24E Family Reference Manual” for more details on

EDS, PSV and table accesses.

On dsPIC33EPXXXMC20X/50X and

dsPIC33EPXXXGP50X devices, overhead-free

circular buffers (Modulo Addressing) are supported in

both X and Y address spaces. The Modulo Addressing

removes the software boundary-checking overhead for

DSP algorithms. The X AGU circular addressing can be

used with any of the MCU class of instructions. The X

AGU also supports Bit-Reverse Addressing to greatly

simplify input or output data reordering for radix-2 FFT

algorithms. PIC24EPXXXGP/MC20X devices do not

support Modulo and Bit-Reverse Addressing.

3.4 Addressing Modes

The CPU supports these addressing modes:

• Inherent (no operand)

• Relative

•Literal

• Memory Direct

• Register Direct

• Register Indirect

Each instruction is associated with a predefined

Addressing mode group, depending upon its functional

requirements. As many as six Addressing modes are

supported for each instruction.

dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/50X,

and PIC24EPXXXGP/MC20X is shown in Figure 3-2.

All registers in the programmer’s model are memory

mapped and can be manipulated directly by

instructions. Table 3-1 lists a description of each

In addition to the registers contained in the

3.8 Arithmetic Logic Unit (ALU)

The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/

50X, and PIC24EPXXXGP/MC20X ALU is 16 bits wide

and is capable of addition, subtraction, bit shifts and

logic operations. Unless otherwise mentioned,

arithmetic operations are two’s complement in nature.

Depending on the operation, the ALU can affect the

values of the Carry (C), Zero (Z), Negative (N),

Overflow (OV) and Digit Carry (DC) Status bits in the

SR register. The C and DC Status bits operate as

Borrow and Digit Borrow bits, respectively, for

subtraction operations.

The ALU can perform 8-bit or 16-bit operations,

depending on the mode of the instruction that is used.

Data for the ALU operation can come from the W

addressing mode of the instruction. Likewise, output

data from the ALU can be written to the W register array

or a data memory location.

Refer to the “16-bit MCU and DSC Programmer’s

Reference Manual” (DS70157) for information on the

SR bits affected by each instruction.

The core CPU incorporates hardware support for both

multiplication and division. This includes a dedicated

hardware multiplier and support hardware for 16-bit

divisor division.

3.8.1 MULTIPLIER

Using the high-speed 17-bit x 17-bit multiplier, the ALU

supports unsigned, signed, or mixed-sign operation in

several MCU multiplication modes:

• 16-bit x 16-bit signed

• 16-bit x 16-bit unsigned

• 16-bit signed x 5-bit (literal) unsigned

• 16-bit signed x 16-bit unsigned

• 16-bit unsigned x 5-bit (literal) unsigned

• 16-bit unsigned x 16-bit signed

• 8-bit unsigned x 8-bit unsigned

3.8.2 DIVIDER

The divide block supports 32-bit/16-bit and 16-bit/16-bit

signed and unsigned integer divide operations with the

following data sizes:

• 32-bit signed/16-bit signed divide

• 32-bit unsigned/16-bit unsigned divide

• 16-bit signed/16-bit signed divide

• 16-bit unsigned/16-bit unsigned divide

The quotient for all divide instructions ends up in W0

and the remainder in W1. 16-bit signed and unsigned

DIV instructions can specify any W register for both

the 16-bit divisor (Wn) and any W register (aligned)

pair (W(m + 1):Wm) for the 32-bit dividend. The divide

algorithm takes one cycle per bit of divisor, so both

32-bit/16-bit and 16-bit/16-bit instructions take the

same number of cycles to execute.

3.9 DSP Engine

(dsPIC33EPXXXMC20X/50X and

dsPIC33EPXXXGP50X Devices

Only)

The DSP engine consists of a high-speed 17-bit x

17-bit multiplier, a 40-bit barrel shifter and a 40-bit

adder/subtracter (with two target accumulators, round

and saturation logic).

