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
family 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 reg-
ister 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
device has 192 bytes of RAM and 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 (I
2
C) bus. The Universal Syn-
chronous
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
devices have 192 bytes of RAM
and 33 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 (I
2
C) bus. The Universal Syn-
chronous
Asynchronous
Receiver
Transmitter
(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 crys-
tals. 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
reset(s).
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
microcontroller use has been considered before (e.g.
timer functions, serial communication, capture and
compare, PWM functions, and co-processor applica-
tions).
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
The PIC16CXX family is supported by a full-featured
macro assembler, a software simulator, an in-circuit
emulator, a low-cost development programmer, and a
full-featured programmer. A “C” compiler and fuzzy
logic support tools are also available.
