8-Pin, 8-Bit CMOS Microcontroller with EEPROM Data Memory

Microchip Technology 

1.0 GENERAL DESCRIPTION

The 8-pin PIC12CE5XX from Microchip Technology is

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

EPROM/EEPROM-based CMOS microcontrollers. It

employs 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 PIC12CE5XX 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 PIC12CE5XX products are equipped with special

features that reduce system cost and power require-

ments. The Power-On Reset (POR) and Device Reset

Timer (DRT) eliminate the need for external reset cir-

cuitry. There are four oscillator configurations to choose

from, including INTRC internal oscillator mode and the

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

SLEEP mode, Watchdog Timer and code protection

features improve system cost, power and reliability.

The PIC12CE5XX 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 PIC12CE5XX products are supported by a full-fea-

tured macro assembler, a software simulator, an in-cir-

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

a low-cost development programmer, and a full fea-

tured programmer. All the tools are supported on IBM®

PC and compatible machines.

1.1 Applications

The PIC12CE5XX series fits perfectly in applications

ranging from sensory systems, gas detectors and

security systems to low-power remote transmitters/

receivers. The EPROM programming 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 cal-

ibrations factors and security codes, the small footprint

8-pin packages, for through hole or surface mounting,

make this microcontroller series perfect for applications

with space limitations. Low-cost, low-power, high per-

formance, ease of use and I/O flexibility make the

PIC12CE5XX 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).