The DSP engine can also perform inherent accumula-

tor-to-accumulator operations that require no additional

data. These instructions are ADD, SUB and NEG.

The DSP engine has options selected through bits in

the CPU Core Control register (CORCON), as listed

below:

• Fractional or integer DSP multiply (IF)

• Signed, unsigned, or mixed-sign DSP multiply (US)

• Conventional or convergent rounding (RND)

• Automatic saturation on/off for ACCA (SATA)

• Automatic saturation on/off for ACCB (SATB)

• Automatic saturation on/off for writes to data

memory (SATDW)

• Accumulator Saturation mode selection

(ACCSAT)

4.0 MEMORY ORGANIZATION

The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/

50X, and PIC24EPXXXGP/MC20X architecture

features separate program and data memory spaces

and buses. This architecture also allows the direct

access of program memory from the data space during

code execution.

4.1 Program Address Space

The program address memory space of the

dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/50X,

and PIC24EPXXXGP/MC20X devices is 4M

instructions. The space is addressable by a 24-bit

value derived either from the 23-bit PC during program

execution, or from table operation or data space

remapping as described in Section 4.8 “Interfacing

Program and Data Memory Spaces”.

User application access to the program memory space

is restricted to the lower half of the address range

(0x000000 to 0x7FFFFF). The exception is the use of

TBLRD operations, which use TBLPAG<7> to read

Device ID sections of the configuration memory space.

The program memory maps, which are presented by

device family and memory size, are shown in

Figure 4-1 through Figure 4-5.

4.1.1 PROGRAM MEMORY

ORGANIZATION

The program memory space is organized in word-

addressable blocks. Although it is treated as 24 bits

wide, it is more appropriate to think of each address of

the program memory as a lower and upper word, with

the upper byte of the upper word being unimplemented.

The lower word always has an even address, while the

upper word has an odd address (Figure 4-6).

Program memory addresses are always word-aligned

on the lower word, and addresses are incremented or

decremented by two during code execution. This

arrangement provides compatibility with data memory

space addressing and makes data in the program

memory space accessible.

4.1.2 INTERRUPT AND TRAP VECTORS

All dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/

50X, and PIC24EPXXXGP/MC20X devices reserve

the addresses between 0x000000 and 0x000200 for

hard-coded program execution vectors. A hardware

Reset vector is provided to redirect code execution

from the default value of the PC on device Reset to the

actual start of code. A GOTO instruction is programmed

by the user application at address 0x000000 of Flash

memory, with the actual address for the start of code at

address 0x000002 of Flash memory.

A more detailed discussion of the interrupt vector

tables is provided in Section 7.1 “Interrupt Vector

Table”.

4.2 Data Address Space

The dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/

50X, and PIC24EPXXXGP/MC20X CPU has a

separate 16-bit wide data memory space. The data

space is accessed using separate Address Generation

Units (AGUs) for read and write operations. The data

memory maps, which are presented by device family

and memory size, are shown in Figure 4-7 through

Figure 4-16.

All Effective Addresses (EAs) in the data memory space

are 16 bits wide and point to bytes within the data space.

This arrangement gives a base data space address

range of 8 Kbytes or 4K words.

The base data space address is used in conjunction with

a read or write page register (DSRPAG or DSWPAG) to

form an extended data space, which has a total address

range of 16 MB.

dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/50X,

and PIC24EPXXXGP/MC20X devices implement up to

56 Kbytes of data memory. If an EA point to a location

outside of this area, an all-zero word or byte is returned.

4.2.1 DATA SPACE WIDTH

The data memory space is organized in byte

addressable, 16-bit wide blocks. Data is aligned in data

memory and registers as 16-bit words, but all data

space EAs resolve to bytes. The Least Significant

Bytes (LSBs) of each word have even addresses, while

the Most Significant Bytes (MSBs) have odd

addresses.

