PIC10F200/202/204/206
1.0 GENERAL DESCRIPTION
The PIC10F200/202/204/206 devices from Microchip
Technology are low-cost, high-performance, 8-bit, fully-
static, Flash-based CMOS microcontrollers. They
employ a RISC architecture with only 33 single-word/
single-cycle instructions. All instructions are single
cycle (1 s) except for program branches, which take
two cycles. The PIC10F200/202/204/206 devices
deliver performance in an order of magnitude higher
than their competitors in the same price category. The
12-bit wide instructions are highly symmetrical, result-
ing in a typical 2:1 code compression over other 8-bit
microcontrollers in its class. The easy-to-use and easy
to remember instruction set reduces development time
significantly.
The PIC10F200/202/204/206 products are equipped
with special features that reduce system cost and
power requirements. The Power-on Reset (POR) and
Device Reset Timer (DRT) eliminate the need for exter-
nal Reset circuitry. INTRC Internal Oscillator mode is
provided, thereby preserving the limited number of I/O
available. Power-Saving Sleep mode, Watchdog Timer
and code protection features improve system cost,
power and reliability.
The PIC10F200/202/204/206 devices are available in
cost-effective Flash, which is suitable for production in
any volume. The customer can take full advantage of
Microchip’s price leadership in Flash programmable
microcontrollers, while benefiting from the Flash
programmable flexibility.
The PIC10F200/202/204/206 products are supported
by a full-featured macro assembler, a software simula-
tor, an in-circuit debugger, a ‘C’ compiler, a low-cost
development programmer and a full featured program-
mer. All the tools are supported on IBM® PC and
compatible machines.
1.1 Applications
The PIC10F200/202/204/206 devices fit in applications
ranging from personal care appliances and security
systems to low-power remote transmitters/receivers.
The Flash technology makes customizing application
programs (transmitter codes, appliance settings,
receiver frequencies, etc.) extremely fast and conve-
nient. The small footprint packages, for through hole or
surface mounting, make these microcontrollers well
suited for applications with space limitations. Low cost,
low power, high performance, ease-of-use and I/O
flexibility make the PIC10F200/202/204/206 devices
very versatile even in areas where no microcontroller
use has been considered before (e.g., timer functions,
logic and PLDs in larger systems and coprocessor
applications).

2.1 Quick Turn Programming (QTP)
Devices
Microchip offers a QTP programming service for
factory production orders. This service is made
available for users who choose not to program
medium-to-high quantity units and whose code
patterns have stabilized. The devices are identical to
the Flash devices but with all Flash locations and fuse
options already programmed by the factory. Certain
code and prototype verification procedures do apply
before production shipments are available. Please
contact your local Microchip Technology sales office for
more details.
2.2 Serialized Quick Turn
ProgrammingSM (SQTPSM) Devices
Microchip offers a unique programming service, where
a few user-defined locations in each device are
programmed with different serial numbers. The serial
numbers may be random, pseudo-random or
sequential.
Serial programming allows each device to have a
unique number, which can serve as an entry code,
password or ID number.

PIC10F200/202/204/206
3.0 ARCHITECTURAL OVERVIEW
The high performance of the PIC10F200/202/204/206
devices can be attributed to a number of architectural
features commonly found in RISC microprocessors. To
begin with, the PIC10F200/202/204/206 devices use a
Harvard architecture in which program and data are
accessed on separate buses. This improves band-
width over traditional von Neumann architectures
where program and data are fetched on the same bus.
Separating program and data memory further allows
instructions to be sized differently than the 8-bit wide
data word. Instruction opcodes are 12 bits wide,
making it possible to have all single-word instructions.
A 12-bit wide program memory access bus fetches a
12-bit instruction in a single cycle. A two-stage pipeline
overlaps fetch and execution of instructions.
Consequently, all instructions (33) execute in a single
cycle (1 s @ 4 MHz) except for program branches.
The table below lists program memory (Flash) and data
memory (RAM) for the PIC10F200/202/204/206
devices.
TABLE 3-1: PIC10F2XX MEMORY
The PIC10F200/202/204/206 devices can directly or
indirectly address its register files and data memory. All
Special Function Registers (SFR), including the PC,
are mapped in the data memory. The PIC10F200/202/
204/206 devices have a highly orthogonal
(symmetrical) instruction set that makes it possible to
carry out any operation, on any register, using any
addressing mode. This symmetrical nature and lack of
“special optimal situations” make programming with the
PIC10F200/202/204/206 devices simple, yet efficient.
In addition, the learning curve is reduced significantly.
The PIC10F200/202/204/206 devices contain an 8-bit
ALU and working register. The ALU is a general
purpose arithmetic unit. It performs arithmetic and
Boolean functions between data in the working register
and any register file.
The ALU is 8 bits wide and capable of addition, subtrac-
tion, shift and logical operations. Unless otherwise
mentioned, arithmetic operations are two’s comple-
ment in nature. In two-operand instructions, one oper-
and is typically the W (working) register. The other
operand is either a file register or an immediate con-
stant. In single operand instructions, the operand is
either the W register or a file register.
The W register is an 8-bit working register used for ALU
operations. It is not an addressable register.
Depending on the instruction executed, the ALU may
affect the values of the Carry (C), Digit Carry (DC) and
Zero (Z) bits in the STATUS register. The C and DC bits
operate as a borrow and digit borrow out bit, respec-
tively, in subtraction. See the SUBWF and ADDWF
instructions for examples.
A simplified block diagram is shown in Figure 3-1 and
Figure 3-2, with the corresponding device pins
described in Table 3-2.

