GENERAL DESCRIPTION

The PIC16CXX is a family of low-cost, high-perfor-

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

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

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

PIC16C61

device has 36 bytes of RAM and 13 I/O

pins. In addition a timer/counter is available.

The

PIC16C62/62A/R62

devices have 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-Integrated Circuit (I

C) bus.

The

PIC16C63/R63

devices have 192 bytes of RAM,

while the

PIC16C66

has 368 bytes. All three devices

have 22 I/O pins. In addition, several peripheral fea-

tures 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 (I

C) bus. The Univer-

sal Synchronous Asynchronous Receiver Transmitter

(USART) is also know as a Serial Communications

Interface or SCI.

The

PIC16C64/64A/R64

devices have 128 bytes of

RAM and 33 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-Integrated Circuit (I

C) bus. An 8-bit

Parallel Slave Port is also provided.

The

PIC16C65/65A/R65

devices have 192 bytes of

RAM, while the

PIC16C67

has 368 bytes. All four

devices have 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 (I

C) bus. The Uni-

versal Synchronous Asynchronous Receiver Transmit-

ter (USART) is also known as a Serial Communications

Interface or SCI. An 8-bit Parallel Slave Port is also pro-

vided.

The PIC16C6X device family has special features to

reduce external components, thus reducing cost,

enhancing system reliability and reducing power con-

sumption. There are four oscillator options, of which the

single pin RC oscillator provides a low-cost solution,

the LP oscillator minimizes power consumption, XT is a

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

The SLEEP (power-down) mode offers a power saving

mode. The user can wake 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 PIC16C6X family fits perfectly in applications rang-

ing from high-speed automotive and appliance control

to low-power remote sensors, keyboards and telecom

processors. The EPROM technology makes custom-

ization 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 applica-

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

performance, ease-of-use, and I/O flexibility make the

PIC16C6X very versatile even in areas where no micro-

controller use has been considered before (e.g. timer

functions, serial communication, capture and compare,

PWM functions, and co-processor applications).

1.1

Family and Upward Compatibility

Those users familiar with the PIC16C5X family of

microcontrollers 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 PIC16C5X can be easily ported to

PIC16CXX family of devices (Appendix B).

1.2

Development Support

PIC16C6X devices are supported by the complete line

of Microchip Development tools.

Please refer to Section 15.0 for more details about

Microchip’s development tools.
