PIC16C7X

1.0

GENERAL DESCRIPTION

The PIC16C7X 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 PIC16C72 has 128 bytes of RAM and 22 I/O pins.

In addition several peripheral features are available

including: three timer/counters, one Capture/Compare/

PWM module and one serial port. The Synchronous

Serial Port can be conﬁgured as either a 3-wire Serial

Peripheral Interface (SPI) or the two-wire Inter-Inte-

grated Circuit (I2C) bus. Also a 5-channel high-speed

8-bit A/D is provided. The 8-bit resolution is ideally

suited for applications requiring low-cost analog inter-

face, e.g. thermostat control, pressure sensing, etc.

The PIC16C73/73A devices have 192 bytes of RAM,

while the PIC16C76 has 368 byes of RAM. Each device

has 22 I/O pins. In addition, several peripheral features

are available including: three timer/counters, two Cap-

ture/Compare/PWM modules and two serial ports. The

Synchronous Serial Port can be conﬁgured as either a

3-wire Serial Peripheral Interface (SPI) or the two-wire

Inter-Integrated Circuit (I2C) bus. The Universal Syn-

chronous

Asynchronous

Receiver

Transmitter

(USART) is also known as the Serial Communications

Interface or SCI. Also a 5-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 PIC16C74/74A devices have 192 bytes of RAM,

while the PIC16C77 has 368 bytes of RAM. Each

device has 33 I/O pins. In addition several peripheral

features are available including: three timer/counters,

two Capture/Compare/PWM modules and two serial

ports. The Synchronous Serial Port can be conﬁgured

as either a 3-wire Serial Peripheral Interface (SPI) or

the two-wire Inter-Integrated Circuit (I2C) bus. The Uni-

versal Synchronous Asynchronous Receiver Transmit-

ter

(USART)

also

known

the

Serial

Communications Interface or SCI. An 8-bit Parallel

Slave Port is provided. Also an 8-channel high-speed

8-bit A/D is provided. The 8-bit resolution is ideally

suited for applications requiring low-cost analog inter-

face, e.g. thermostat control, pressure sensing, etc.

The PIC16C7X 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 PIC16C7X family fits perfectly in applications rang-

ing from security and remote sensors to appliance con-

trol and automotive. The EPROM technology makes

customization of application programs (transmitter

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 PIC16C7X very versatile even in areas where

no microcontroller use has been considered before

(e.g. timer functions, serial communication, capture

and compare, PWM functions and coprocessor appli-

cations).

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

PIC16C7X devices are supported by the complete line

of Microchip Development tools.

Please refer to Section 16.0 for more details about

Microchip’s development tools.