3.1 Clocking Scheme/Instruction
Cycle
The clock is internally divided by four to generate four
non-overlapping quadrature clocks, namely Q1, Q2,
Q3 and Q4. Internally, the PC is incremented every Q1
and the instruction is fetched from program memory
and latched into the instruction register in Q4. It is
decoded and executed during the following Q1 through
Q4. The clocks and instruction execution flow is shown
in Figure 3-3 and Example 3-1.
3.2 Instruction Flow/Pipelining
An instruction cycle consists of four Q cycles (Q1, Q2,
Q3 and Q4). The instruction fetch and execute are
pipelined such that fetch takes one instruction cycle,
while decode and execute take another instruction
cycle. However, due to the pipelining, each instruction
effectively executes in one cycle. If an instruction
causes the PC to change (e.g., GOTO), then two cycles
are required to complete the instruction (Example 3-1).
A fetch cycle begins with the PC incrementing in Q1.
In the execution cycle, the fetched instruction is latched
into the Instruction Register (IR) in cycle Q1. This
instruction is then decoded and executed during the
Q2, Q3 and Q4 cycles. Data memory is read during Q2
(operand read) and written during Q4 (destination
write).

4.0 MEMORY ORGANIZATION
The PIC10F200/202/204/206 memories are organized
into program memory and data memory. Data memory
banks are accessed using the File Select Register
(FSR).
4.1 Program Memory Organization for
the PIC10F200/204
The PIC10F200/204 devices have a 9-bit Program
Counter (PC) capable of addressing a 512 x 12
program memory space.
Only the first 256 x 12 (0000h-00FFh) for the
PIC10F200/204 are physically implemented (see
Figure 4-1). Accessing a location above these
boundaries will cause a wraparound within the first
256 x 12 space (PIC10F200/204). The effective
Reset vector is at 0000h (see Figure 4-1). Location
00FFh (PIC10F200/204) contains the internal clock
oscillator calibration value. This value should never
be overwritten.

the PIC10F202/206
The PIC10F202/206 devices have a 10-bit Program
Counter (PC) capable of addressing a 1024 x 12
program memory space.
Only the first 512 x 12 (0000h-01FFh) for the

4.3 Data Memory Organization
Data memory is composed of registers or bytes of
RAM. Therefore, data memory for a device is specified
by its register file. The register file is divided into two
functional groups: Special Function Registers (SFR)
and General Purpose Registers (GPR).
The Special Function Registers include the TMR0 reg-
ister, the Program Counter (PCL), the STATUS register,
the I/O register (GPIO) and the File Select Register
(FSR). In addition, Special Function Registers are used
to control the I/O port configuration and prescaler
options.
The General Purpose registers are used for data and
control information under command of the instructions.
For the PIC10F200/204, the register file is composed of
7 Special Function registers and 16 General Purpose
registers (see Figure 4-3 and Figure 4-4).
For the PIC10F202/206, the register file is composed of
8 Special Function registers and 24 General Purpose
registers (see Figure 4-4).
4.3.1 GENERAL PURPOSE REGISTER
FILE
The General Purpose Register file is accessed, either
directly or indirectly, through the File Select Register
(FSR). See Section 4.9 “Indirect Data Addressing:
INDF and FSR Registers”.

4.3.2 SPECIAL FUNCTION REGISTERS
The Special Function Registers (SFRs) are registers
used by the CPU and peripheral functions to control the
operation of the device (Table 4-1).
The Special Function Registers can be classified into
two sets. The Special Function Registers associated
with the “core” functions are described in this section.
Those related to the operation of the peripheral
features are described in the section for each
peripheral feature.

4.4 STATUS Register
This register contains the arithmetic status of the ALU,
the Reset status and the page preselect bit.
The STATUS register can be the destination for any
instruction, as with any other register. If the STATUS
register is the destination for an instruction that affects
the Z, DC or C bits, then the write to these three bits is
disabled. These bits are set or cleared according to the
device logic. Furthermore, the TO and PD bits are not
writable. Therefore, the result of an instruction with the
STATUS register as destination may be different than
intended.
For example, CLRF STATUS, will clear the upper three
bits and set the Z bit. This leaves the STATUS register
as 000u u1uu (where u = unchanged).
Therefore, it is recommended that only BCF, BSF and
MOVWF instructions be used to alter the STATUS regis-
ter. These instructions do not affect the Z, DC or C bits
from the STATUS register. For other instructions which
do affect Status bits, see Section 10.0 “Instruction
Set Summary”.

4.5 OPTION Register
The OPTION register is a 8-bit wide, write-only register,
which contains various control bits to configure the
Timer0/WDT prescaler and Timer0.
By executing the OPTION instruction, the contents of
the W register will be transferred to the OPTION regis-
ter. A Reset sets the OPTION<7:0> bits.
Note: If TRIS bit is set to ‘0’, the wake-up on
change and pull-up functions are disabled
for that pin (i.e., note that TRIS overrides
Option control of GPPU and GPWU).
Note: If the T0CS bit is set to ‘1’, it will override
the TRIS function on the T0CKI pin.

4.6 OSCCAL Register
The Oscillator Calibration (OSCCAL) register is used to
calibrate the internal precision 4 MHz oscillator. It
contains seven bits for calibration.
After you move in the calibration constant, do not
change the value. See Section 9.2.2 “Internal 4 MHz
Oscillator”.
Note: Erasing the device will also erase the pre-
programmed internal calibration value for
the internal oscillator. The calibration
value must be read prior to erasing the
part so it can be reprogrammed correctly
later.

