1.0
PIC16C64X & PIC16C66X devices are 28-pin and
40-pin EPROM-based members of the versatile
PIC16CXXX family of low-cost, high-performance,
CMOS, fully-static, 8-bit microcontrollers.
All PIC16/17 microcontrollers employ an advanced
RISC architecture. The PIC16CXXX 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 sin-
gle-cycle, except for program branches (which require
two cycles). A total of 35 instructions (reduced instruc-
tion set) are available. Additionally, a large register set
gives some of the architectural innovations used to
achieve a very high performance.
PIC16CXXX microcontrollers typically achieve a 2:1
code compression and a 4:1 speed improvement over
other 8-bit microcontrollers in its class.
The PIC16C641 has 128 bytes of RAM and the
PIC16C642 has 176 bytes of RAM. Both devices have
22 I/O pins, and an 8-bit timer/counter with an 8-bit pro-
grammable prescaler. In addition, they have two analog
comparators with a programmable on-chip voltage ref-
erence module. Program Memory has internal parity
error detection circuitry with a Parity Error Reset. The
comparator module is ideally suited for applications
requiring a low-cost analog interface (e.g., battery
chargers,
controllers, etc.).
The PIC16C661 has 128 bytes of RAM and the
PIC16C662 has 176 bytes of RAM. Both devices have
33 I/O pins, and an 8-bit timer/counter with an 8-bit pro-
grammable prescaler. They also have an 8-bit Parallel
Slave Port. In addition, the devices have two analog
comparators with a programmable on-chip voltage ref-
erence module. Program Memory has internal parity
error detection circuitry with a Parity Error Reset. The
comparator module is ideally suited for applications
requiring a low-cost analog interface (e.g., battery
chargers,
controllers, etc.).
PIC16CXXX 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 crystals.
The SLEEP (power-down) mode offers power saving.
The user can wake-up the chip from SLEEP through
several external and internal interrupts and resets.

Preliminary
PIC16C64X & PIC16C66X
A highly reliable Watchdog Timer (WDT) with its own
on-chip RC oscillator provides protection against soft-
ware 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 PIC16CXXX series fit perfectly in applications
ranging from battery chargers to low-power remote
sensors.
customization of application programs (detection
levels, pulse generation, timers, etc.) extremely fast
and convenient. The small footprint packages make
this microcontroller series perfect for all applications
with
high-performance, ease of use, and I/O flexibility make
the PIC16C64X & PIC16C66X very versatile.
