Applications  
1.0  
GENERAL DESCRIPTION  
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).  
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 µs) 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  
external 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.

sequential.  
A variety of packaging options are available. Depend-  
ing on application and production requirements, the  
proper device option can be selected using the  
information in this section. When placing orders, please  
use the PIC10F200/202/204/206 Product Identification  
System at the back of this data sheet to specify the  
correct part number.  
Serial programming allows each device to have a

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.

PIC10F200/202/204/206  
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.  
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 µs @ 4 MHz) except for program branches.  
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  
constant. 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.  
The table below lists program memory (Flash) and data  
memory (RAM) for the PIC10F200/202/204/206  
devices.  
A simplified block diagram is shown in Figure 3-1 and  
Figure 3-2, with the corresponding device pins  
described in Table 3-2.

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.

Clocking Scheme/Instruction  
Cycle  
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).  
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.  
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).

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 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  
PIC10F202/206 are physically implemented (see  
Figure 4-2). Accessing  
boundaries will cause a wraparound within the first  
512 x 12 space (PIC10F202/206). The effective  
Reset vector is at 0000h (see Figure 4-2). Location  
01FFh (PIC10F202/206) contains the internal clock  
oscillator calibration value. This value should never  
be overwritten.  
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.  
a location above these  
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).  
FIGURE 4-2:

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.

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).  
4.4  
Status Register  
This register contains the arithmetic status of the ALU,  
the Reset status and the page preselect bit.  
Therefore, it is recommended that only BCF, BSFand  
MOVWFinstructions be used to alter the Status register.  
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”.  
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.

EFFECTS OF RESET  
4.7  
Program Counter  
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.  
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 GOTOinstruction, bits 8:0 of the PC are provided  
by the GOTO instruction word. The Program Counter  
(PCL) is mapped to PC<7:0>.  
4.8  
Stack  
The PIC10F200/204 devices have a 2-deep, 8-bit wide  
hardware PUSH/POP stack.  
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).  
The PIC10F202/206 devices have a 2-deep, 9-bit wide  
hardware PUSH/POP stack.  
A CALLinstruction 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.  
Instructions where the PCL is the destination, or modify  
PCL instructions, include MOVWF PC, ADDWF PCand  
BSF PC,5.  
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).  
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 that  
the W register will be loaded with the literal value  
specified in the instruction. This is particularly useful for  
the implementation of data look-up tables within the  
program memory.

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.  
• Increment the value of the FSR register by one  
(FSR = 0A)  
• A read of the INDR register now will return the  
value of 0Ah.  
The FSR<4:0> bits are used to select data memory  
addresses 00h to 1Fh.  
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).  
Note:  
PIC10F200/202/204/206 – Do not use  
banking. FSR <7:5> are unimplemented  
and read as ‘1’s.

I/O Interfacing  
5.0  
I/O PORT  
The equivalent circuit for an I/O port pin is shown in  
Figure 5-2. 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.  
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.

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.

INSTRUCTIONS ON AN  
I/O PORT  
5.4  
I/O Programming Considerations  
5.4.1  
BIDIRECTIONAL I/O PORTS  
Some instructions operate internally as read followed  
by write operations. The BCFand BSFinstructions, 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 BSFoperation 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.

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 NOPor another instruction not  
accessing this I/O port.  
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.

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. Restrictions on the  
external clock input are discussed in detail in  
Section 6.1 “Using Timer0 with an External Clock  
(PIC10F200/202)”.

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  
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.  
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.  
A summary of registers associated with the Timer0  
module is found in Table 6-1.

EXTERNAL CLOCK  
SYNCHRONIZATION  
6.1  
Using Timer0 with an External  
Clock (PIC10F200/202)  
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 TOSC (and a small RC delay of 2 Tt0H) and low  
for at least 2 TOSC (and a small RC delay of 2 Tt0H).  
Refer to the electrical specification of the desired  
device.  
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.  
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.

6.2.1  
SWITCHING PRESCALER  
ASSIGNMENT  
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 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.  
Note:  
The prescaler may be used by either the  
Timer0 module or the WDT, but not both.  
Thus, a prescaler assignment for the  
Timer0 module means that there is no  
prescaler for the WDT and vice versa.

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.

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:

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 comparator 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. Clearing 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)”  
- 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.  
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.  
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)”.

(and a small RC delay of 2 Tt0H). Refer to the electrical  
specification of the desired device.  
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.  
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.  
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

7.1.2  
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 7-4 shows the  
delay from the external clock edge to the timer  
incrementing.