4.7 Program Counter
As a program instruction is executed, the Program
Counter (PC) will contain the address of the next
program instruction to be executed. The PC value is
increased by one every instruction cycle, unless an
instruction changes the PC.
For a GOTO instruction, bits 8:0 of the PC are provided
by the GOTO instruction word. The Program Counter
Low (PCL) is mapped to PC<7:0>.
For a CALL instruction, or any instruction where the
PCL is the destination, bits 7:0 of the PC again are pro-
vided by the instruction word. However, PC<8> does
not come from the instruction word, but is always
cleared (Figure 4-5).
Instructions where the PCL is the destination, or modify
PCL instructions, include MOVWF PC, ADDWF PC and
BSF PC,5.
FIGURE 4-5: LOADING OF PC
BRANCH INSTRUCTIONS
4.7.1 EFFECTS OF RESET
The PC is set upon a Reset, which means that the PC
addresses the last location in program memory (i.e.,
the oscillator calibration instruction). After executing
MOVLW XX, the PC will roll over to location 0000h and
begin executing user code.
4.8 Stack
The PIC10F200/204 devices have a 2-deep, 8-bit wide
hardware PUSH/POP stack.
The PIC10F202/206 devices have a 2-deep, 9-bit wide
hardware PUSH/POP stack.
A CALL instruction will PUSH the current value of Stack 1
into Stack 2 and then PUSH the current PC value,
incremented by one, into Stack Level 1. If more than two
sequential CALLs are executed, only the most recent two
return addresses are stored.
A RETLW instruction will POP the contents of Stack
Level 1 into the PC and then copy Stack Level 2
contents into level 1. If more than two sequential
RETLWs are executed, the stack will be filled with the
address previously stored in Stack Level 2.
Note: Because PC<8> is cleared in the CALL
instruction or any modify PCL instruction,
all subroutine calls or computed jumps are
limited to the first 256 locations of any
program memory page (512 words long).

Note 1: The W register will be loaded with the lit-

2: There are no Status bits to indicate stack
overflows or stack underflow conditions.
3: There are no instruction mnemonics
called PUSH or POP. These are actions
that occur from the execution of the CALL
and RETLW instructions.

4.9 Indirect Data Addressing: INDF
and FSR Registers
The INDF register is not a physical register. Addressing
INDF actually addresses the register whose address is
contained in the FSR register (FSR is a pointer). This is
indirect addressing.
4.10 Indirect Addressing
• Register file 09 contains the value 10h
• Register file 0A contains the value 0Ah
• Load the value 09 into the FSR register
• A read of the INDF register will return the value
of 10h
• Increment the value of the FSR register by one
(FSR = 0A)
• A read of the INDR register now will return the
value of 0Ah.
Reading INDF itself indirectly (FSR = 0) will produce
00h. Writing to the INDF register indirectly results in a
no operation (although Status bits may be affected).
A simple program to clear RAM locations 10h-1Fh
using indirect addressing is shown in Example 4-1.
EXAMPLE 4-1: HOW TO CLEAR RAM
USING INDIRECT
ADDRESSING
The FSR is a 5-bit wide register. It is used in conjunc-
tion with the INDF register to indirectly address the data
memory area.
The FSR<4:0> bits are used to select data memory
addresses 00h to 1Fh.

5.0 I/O PORT
As with any other register, the I/O register(s) can be
written and read under program control. However, read
instructions (e.g., MOVF GPIO, W) always read the I/O
pins independent of the pin’s Input/Output modes. On
Reset, all I/O ports are defined as input (inputs are at
high-impedance) since the I/O control registers are all
set.
5.1 GPIO
GPIO is an 8-bit I/O register. Only the low-order 4 bits
are used (GP<3:0>). Bits 7 through 4 are unimple-
mented and read as ‘0’s. Please note that GP3 is an
input-only pin. Pins GP0, GP1 and GP3 can be config-
ured with weak pull-ups and also for wake-up on
change. The wake-up on change and weak pull-up
functions are not pin selectable. If GP3/MCLR is config-
ured as MCLR, weak pull-up is always on and wake-up
on change for this pin is not enabled.
5.2 TRIS Registers
The Output Driver Control register is loaded with the
contents of the W register by executing the TRIS f
instruction. A ‘1’ from a TRIS register bit puts the corre-
sponding output driver in a High-Impedance mode. A
‘0’ puts the contents of the output data latch on the
selected pins, enabling the output buffer. The excep-
tions are GP3, which is input-only and the GP2/T0CKI/
COUT/FOSC4 pin, which may be controlled by various
registers. See Table 5-1.
The TRIS registers are “write-only” and are set (output
drivers disabled) upon Reset.
TABLE 5-1: ORDER OF PRECEDENCE
FOR PIN FUNCTIONS
5.3 I/O Interfacing
The equivalent circuit for an I/O port pin is shown in
Figure 5-1. All port pins, except GP3 which is input-
only, may be used for both input and output operations.
For input operations, these ports are non-latching. Any
input must be present until read by an input instruction
(e.g., MOVF GPIO, W). The outputs are latched and
remain unchanged until the output latch is rewritten. To
use a port pin as output, the corresponding direction
control bit in TRIS must be cleared (= 0). For use as an
input, the corresponding TRIS bit must be set. Any I/O
pin (except GP3) can be programmed individually as
input or output.
FIGURE 5-1: PIC10F200/202/204/206
EQUIVALENT CIRCUIT
FOR A SINGLE I/O PIN
Note: A read of the ports reads the pins, not the
output data latches. That is, if an output
driver on a pin is enabled and driven high,
but the external system is holding it low, a
read of the port will indicate that the pin is
low.

