PIC16F5X

1.0

GENERAL DESCRIPTION

The PIC16F5X from Microchip Technology is a family

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

based CMOS microcontrollers. It 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

PIC16F5X 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 PIC16F5X 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

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 protec-

tion features improve system cost, power and reliability.

The PIC16F5X products are supported by a full-featured

macro assembler, a software simulator, a low-cost devel-

opment programmer and a full featured programmer. All

the tools are supported on IBM® PC and compatible

machines.

1.1

Applications

The PIC16F5X 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 Flash

technology makes customizing application programs

(transmitter

codes,

motor

speeds,

receiver

frequencies, etc.) extremely fast and convenient. 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 PIC16F5X series very versatile, even in

areas

where

microcontroller

use

has

been

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

of “glue” logic in larger systems, co-processor

applications).