SWITCHING PRESCALER  
ASSIGNMENT  
7.2  
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 Figure 9-6). For  
simplicity, this counter is being referred to as  
“prescaler” throughout this data sheet.  
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 7-1) must  
be executed when changing the prescaler assignment  
from Timer0 to the WDT.  
Note:  
The prescaler may be used by either the  
Timer0 module or the WDT, but not both.  
Thus, a prescaler assignment for the  
Timer0 module means that there is no  
prescaler for the WDT and vice versa.

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.

To change the prescaler from the WDT to the Timer0  
module, use the sequence shown in Example 7.2. This  
sequence must be used even if the WDT is disabled. A  
CLRWDT instruction should be executed before  
switching the prescaler.

The Comparator module contains one analog  
comparator. The inputs to the comparator are  
multiplexed with GP0 and GP1 pins. The output of the  
comparator can be placed on GP2.  
The CMCON0 register, shown in Register 8-1, controls  
the comparator operation. A block diagram of the

Comparator Operation  
8.5  
Comparator Output  
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.  
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.  
Note:  
Analog levels on any pin that is defined as  
a digital input may cause the input buffer to  
consume more current than is specified.  
8.6  
Comparator Wake-up Flag  
The comparator wake-up flag is set whenever all of the  
following conditions are met:

Comparator Operation During  
Sleep  
VIN+  
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.  
Result  
8.3  
Comparator Reference  
8.8  
Effects of a Reset  
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.  
A POR Reset 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.  
8.4  
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.  
8.9  
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 kΩ  
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.

PIC10F200/202/204/206  
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.

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:  
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.

• 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  
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.  
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.  
OSCCAL, when written to with the calibration value, will  
“trim” the internal oscillator to remove process variation  
from the oscillator frequency.  
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.

A simplified block diagram of the on-chip Power-on  
Reset circuit is shown in Figure 9-2.  
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.  
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.  
FIGURE 9-1:  
MCLR SELECT  
GPWU  
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.  
GP3/MCLR/VPP  
Internal MCLR  
MCLRE  
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).  
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 12-3 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.  
Note:  
When the devices start normal operation  
(exit the Reset condition), device operat-  
ing parameters (voltage, frequency,  
temperature, etc.) must be met to ensure  
operation. If these conditions are not met,  
the device must be held in Reset until the  
operating conditions are met.  
For additional information, refer to Application Notes  
AN522 “Power-Up Considerations”, (DS00522) and  
AN607 “Power-up Trouble Shooting”, (DS00607).  
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.

PIC10F200/202/204/206  
9.6.1  
WDT PERIOD  
9.5  
Device Reset Timer (DRT)  
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 periods  
vary with temperature, VDD and part-to-part process  
variations (see DC specs).  
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.  
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 Device Reset Time delays will vary from chip-to-  
chip due to VDD, temperature and process variation.  
See AC parameters for details.  
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.  
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.

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.

The device can wake-up from Sleep through one of  
the following events:

when configured as MCLR.  
MCP809  
VDD

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.  
PIC10F20X  
4. A comparator output change has occurred when  
wake-up on comparator change is enabled.  
Note:  
This Brown-out Protection circuit employs  
Microchip Technology’s MCP809 micro-  
controller supervisor. There are 7 different  
trip point selections to accommodate 5V to  
3V systems.  
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  
comparator output.  
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  
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.  
The Power-down mode is entered by executing a  
SLEEPinstruction.  
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).  
Note:  
A Reset generated by a WDT time-out  
does not drive the MCLR pin low.  
Note:  
The WDT is cleared when the device  
wakes from Sleep, regardless of the wake-  
up source.  
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.

9.12 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.

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 µs. If a conditional test is  
true or the program counter is changed as a result of an  
instruction, the instruction execution time is 2 µs.  
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.  
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  
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.  
where ‘h’ signifies a hexadecimal digit.  
FIGURE 10-1:  
GENERAL FORMAT FOR  
INSTRUCTIONS  
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.

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).