TABLE 5-2: SUMMARY OF PORT REGISTERS
5.4 I/O Programming Considerations
5.4.1 BIDIRECTIONAL I/O PORTS
Some instructions operate internally as read followed
by write operations. The BCF and BSF instructions, for
example, read the entire port into the CPU, execute the
bit operation and rewrite the result. Caution must be
used when these instructions are applied to a port
where one or more pins are used as input/outputs. For
example, a BSF operation on bit 2 of GPIO will cause
all eight bits of GPIO to be read into the CPU, bit 2 to
be set and the GPIO value to be written to the output
latches. If another bit of GPIO is used as a bidirectional
I/O pin (say bit 0), and it is defined as an input at this
time, the input signal present on the pin itself would be
read into the CPU and rewritten to the data latch of this
particular pin, overwriting the previous content. As long
as the pin stays in the Input mode, no problem occurs.
However, if bit 0 is switched into Output mode later on,
the content of the data latch may now be unknown.
Example 5-1 shows the effect of two sequential
Read-Modify-Write instructions (e.g., BCF, BSF, etc.)
on an I/O port.
A pin actively outputting a high or a low should not be
driven from external devices at the same time in order
to change the level on this pin (“wired OR”, “wired
AND”). The resulting high output currents may damage
the chip.
EXAMPLE 5-1: READ-MODIFY-WRITE
INSTRUCTIONS ON AN
I/O PORT
5.4.2 SUCCESSIVE OPERATIONS ON
I/O PORTS
The actual write to an I/O port happens at the end of an
instruction cycle, whereas for reading, the data must be
valid at the beginning of the instruction cycle (Figure 5-2).
Therefore, care must be exercised if a write followed by
a read operation is carried out on the same I/O port. The
sequence of instructions should allow the pin voltage to
stabilize (load dependent) before the next instruction
causes that file to be read into the CPU. Otherwise, the
previous state of that pin may be read into the CPU rather
than the new state. When in doubt, it is better to separate
these instructions with a NOP or another instruction not
accessing this I/O port.

6.0 TIMER0 MODULE AND TMR0
REGISTER (PIC10F200/202)
The Timer0 module has the following features:
• 8-bit timer/counter register, TMR0
• Readable and writable
• 8-bit software programmable prescaler
• Internal or external clock select:
- Edge select for external clock
Figure 6-1 is a simplified block diagram of the Timer0
module.
Timer mode is selected by clearing the T0CS bit
(OPTION<5>). In Timer mode, the Timer0 module will
increment every instruction cycle (without prescaler). If
TMR0 register is written, the increment is inhibited for
the following two cycles (Figure 6-2 and Figure 6-3).
The user can work around this by writing an adjusted
value to the TMR0 register.
Counter mode is selected by setting the T0CS bit
(OPTION<5>). In this mode, Timer0 will increment
either on every rising or falling edge of pin T0CKI. The
T0SE bit (OPTION<4>) determines the source edge.
Clearing the T0SE bit selects the rising edge. Restric-
tions on the external clock input are discussed in detail
in Section 6.1 “Using Timer0 with an External Clock
(PIC10F200/202)”.
The prescaler may be used by either the Timer0
module or the Watchdog Timer, but not both. The
prescaler assignment is controlled in software by the
control bit, PSA (OPTION<3>). Clearing the PSA bit
will assign the prescaler to Timer0. The prescaler is not
readable or writable. When the prescaler is assigned to
the Timer0 module, prescale values of 1:2, 1:4, 1:256
are selectable. Section 6.2 “Prescaler” details the
operation of the prescaler.
A summary of registers associated with the Timer0
module is found in Table 6-1.

TABLE 6-1: REGISTERS ASSOCIATED WITH TIMER0
6.1 Using Timer0 with an External
Clock (PIC10F200/202)
When an external clock input is used for Timer0, it must
meet certain requirements. The external clock require-
ment is due to internal phase clock (TOSC) synchroniza-
tion. Also, there is a delay in the actual incrementing of
Timer0 after synchronization.
6.1.1 EXTERNAL CLOCK
SYNCHRONIZATION
When no prescaler is used, the external clock input is
the same as the prescaler output. The synchronization
of T0CKI with the internal phase clocks is accom-
plished by sampling the prescaler output on the Q2 and
Q4 cycles of the internal phase clocks (Figure 6-4).
Therefore, it is necessary for T0CKI to be high for at
least 2 T
OSC (and a small RC delay of 2 Tt0H) and low
for at least 2 T
OSC (and a small RC delay of 2 Tt0H).
Refer to the electrical specification of the desired
device.
When a prescaler is used, the external clock input is
divided by the asynchronous ripple counter-type
prescaler, so that the prescaler output is symmetrical.
For the external clock to meet the sampling require-
ment, the ripple counter must be taken into account.
Therefore, it is necessary for T0CKI to have a period of
at least 4 TOSC (and a small RC delay of 4 Tt0H) divided
by the prescaler value. The only requirement on T0CKI
high and low time is that they do not violate the
minimum pulse width requirement of Tt0H. Refer to
parameters 40, 41 and 42 in the electrical specification
of the desired device.

6.1.2 TIMER0 INCREMENT DELAY
Since the prescaler output is synchronized with the
internal clocks, there is a small delay from the time the
external clock edge occurs to the time the Timer0
module is actually incremented. Figure 6-4 shows the
delay from the external clock edge to the timer
incrementing.
FIGURE 6-4: TIMER0 TIMING WITH EXTERNAL CLOCK
6.2 Prescaler
An 8-bit counter is available as a prescaler for the
Timer0 module or as a postscaler for the Watchdog
Timer (WDT), respectively (see Section 9.6 “Watch-
dog Timer (WDT)”). For simplicity, this counter is
being referred to as “prescaler” throughout this data
sheet.
The PSA and PS<2:0> bits (OPTION<3:0>) determine
prescaler assignment and prescale ratio.
When assigned to the Timer0 module, all instructions
writing to the TMR0 register (e.g., CLRF 1, MOVWF 1,
BSF 1,x, etc.) will clear the prescaler. When assigned
to WDT, a CLRWDT instruction will clear the prescaler
along with the WDT. The prescaler is neither readable
nor writable. On a Reset, the prescaler contains all ‘0’s.
6.2.1 SWITCHING PRESCALER
ASSIGNMENT
The prescaler assignment is fully under software
control (i.e., it can be changed “on-the-fly” during pro-
gram execution). To avoid an unintended device Reset,
the following instruction sequence (Example 6-1) must
be executed when changing the prescaler assignment
from Timer0 to the WDT.

