This data sheet covers the PIC17C7XX group of the
PIC17CXXX family of microcontrollers. The following
devices are discussed in this data sheet:
• PIC17C752
• PIC17C756A
• PIC17C762
• PIC17C766
The PIC17C7XX devices are 68/84-pin, EPROM
based members of the versatile PIC17CXXX family of
low cost, high performance, CMOS, fully static, 8-bit
microcontrollers.
All PICmicro
RISC architecture. The PIC17CXXX has enhanced
core features, 16-level deep stack, and multiple internal
and external interrupt sources. The separate instruc-
tion and data buses of the Harvard architecture allow a
16-bit wide instruction word with a separate 8-bit wide
data path. The two stage instruction pipeline allows all
instructions to execute in a single cycle, except for pro-
gram branches (which require two cycles). A total of 58
instructions (reduced instruction set) are available.
Additionally, a large register set gives some of the
architectural innovations used to achieve a very high
performance. For mathematical intensive applications,
all devices have a single cycle 8 x 8 Hardware
Multiplier.
PIC17CXXX microcontrollers typically achieve a 2:1
code compression and a 4:1 speed improvement over
other 8-bit microcontrollers in their class.
PIC17C7XX devices have up to 902 bytes of RAM and
66
peripheral features, useful in many high performance
applications, including:
• Four timer/counters
• Four capture inputs
• Three PWM outputs
• Two independent Universal Synchronous Asyn-
• An A/D converter (multi-channel, 10-bit resolution)
• A Synchronous Serial Port
These special features 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 LF oscil-
lator is for low frequency crystals and minimizes power
consumption, XT is a standard crystal and the EC is for
external clock input.
The SLEEP (power-down) mode offers additional
power saving. Wake-up from SLEEP can occur through
several external and internal interrupts and device

A highly reliable Watchdog Timer with its own on-chip
RC oscillator provides protection against software mal-
function.
There are four configuration options for the device
operational mode:
• Microprocessor
• Microcontroller
• Extended microcontroller
• Protected microcontroller
The microprocessor and extended microcontroller
modes allow up to 64K-words of external program
memory.
The device also has Brown-out Reset circuitry. This
allows a device RESET to occur if the device V
below the Brown-out voltage trip point (BV
will remain in Brown-out Reset until V

A UV erasable, CERQUAD packaged version (compat-
ible with PLCC), is ideal for code development, while
the cost-effective One-Time-Programmable (OTP) ver-
sion is suitable for production in any volume.
The PIC17C7XX fits perfectly in applications that
require extremely fast execution of complex software
programs. These include applications ranging from
precise motor control and industrial process control to
automotive, instrumentation, and telecom applications.
The EPROM technology makes customization of appli-
cation programs (with unique security codes, combina-
tions, model numbers, parameter storage, etc.) fast
and convenient. Small footprint package options
(including die sales) make the PIC17C7XX ideal for
applications with space limitations that require high
performance.
High speed execution, powerful peripheral features,
flexible I/O, and low power consumption all at low cost
make the PIC17C7XX ideal for a wide range of embed-
ded control applications.
1.1
The PIC17CXXX family of microcontrollers have archi-
tectural enhancements over the PIC16C5X and
PIC16CXX families. These enhancements allow the
device to be more efficient in software and hardware
requirements. Refer to Appendix A for a detailed list of
enhancements and modifications. Code written for
PIC16C5X or PIC16CXX can be easily ported to
PIC17CXXX devices (Appendix B).
1.2
The PIC17CXXX family is supported by a full featured
macro assembler, a software simulator, an in-circuit
emulator, a universal programmer, a “C” compiler and
fuzzy logic support tools. For additional information,
see Section 19.0.
