DEVICE OVERVIEW
This document contains device-specific information for
the operation of the PIC16C72 device. Additional infor-
mation may be found in the PIC
®
Mid-Range MCU Ref-
erence Manual (DS33023) which may be downloaded
from the Microchip website. The Reference Manual
should be considered a complementary document to
this data sheet, and is highly recommended reading for
a better understanding of the device architecture and
operation of the peripheral modules.
The PIC16C72 belongs to the Mid-Range family of the
PIC devices. A block diagram of the device is shown in
Figure 1-1.
The program memory contains 2K words which trans-
late to 2048 instructions, since each 14-bit program
memory word is the same width as each device instruc-
tion. The data memory (RAM) contains 128 bytes.
There are also 22 I/O pins that are user-configurable on
a pin-to-pin basis. Some pins are multiplexed with other
device functions. These functions include:
•
•
•
•
•
•
•
External interrupt
Change on PORTB interrupt
Timer0 clock input
Timer1 clock/oscillator
Capture/Compare/PWM
A/D converter
SPI/I