3: The arrows indicate the points in time where sampling occurs.
Note: The prescaler may be used by either the

Thus, a prescaler assignment for the

prescaler for the WDT and vice versa.

7.0 TIMER0 MODULE AND TMR0
REGISTER (PIC10F204/206)
The Timer0 module has the following features:
• 8-bit timer/counter register, TMR0
• Readable and writable
• 8-bit software programmable prescaler
• Internal or external clock select:
- Edge select for external clock
- External clock from either the T0CKI pin or
from the output of the comparator
Figure 7-1 is a simplified block diagram of the Timer0
module.
Timer mode is selected by clearing the T0CS bit
(OPTION<5>). In Timer mode, the Timer0 module will
increment every instruction cycle (without prescaler). If
TMR0 register is written, the increment is inhibited for
the following two cycles (Figure 7-2 and Figure 7-3).
The user can work around this by writing an adjusted
value to the TMR0 register.
There are two types of Counter mode. The first Counter
mode uses the T0CKI pin to increment Timer0. It is
selected by setting the T0CS bit (OPTION<5>), setting
the CMPT0CS bit (CMCON0<4>) and setting the
COUTEN bit (CMCON0<6>). In this mode, Timer0 will
increment either on every rising or falling edge of pin
T0CKI. The T0SE bit (OPTION<4>) determines the
source edge. Clearing the T0SE bit selects the rising
edge. Restrictions on the external clock input are
discussed in detail in Section 7.1 “Using Timer0 with
an External Clock (PIC10F204/206)”.
The second Counter mode uses the output of the com-
parator to increment Timer0. It can be entered in two
different ways. The first way is selected by setting the
T0CS bit (OPTION<5>) and clearing the CMPT0CS bit
(CMCON<4>); (COUTEN [CMCON<6>]) does not
affect this mode of operation. This enables an internal
connection between the comparator and the Timer0.
The second way is selected by setting the T0CS bit
(OPTION<5>), setting the CMPT0CS bit
(CMCON0<4>) and clearing the COUTEN bit
(CMCON0<6>). This allows the output of the compara-
tor onto the T0CKI pin, while keeping the T0CKI input
active. Therefore, any comparator change on the
COUT pin is fed back into the T0CKI input. The T0SE
bit (OPTION<4>) determines the source edge. Clear-
ing the T0SE bit selects the rising edge. Restrictions on
the external clock input as discussed in Section 7.1
“Using Timer0 with an External Clock (PIC10F204/
206)”
The prescaler may be used by either the Timer0
module or the Watchdog Timer, but not both. The
prescaler assignment is controlled in software by the
control bit, PSA (OPTION<3>). Clearing the PSA bit
will assign the prescaler to Timer0. The prescaler is not
readable or writable. When the prescaler is assigned to
the Timer0 module, prescale values of 1:2, 1:4,...,
1:256 are selectable. Section 7.2 “Prescaler” details
the operation of the prescaler.
A summary of registers associated with the Timer0
module is found in Table 7-1.

7.1 Using Timer0 with an External
Clock (PIC10F204/206)
When an external clock input is used for Timer0, it must
meet certain requirements. The external clock require-
ment is due to internal phase clock (TOSC) synchroniza-
tion. Also, there is a delay in the actual incrementing of
Timer0 after synchronization.
7.1.1 EXTERNAL CLOCK
SYNCHRONIZATION
When no prescaler is used, the external clock input is
the same as the prescaler output. The synchronization
of an external clock with the internal phase clocks is
accomplished by sampling the prescaler output on the
Q2 and Q4 cycles of the internal phase clocks
(Figure 7-4). Therefore, it is necessary for T0CKI or the
comparator output to be high for at least 2 TOSC (and a
small RC delay of 2 Tt0H) and low for at least 2 T
OSC
(and a small RC delay of 2 Tt0H). Refer to the electrical
specification of the desired device.
When a prescaler is used, the external clock input is
divided by the asynchronous ripple counter type
prescaler, so that the prescaler output is symmetrical.
For the external clock to meet the sampling require-
ment, the ripple counter must be taken into account.
Therefore, it is necessary for T0CKI or the comparator
output to have a period of at least 4 TOSC (and a small
RC delay of 4 Tt0H) divided by the prescaler value. The
only requirement on T0CKI or the comparator output
high and low time is that they do not violate the
minimum pulse width requirement of Tt0H. Refer to
parameters 40, 41 and 42 in the electrical specification
of the desired device.

8.1 Comparator Configuration
The on-board comparator inputs, (GP0/CIN+, GP1/
CIN-), as well as the comparator output (GP2/COUT),
are steerable. The CMCON0, OPTION and TRIS
registers are used to steer these pins (see Figure 8-1).
If the Comparator mode is changed, the comparator
output level may not be valid for the specified mode
change delay shown in Table 12-1.

