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
2
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
2
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
2
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
2
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 customi-
zation 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.
