GENERAL DESCRIPTION

The PIC16C5X from Microchip Technology is a family

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

EPROM/ROM-based

CMOS

microcontrollers.

employs a RISC architecture with only 33 single word/

single cycle instructions. All instructions are single

cycle except for program branches which take two

cycles. The PIC16C5X delivers performance in 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 PIC16C5X products are equipped with special fea-

tures 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 the power saving LP (Low Power) oscillator

and cost saving RC oscillator. Power saving SLEEP

mode, Watchdog Timer and Code Protection features

improve system cost, power and reliability.

The UV erasable CERDIP packaged versions are ideal

for code development, while the cost effective One

Time Programmable (OTP) versions 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 PIC16C5X products are supported by a full fea-

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

cuit emulator, a low cost development programmer and

a full featured programmer. All the tools are supported

on IBM® PC and compatible machines.

1.1

Applications

The PIC16C5X series fits perfectly in applications rang-

ing from high speed automotive and appliance motor

control to low power remote transmitters/receivers,

pointing devices and telecom processors. The EPROM

technology makes customizing application programs

(transmitter codes, motor speeds, receiver frequen-

cies, etc.) extremely fast and convenient. The small

footprint packages, for through hole or surface mount-

ing, make this microcontroller series perfect for applica-

tions with space limitations. Low cost, low power, high

performance ease of use and I/O flexibility make the

PIC16C5X series very versatile even in areas where no

microcontroller use has been considered before (e.g.,

timer functions, replacement of “glue” logic in larger

systems, co-processor applications).