8.2 Comparator Operation
A single comparator is shown in Figure 8-2 along with
the relationship between the analog input levels and
the digital output. When the analog input at VIN+ is less
than the analog input VIN-, the output of the comparator
is a digital low level. When the analog input at VIN+ is
greater than the analog input VIN-, the output of the
comparator is a digital high level. The shaded areas of
the output of the comparator in Figure 8-2 represent
the uncertainty due to input offsets and response time.
See Table 12-1 for Common Mode Voltage.
FIGURE 8-2: SINGLE COMPARATOR
8.3 Comparator Reference
An internal reference signal may be used depending on
the comparator operating mode. The analog signal that
is present at VIN- is compared to the signal at VIN+ and
the digital output of the comparator is adjusted
accordingly (Figure 8-2). Please see Table 12-1 for
internal reference specifications.
8.4 Comparator Response Time
Response time is the minimum time, after selecting a
new reference voltage or input source, before the
comparator output is to have a valid level. If the com-
parator inputs are changed, a delay must be used to
allow the comparator to settle to its new state. Please
see Table 12-1 for comparator response time
specifications.
8.5 Comparator Output
The comparator output is read through CMCON0
register. This bit is read-only. The comparator output
may also be used internally, see Figure 8-1.
8.6 Comparator Wake-up Flag
The comparator wake-up flag is set whenever all of the
following conditions are met:
•CWU = 0 (CMCON0<0>)
• CMCON0 has been read to latch the last known
state of the CMPOUT bit (MOVF CMCON0, W)
• Device is in Sleep
• The output of the comparator has changed state
The wake-up flag may be cleared in software or by
another device Reset.
8.7 Comparator Operation During
Sleep
When the comparator is active and the device is placed
in Sleep mode, the comparator remains active. While
the comparator is powered-up, higher Sleep currents
than shown in the power-down current specification will
occur. To minimize power consumption while in Sleep
mode, turn off the comparator before entering Sleep.
8.8 Effects of a Reset
A Power-on Reset (POR) forces the CMCON0 register
to its Reset state. This forces the Comparator module
to be in the comparator Reset mode. This ensures that
all potential inputs are analog inputs. Device current is
minimized when analog inputs are present at Reset
time. The comparator will be powered-down during the
Reset interval.
8.9 Analog Input Connection
Considerations
A simplified circuit for an analog input is shown in
Figure 8-3. Since the analog pins are connected to a
digital output, they have reverse biased diodes to VDD
and VSS. The analog input therefore, must be between
VSS and VDD. If the input voltage deviates from this
range by more than 0.6V in either direction, one of the
diodes is forward biased and a latch-up may occur. A
maximum source impedance of 10 k is
recommended for the analog sources. Any external
component connected to an analog input pin, such as
a capacitor or a Zener diode, should have very little
leakage current.

9.0 SPECIAL FEATURES OF THE
CPU
What sets a microcontroller apart from other proces-
sors are special circuits that deal with the needs of real-
time applications. The PIC10F200/202/204/206
microcontrollers have a host of such features intended
to maximize system reliability, minimize cost through
elimination of external components, provide power-
saving operating modes and offer code protection.
These features are:
• Reset:
- Power-on Reset (POR)
- Device Reset Timer (DRT)
- Watchdog Timer (WDT)
- Wake-up from Sleep on pin change
- Wake-up from Sleep on comparator change
• Sleep
• Code Protection
• ID Locations
• In-Circuit Serial Programming™
•Clock Out
The PIC10F200/202/204/206 devices have a Watch-
dog Timer, which can be shut off only through Configu-
ration bit WDTE. It runs off of its own RC oscillator for
added reliability. When using INTRC, there is an 18 ms
delay only on VDD power-up. With this timer on-chip,
most applications need no external Reset circuitry.
The Sleep mode is designed to offer a very low-current
Power-Down mode. The user can wake-up from Sleep
through a change on input pins, wake-up from
comparator change, or through a Watchdog Timer
time-out.
9.1 Configuration Bits
The PIC10F200/202/204/206 Configuration Words
consist of 12 bits. Configuration bits can be pro-
grammed to select various device configurations. One
bit is the Watchdog Timer enable bit, one bit is the
MCLR enable bit and one bit is for code protection (see
Register 9-1).

9.2 Oscillator Configurations
9.2.1 OSCILLATOR TYPES
The PIC10F200/202/204/206 devices are offered with
Internal Oscillator mode only.
• INTOSC: Internal 4 MHz Oscillator
9.2.2 INTERNAL 4 MHz OSCILLATOR
The internal oscillator provides a 4 MHz (nominal) system
clock (see Section 12.0 “Electrical Characteristics” for
information on variation over voltage and temperature).
In addition, a calibration instruction is programmed into
the last address of memory, which contains the calibra-
tion value for the internal oscillator. This location is
always uncode protected, regardless of the code-pro-
tect settings. This value is programmed as a MOVLW xx
instruction where xx is the calibration value and is
placed at the Reset vector. This will load the W register
with the calibration value upon Reset and the PC will
then roll over to the users program at address 0x000.
The user then has the option of writing the value to the
OSCCAL Register (05h) or ignoring it.
OSCCAL, when written to with the calibration value, will
“trim” the internal oscillator to remove process variation
from the oscillator frequency.
9.3 Reset
The device differentiates between various kinds of
Reset:
• Power-on Reset (POR)
•MCLR
Reset during normal operation
•MCLR
Reset during Sleep
• WDT time-out Reset during normal operation
• WDT time-out Reset during Sleep
• Wake-up from Sleep on pin change
• Wake-up from Sleep on comparator change
Some registers are not reset in any way, they are
unknown on POR and unchanged in any other Reset.
Most other registers are reset to “Reset state” on
Power-on Reset (POR), MCLR, WDT or Wake-up on
pin change Reset during normal operation. They are
not affected by a WDT Reset during Sleep or MCLR
Reset during Sleep, since these Resets are viewed as
resumption of normal operation. The exceptions to this
are TO, PD, GPWUF and CWUF bits. They are set or
cleared differently in different Reset situations. These
bits are used in software to determine the nature of
Reset. See Table 9-1 for a full description of Reset
states of all registers.
TABLE 9-1: RESET CONDITIONS FOR REGISTERS – PIC10F200/202/204/206
Note: Erasing the device will also erase the pre-
programmed internal calibration value for
the internal oscillator. The calibration
value must be read prior to erasing the
part so it can be reprogrammed correctly
later.

