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 congured 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 congured 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 congured
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)
is
also
known
as
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 exibility
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.
