1.0 GENERAL DESCRIPTION

The PIC12C5XX from Microchip Technology is a family

of low-cost, high performance, 8-bit, fully static,

EEPROM/EPROM/ROM-based CMOS microcontrollers.

It employs a RISC architecture with only 33 single

word/single cycle instructions. All instructions are

single cycle (1 ms) except for program branches

which take two cycles. The PIC12C5XX delivers performance

an order of magnitude higher than its competitors

in the same price category. The 12-bit wide

instructions are highly symmetrical resulting in 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 PIC12C5XX 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.

There are four oscillator configurations to choose

from, including INTRC internal oscillator mode and the

power-saving LP (Low Power) oscillator mode. Power

saving SLEEP mode, Watchdog Timer and code

protection features also improve system cost, power

and reliability.

The PIC12C5XX are available in the cost-effective

One-Time-Programmable (OTP) versions which are

suitable for production in any volume. The customer

can take full advantage of Microchip’s price leadership

in OTP microcontrollers while benefiting from the OTP’s

flexibility.

The PIC12C5XX products are supported by a full-featured

macro assembler, a software simulator, an in-circuit

emulator, a ‘C’ compiler, fuzzy logic support tools,

a low-cost development programmer, and a full featured

programmer. All the tools are supported on IBMò

PC and compatible machines.

1.1 Applications

The PIC12C5XX series fits perfectly in applications

ranging from personal care appliances and security

systems to low-power remote transmitters/receivers.

The EPROM technology makes customizing application

programs (transmitter codes, appliance settings,

receiver frequencies, etc.) extremely fast and convenient,

while the EEPROM data memory technology

allows for the changing of calibration factors and security

codes. The small footprint packages, for through

hole or surface mounting, make this microcontroller

series perfect for applications with space limitations.

Low-cost, low-power, high performance, ease of use

and I/O flexibility make the PIC12C5XX series very versatile

even in areas where no microcontroller use has

been considered before (e.g., timer functions, replacement

of “glue” logic and PLD’s in larger systems, coprocessor

applications).