TABLE 9-2: RESET CONDITION FOR SPECIAL REGISTERS
9.3.1 MCLR ENABLE
This Configuration bit, when unprogrammed (left in the
‘1’ state), enables the external MCLR function. When
programmed, the MCLR function is tied to the internal
VDD and the pin is assigned to be a I/O. See Figure 9-1.
FIGURE 9-1: MCLR SELECT
9.4 Power-on Reset (POR)
The PIC10F200/202/204/206 devices incorporate an
on-chip Power-on Reset (POR) circuitry, which
provides an internal chip Reset for most power-up
situations.
The on-chip POR circuit holds the chip in Reset until
VDD has reached a high enough level for proper oper-
ation. To take advantage of the internal POR, program
the GP3/MCLR/VPP pin as MCLR and tie through a
resistor to VDD, or program the pin as GP3. An internal
weak pull-up resistor is implemented using a transistor
(refer to Table 12-2 for the pull-up resistor ranges).
This will eliminate external RC components usually
needed to create a Power-on Reset. A maximum rise
time for VDD is specified. See Section 12.0 “Electrical
Characteristics” for details.
When the devices start normal operation (exit the
Reset condition), device operating parameters (volt-
age, frequency, temperature,...) must be met to ensure
operation. If these conditions are not met, the devices
must be held in Reset until the operating parameters
are met.
A simplified block diagram of the on-chip Power-on
Reset circuit is shown in Figure 9-2.
The Power-on Reset circuit and the Device Reset
Timer (see Section 9.5 “Device Reset Timer (DRT)”)
circuit are closely related. On power-up, the Reset latch
is set and the DRT is reset. The DRT timer begins
counting once it detects MCLR to be high. After the
time-out period, which is typically 18 ms, it will reset the
Reset latch and thus end the on-chip Reset signal.
A power-up example where MCLR is held low is shown
in Figure 9-3. VDD is allowed to rise and stabilize before
bringing MCLR high. The chip will actually come out of
Reset TDRT msec after MCLR goes high.
In Figure 9-4, the on-chip Power-on Reset feature is
being used (MCLR and VDD are tied together or the pin
is programmed to be GP3). The VDD is stable before
the Start-up Timer times out and there is no problem in
getting a proper Reset. However, Figure 9-5 depicts a
problem situation where VDD rises too slowly. The time
between when the DRT senses that MCLR is high and
when MCLR and VDD actually reach their full value, is
too long. In this situation, when the Start-up Timer times
out, VDD has not reached the VDD (min) value and the
chip may not function correctly. For such situations, we
recommend that external RC circuits be used to
achieve longer POR delay times (Figure 9-4).
For additional information, refer to Application Notes
AN522 “Power-Up Considerations”, (DS00522) and
AN607 “Power-up Trouble Shooting”, (DS00607).

9.5 Device Reset Timer (DRT)
On the PIC10F200/202/204/206 devices, the DRT runs
any time the device is powered up.
The DRT operates on an internal oscillator. The
processor is kept in Reset as long as the DRT is active.
The DRT delay allows VDD to rise above VDD min. and
for the oscillator to stabilize.
The on-chip DRT keeps the devices in a Reset
condition for approximately 18 ms after MCLR has
reached a logic high (VIH MCLR) level. Programming
GP3/MCLR/VPP as MCLR and using an external RC
network connected to the MCLR input is not required in
most cases. This allows savings in cost-sensitive and/
or space restricted applications, as well as allowing the
use of the GP3/MCLR/VPP pin as a general purpose
input.
The Device Reset Time delays will vary from chip-to-
chip due to VDD, temperature and process variation.
See AC parameters for details.
Reset sources are POR, MCLR, WDT time-out and
wake-up on pin change. See Section 9.9.2 “Wake-up
from Sleep”, Notes 1, 2 and 3.
TABLE 9-3: DRT (DEVICE RESET TIMER
PERIOD)
9.6 Watchdog Timer (WDT)
The Watchdog Timer (WDT) is a free running on-chip
RC oscillator, which does not require any external
components. This RC oscillator is separate from the
internal 4 MHz oscillator. This means that the WDT will
run even if the main processor clock has been stopped,
for example, by execution of a SLEEP instruction.
During normal operation or Sleep, a WDT Reset or
wake-up Reset, generates a device Reset.
The TO bit (STATUS<4>) will be cleared upon a
Watchdog Timer Reset.
The WDT can be permanently disabled by program-
ming the configuration WDTE as a ‘0’ (see Section 9.1
“Configuration Bits”). Refer to the PIC10F200/202/
204/206 Programming Specifications to determine how
to access the Configuration Word.
9.6.1 WDT PERIOD
The WDT has a nominal time-out period of 18 ms, (with
no prescaler). If a longer time-out period is desired, a
prescaler with a division ratio of up to 1:128 can be
assigned to the WDT (under software control) by
writing to the OPTION register. Thus, a time-out period
of a nominal 2.3 seconds can be realized. These peri-
ods vary with temperature, VDD and part-to-part
process variations (see DC specs).
Under worst-case conditions (VDD = Min., Temperature
= Max., max. WDT prescaler), it may take several
seconds before a WDT time-out occurs.
9.6.2 WDT PROGRAMMING
CONSIDERATIONS
The CLRWDT instruction clears the WDT and the
postscaler, if assigned to the WDT, and prevents it from
timing out and generating a device Reset.
The SLEEP instruction resets the WDT and the
postscaler, if assigned to the WDT. This gives the
maximum Sleep time before a WDT wake-up Reset.