4.2.2 DATA MEMORY ORGANIZATION

AND ALIGNMENT

To maintain backward compatibility with PIC® MCU

devices and improve data space memory usage

efficiency, the dsPIC33EPXXXGP50X,

dsPIC33EPXXXMC20X/50X, and PIC24EPXXXGP/

MC20X instruction set supports both word and byte

operations. As a consequence of byte accessibility, all

effective address calculations are internally scaled to

step through word-aligned memory. For example, the

core recognizes that Post-Modified Register Indirect

Addressing mode [Ws++] results in a value of Ws + 1

for byte operations and Ws + 2 for word operations.

A data byte read, reads the complete word that

contains the byte, using the LSb of any EA to determine

which byte to select. The selected byte is placed onto

the LSB of the data path. That is, data memory and

registers are organized as two parallel byte-wide

entities with shared (word) address decode but

separate write lines. Data byte writes only write to the

corresponding side of the array or register that matches

the byte address.

All word accesses must be aligned to an even address.

Misaligned word data fetches are not supported, so

care must be taken when mixing byte and word

operations, or translating from 8-bit MCU code. If a

misaligned read or write is attempted, an address error

trap is generated. If the error occurred on a read, the

instruction underway is completed. If the error occurred

on a write, the instruction is executed but the write does

not occur. In either case, a trap is then executed,

allowing the system and/or user application to examine

the machine state prior to execution of the address

Fault.

All byte loads into any W register are loaded into the

LSB. The MSB is not modified.

A Sign-Extend instruction (SE) is provided to allow user

applications to translate 8-bit signed data to 16-bit

signed values. Alternatively, for 16-bit unsigned data,

user applications can clear the MSB of any W register

by executing a Zero-Extend (ZE) instruction on the

appropriate address.

4.2.3 SFR SPACE

The first 4 Kbytes of the Near Data Space, from 0x0000

to 0x0FFF, is primarily occupied by Special Function

Registers (SFRs). These are used by the

dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/50X,

and PIC24EPXXXGP/MC20X core and peripheral

modules for controlling the operation of the device.

SFRs are distributed among the modules that they

control, and are generally grouped together by module.

Much of the SFR space contains unused addresses;

these are read as ‘0’.

4.2.4 NEAR DATA SPACE

The 8 Kbyte area between 0x0000 and 0x1FFF is

referred to as the near data space. Locations in this

space are directly addressable through a 13-bit abso-

lute address field within all memory direct instructions.

Additionally, the whole data space is addressable using

MOV instructions, which support Memory Direct

Addressing mode with a 16-bit address field, or by

using Indirect Addressing mode using a working

Note: The actual set of peripheral features and

interrupts varies by the device. Refer to

the corresponding device tables and

pinout diagrams for device-specific

information.

4.2.5 X AND Y DATA SPACES

The dsPIC33EPXXXMC20X/50X and

dsPIC33EPXXXGP50X core has two data spaces, X

and Y. These data spaces can be considered either

separate (for some DSP instructions), or as one unified

linear address range (for MCU instructions). The data

spaces are accessed using two Address Generation

Units (AGUs) and separate data paths. This feature

allows certain instructions to concurrently fetch two

words from RAM, thereby enabling efficient execution

of DSP algorithms such as Finite Impulse Response

(FIR) filtering and Fast Fourier Transform (FFT).

The X data space is used by all instructions and

supports all addressing modes. X data space has

separate read and write data buses. The X read data

bus is the read data path for all instructions that view

data space as combined X and Y address space. It is

also the X data prefetch path for the dual operand DSP

instructions (MAC class).

The Y data space is used in concert with the X data

space by the MAC class of instructions (CLR, ED,

EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to provide

two concurrent data read paths.

Both the X and Y data spaces support Modulo

Addressing mode for all instructions, subject to

addressing mode restrictions. Bit-Reversed

Addressing mode is only supported for writes to X data

space. Modulo Addressing and Bit-Reversed

Addressing are not present in PIC24EPXXXGP/

MC20X devices.

All data memory writes, including in DSP instructions,

view data space as combined X and Y address space.

The boundary between the X and Y data spaces is

device-dependent and is not user-programmable.
