We welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000A is version A of document DS30000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision
of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
Microchip's Worldwide Web site; http://www.microchip.com
Your local Microchip sales office (see last page)
The Microchip Corporate Literature Center; U.S. FAX: (480) 792-7277
When contacting a sales office or the literature center, please specify which device, revision of silicon and data sheet (include liter-
ature number) you are using.

GENERAL DESCRIPTION
The PIC16C63A/65B/73B/74B devices are
low cost,
high performance, CMOS, fully-static, 8-bit micro-
controllers in the PIC16CXX mid-range family.
All PICmicro
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 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 reg-
ister set gives some of the architectural innovations
used to achieve a very high performance.
The PIC16C63A/73B devices have 22 I/O pins. The
PIC16C65B/74B devices have 33 I/O pins. Each
device has 192 bytes of RAM. In addition, several
peripheral features are available, including: three timer/
counters, two Capture/Compare/PWM modules, and
two serial ports. The Synchronous Serial Port (SSP)
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 Synchronous 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 on the
PIC16C73B, while the PIC16C74B offers 8 channels.
The 8-bit resolution is ideally suited for applications
requiring low cost analog interface, e.g., thermostat
control, pressure sensing, etc.
The PIC16C63A/65B/73B/74B devices have 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 oscillator minimizes power consumption, XT is
a standard crystal, and the HS is for high speed crys-
tals. 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 (WDT), with its own
on-chip RC oscillator, provides protection against soft-
ware lockup, and also provides one way of waking the
device from SLEEP.
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 PIC16C63A/65B/73B/74B devices fit nicely in
many applications ranging from security and remote
sensors to appliance control and automotive. The
EPROM technology makes customization of applica-
tion programs (transmitter codes, motor speeds,
receiver frequencies, etc.) extremely fast and con-
venient. The small footprint packages make this micro-
controller series perfect for all applications with space
limitations. Low cost, low power, high performance,
ease of use and I/O flexibility make the PIC16C63A/
65B/73B/74B devices 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
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
PICmicro
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.