9.9 Power-Down Mode (Sleep)
A device may be powered down (Sleep) and later
powered up (wake-up from Sleep).
9.9.1 SLEEP
The Power-Down mode is entered by executing a
SLEEP instruction.
If enabled, the Watchdog Timer will be cleared but
keeps running, the TO bit (STATUS<4>) is set, the PD
bit (STATUS<3>) is cleared and the oscillator driver is
turned off. The I/O ports maintain the status they had
before the SLEEP instruction was executed (driving
high, driving low or high-impedance).
For lowest current consumption while powered down,
the T0CKI input should be at VDD or VSS and the GP3/
MCLR/VPP pin must be at a logic high level if MCLR is
enabled.
9.9.2 WAKE-UP FROM SLEEP
The device can wake-up from Sleep through one of
the following events:
1. An external Reset input on GP3/MCLR/VPP pin,
when configured as MCLR.
2. A Watchdog Timer time-out Reset (if WDT was
enabled).
3. A change on input pin GP0, GP1 or GP3 when
wake-up on change is enabled.
4. A comparator output change has occurred when
wake-up on comparator change is enabled.
These events cause a device Reset. The TO, PD
GPWUF and CWUF bits can be used to determine the
cause of device Reset. The TO bit is cleared if a WDT
time-out occurred (and caused wake-up). The PD bit,
which is set on power-up, is cleared when SLEEP is
invoked. The GPWUF bit indicates a change in state
while in Sleep at pins GP0, GP1 or GP3 (since the last
file or bit operation on GP port). The CWUF bit
indicates a change in the state while in Sleep of the

Note: A Reset generated by a WDT time-out
does not drive the MCLR pin low.
Note: This brown-out protection circuit employs
Microchip Technology’s MCP809 micro-
controller supervisor. There are 7 different

Note: Caution: Right before entering Sleep,
read the input pins. When in Sleep, wake-
up occurs when the values at the pins
change from the state they were in at the
last reading. If a wake-up on change
occurs and the pins are not read before re-
entering Sleep, a wake-up will occur
immediately even if no pins change while
in Sleep mode.
Note: The WDT is cleared when the device
wakes from Sleep, regardless of the wake-
up source.

9.10 Program Verification/Code
Protection
If the code protection bit has not been programmed, the
on-chip program memory can be read out for
verification purposes.
The first 64 locations and the last location (Reset
vector) can be read, regardless of the code protection
bit setting.
9.11 ID Locations
Four memory locations are designated as ID locations
where the user can store checksum or other code
identification numbers. These locations are not
accessible during normal execution, but are readable
and writable during Program/Verify.
Use only the lower 4 bits of the ID locations and always
program the upper 8 bits as ‘0’s.
9.12 In-Circuit Serial Programming™
The PIC10F200/202/204/206 microcontrollers can be
serially programmed while in the end application circuit.
This is simply done with two lines for clock and data,
and three other lines for power, ground and the
programming voltage. This allows customers to manu-
facture boards with unprogrammed devices and then
program the microcontroller just before shipping the
product. This also allows the most recent firmware or a
custom firmware, to be programmed.
The devices are placed into a Program/Verify mode by
holding the GP1 and GP0 pins low while raising the
MCLR (VPP) pin from VIL to VIHH (see programming
specification). GP1 becomes the programming clock
and GP0 becomes the programming data. Both GP1
and GP0 are Schmitt Trigger inputs in this mode.
After Reset, a 6-bit command is then supplied to the
device. Depending on the command, 16 bits of program
data are then supplied to or from the device, depending
if the command was a Load or a Read. For complete
details of serial programming, please refer to the
PIC10F200/202/204/206 Programming Specifications.
A typical In-Circuit Serial Programming connection is
shown in Figure 9-10.

10.0 INSTRUCTION SET SUMMARY
The PIC16 instruction set is highly orthogonal and is
comprised of three basic categories.
•Byte-oriented operations
•Bit-oriented operations
•Literal and control operations
Each PIC16 instruction is a 12-bit word divided into an
opcode, which specifies the instruction type and one or
more operands which further specify the operation of
the instruction. The formats for each of the categories
is presented in Figure 10-1, while the various opcode
fields are summarized in Table 10-1.
For byte-oriented instructions, ‘f’ represents a file
register designator and ‘d’ represents a destination
designator. The file register designator specifies which
file register is to be used by the instruction.
The destination designator specifies where the result of
the operation is to be placed. If ‘d’ is ‘0’, the result is
placed in the W register. If ‘d’ is ‘1’, the result is placed
in the file register specified in the instruction.
For bit-oriented instructions, ‘b’ represents a bit field
designator which selects the number of the bit affected
by the operation, while ‘f’ represents the number of the
file in which the bit is located.
For literal and control operations, ‘k’ represents an
8 or 9-bit constant or literal value.
TABLE 10-1: OPCODE FIELD
DESCRIPTIONS
All instructions are executed within a single instruction
cycle, unless a conditional test is true or the program
counter is changed as a result of an instruction. In this
case, the execution takes two instruction cycles. One
instruction cycle consists of four oscillator periods.
Thus, for an oscillator frequency of 4 MHz, the normal
instruction execution time is 1 s. If a conditional test is
true or the program counter is changed as a result of an
instruction, the instruction execution time is 2 s.
Figure 10-1 shows the three general formats that the
instructions can have. All examples in the figure use
the following format to represent a hexadecimal
number:
0xhhh
where ‘h’ signifies a hexadecimal digit.
FIGURE 10-1: GENERAL FORMAT FOR
INSTRUCTIONS
Field Description
f Register file address (0x00 to 0x7F)
W Working register (accumulator)
b Bit address within an 8-bit file register
k Literal field, constant data or label
x Don’t care location (= 0 or 1)
The assembler will generate code with x = 0. It is
the recommended form of use for compatibility with
all Microchip software tools.

Note 1: The 9th bit of the program counter will be forced to a ‘0’ by any instruction that writes to the PC except for
GOTO. See Section 4.7 “Program Counter”.
2: When an I/O register is modified as a function of itself (e.g. MOVF PORTB, 1), the value used will be that
value present on the pins themselves. For example, if the data latch is ‘1’ for a pin configured as input and
is driven low by an external device, the data will be written back with a ‘0’.
3: The instruction TRIS f, where f = 6, causes the contents of the W register to be written to the tri-state
latches of PORTB. A ‘1’ forces the pin to a high-impedance state and disables the output buffers.
4: If this instruction is executed on the TMR0 register (and where applicable, d = 1), the prescaler will be
cleared (if assigned to TMR0).

11.2 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
11.3 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
11.4 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
11.5 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

11.6 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.
