PIC16C745/765

GENERAL DESCRIPTION
The PIC16C745/765 devices are low cost, high-perfor-
mance, CMOS, fully-static, 8-bit microcontrollers in the
PIC16CXX mid-range family.
All PICmicro microcontrollers employ an advanced
RISC architecture. The PIC16C745/765 microcontrol-
ler 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 PIC16C745
device has 22 I/O
pins. The
PIC16C765 device has 33 I/O pins. Each device has
256 bytes of RAM. In addition, several peripheral fea-
tures are available including: three timer/counters, two
Capture/Compare/PWM modules and two serial ports.
The Universal Serial Bus (USB 1.1) low speed periph-
eral provides bus communications. 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 PIC16C745, while the
PIC16C765 offers 8 channels. The 8-bit resolution is
ideally suited for applications requiring a low cost ana-
log interface (e.g., thermostat control, pressure sens-
ing, etc.).
The PIC16C745/765 devices have special features to
reduce external components, thus reducing cost,
enhancing system reliability and reducing power con-
sumption. There are 4 oscillator options, of which EC is
for the external regulated clock source, E4 is for the
external regulated clock source with the PLL enabled,
HS is for the high speed crystals/resonators and H4 is
for high speed crystals/resonators with the PLL
enabled. 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 a dedi-
cated on-chip RC oscillator, provides protection against
software lock-up, 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 PIC16C745/765 devices fit nicely in many applica-
tions ranging from security and remote sensors to appli-
ance
controls
and
automotives.
The
EPROM
technology makes customization of application pro-
grams
(data
loggers,
industrial
controls,
UPS)
extremely fast and convenient. The small footprint pack-
ages make this microcontroller series perfect for all
applications with space limitations. Low-cost, low-
power, high-performance, ease of use and I/O flexibility
make the PIC16C745/765 devices very versatile, even
in areas where no microcontroller use has been consid-
ered 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.
Code
written
for
the
PIC16C5X can be easily ported to the PIC16C745/765
family of devices.
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.
