PIC16C71X

1.0

GENERAL DESCRIPTION

The PIC16C71X is a family of low-cost, high-perfor-

mance, CMOS, fully-static, 8-bit microcontrollers with

integrated analog-to-digital (A/D) converters, in the

PIC16CXX mid-range family.

All PIC16/17 microcontrollers employ an advanced

RISC architecture. The PIC16CXX microcontroller fam-

ily has enhanced core features, eight-level deep stack,

and multiple internal and external interrupt sources.

The separate instruction and data buses of the Harvard

architecture allow a 14-bit wide instruction word with

the separate 8-bit wide data. The two stage instruction

pipeline allows all instructions to execute in a single

cycle, except for program branches which require two

cycles. A total of 35 instructions (reduced instruction

set) are available. Additionally, a large register set gives

some of the architectural innovations used to achieve a

very high performance.

PIC16CXX microcontrollers typically achieve a 2:1

code compression and a 4:1 speed improvement over

other 8-bit microcontrollers in their class.

The PIC16C710/71 devices have 36 bytes of RAM, the

PIC16C711 has 68 bytes of RAM and the PIC16C715

has 128 bytes of RAM. Each device has 13 I/O pins. In

addition a timer/counter is available. Also a 4-channel

high-speed 8-bit A/D is provided. The 8-bit resolution is

ideally suited for applications requiring low-cost analog

interface, e.g. thermostat control, pressure sensing,

etc.

The PIC16C71X family has special features to reduce

external components, thus reducing cost, enhancing

system reliability and reducing power consumption.

There are four oscillator options, of which the single pin

RC oscillator provides a low-cost solution, the LP oscil-

lator minimizes power consumption, XT is a standard

crystal, and the HS is for High Speed crystals. The

SLEEP (power-down) feature provides a power saving

mode. The user can wake up the chip from SLEEP

through several external and internal interrupts and

resets.

A highly reliable Watchdog Timer with its own on-chip

RC oscillator provides protection against software lock-

up.

A UV erasable CERDIP packaged version is ideal for

code development while the cost-effective One-Time-

Programmable (OTP) version is suitable for production

in any volume.

The PIC16C71X family ﬁts perfectly in applications

ranging from security and remote sensors to appliance

control and automotive. The EPROM technology

makes customization of application programs (trans-

mitter codes, motor speeds, receiver frequencies, etc.)

extremely fast and convenient. The small footprint

packages make this microcontroller series perfect for

all applications with space limitations. Low cost, low

power, high performance, ease of use and I/O ﬂexibility

make the PIC16C71X very versatile even in areas

where no microcontroller use has been considered

before (e.g. timer functions, serial communication, cap-

ture and compare, PWM functions and coprocessor

applications).

1.1

Family and Upward Compatibility

Users familiar with the PIC16C5X microcontroller fam-

ily will realize that this is an enhanced version of the

PIC16C5X architecture. Please refer to Appendix A for

a detailed list of enhancements. Code written for the

PIC16C5X can be easily ported to the PIC16CXX fam-

ily of devices (Appendix B).

1.2

Development Support

PIC16C71X devices are supported by the complete

line of Microchip Development tools.

Please refer to Section 10.0 for more details about

Microchip’s development tools.