11.6 MPLAB ASM30 Assembler, Linker  
and Librarian  
The MPLAB C17 and MPLAB C18 Code Development  
MPLAB ASM30 assembler produces relocatable  
machine code from symbolic assembly language for  
dsPIC30F devices. MPLAB C30 compiler uses the  
assembler to produce it’s 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:  
Systems are complete ANSI  
C
compilers for  
Microchip’s PIC17CXXX and PIC18CXXX family of  
microcontrollers. These compilers provide powerful  
integration capabilities, superior code optimization and  
ease of use not found with other compilers.  
For easy source level debugging, the compilers provide  
symbol information that is optimized to the MPLAB IDE  
debugger.  
• Support for the entire dsPIC30F instruction set  
• Support for fixed-point and floating-point data  
• Command line interface  
11.4 MPLINK Object Linker/  
MPLIB Object Librarian  
• Rich directive set  
The MPLINK object linker combines relocatable  
objects created by the MPASM assembler and the  
MPLAB C17 and MPLAB C18 C compilers. It can link  
relocatable objects from precompiled libraries, using  
directives from a linker script.  
• Flexible macro language  
• MPLAB IDE compatibility  
11.7 MPLAB SIM Software Simulator  
The MPLAB SIM software simulator allows code devel-  
opment in a PC hosted environment by simulating the  
PICmicro series microcontrollers on an instruction  
level. On any given instruction, the data areas can be  
examined or modified and stimuli can be applied from  
a file, or user defined key press, to any pin. The execu-  
tion can be performed in Single-Step, Execute Until  
Break or Trace mode.  
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  
The MPLAB SIM simulator fully supports symbolic  
debugging using the MPLAB C17 and MPLAB C18  
C Compilers, as well as the MPASM assembler. The  
software simulator offers the flexibility to develop and  
debug code outside of the laboratory environment,  
making it an excellent, economical software  
development tool.  
• Enhanced code maintainability by grouping  
related modules together  
• Flexible creation of libraries with easy module  
listing, replacement, deletion and extraction  
11.5 MPLAB C30 C Compiler  
11.8 MPLAB SIM30 Software Simulator  
The MPLAB C30 C compiler is a full-featured, ANSI  
compliant, optimizing compiler that translates standard  
ANSI C programs into dsPIC30F assembly language  
source. The compiler also supports many command  
line options and language extensions to take full  
advantage of the dsPIC30F device hardware capabili-  
ties and afford fine control of the compiler code  
generator.  
The MPLAB SIM30 software simulator allows code  
development in a PC hosted environment by simulating  
the dsPIC30F series microcontrollers on an instruction  
level. On any given instruction, the data areas can be  
examined or modified and stimuli can be applied from  
a file, or user defined key press, to any of the pins.  
The MPLAB SIM30 simulator fully supports symbolic  
debugging using the MPLAB C30 C Compiler and  
MPLAB ASM30 assembler. The simulator runs in either  
a Command Line mode for automated tasks, or from  
MPLAB IDE. This high-speed simulator is designed to  
debug, analyze and optimize time intensive DSP  
routines.  
MPLAB C30 is distributed with a complete ANSI C  
standard library. All library functions have been vali-  
dated and conform to the ANSI C library standard. The  
library includes functions for string manipulation,  
dynamic memory allocation, data conversion, time-  
keeping and math functions (trigonometric, exponential  
and hyperbolic). The compiler provides symbolic  
information for high-level source debugging with the  
MPLAB IDE.

11.11 MPLAB ICD 2 In-Circuit Debugger  
Microchip’s In-Circuit Debugger, MPLAB ICD 2, is a  
powerful, low-cost, run-time development tool,  
connecting to the host PC via an RS-232 or high-speed  
USB interface. This tool is based on the Flash  
PICmicro MCUs and can be used to develop for these  
and other PICmicro microcontrollers. The MPLAB  
ICD 2 utilizes the in-circuit debugging capability built  
into the Flash devices. This feature, along with  
In-Circuit Emulator  
The MPLAB ICE 2000 universal in-circuit emulator is  
intended to provide the product development engineer  
with a complete microcontroller design tool set for  
PICmicro microcontrollers. Software control of the  
MPLAB ICE 2000 in-circuit emulator is advanced by  
the MPLAB Integrated Development Environment,  
which allows editing, building, downloading and source  
debugging from a single environment.  
Microchip’s In-Circuit Serial ProgrammingTM (ICSPTM  
)
protocol, offers cost effective in-circuit Flash debugging  
from the graphical user interface of the MPLAB  
Integrated Development Environment. This enables a  
designer to develop and debug source code by setting  
breakpoints, single-stepping and watching variables,  
CPU status and peripheral registers. Running at full  
speed enables testing hardware and applications in  
real-time. MPLAB ICD 2 also serves as a development  
programmer for selected PICmicro devices.  
The MPLAB ICE 2000 is a full-featured emulator sys-  
tem with enhanced trace, trigger and data monitoring  
features. Interchangeable processor modules allow the

These parameters are characterized but not tested.  
Data in the Typical (“Typ”) column is at 5V, 25°C unless otherwise stated. These parameters are for design  
guidance only and are not tested.  
Note 1: To ensure these oscillator frequency tolerances, VDD and VSS must be capacitively decoupled as close to  
the device as possible. 0.1 µF and 0.01 µF values in parallel are recommended.
