This document contains device-specific information for
the operation of the PIC16C72 device. Additional information
may be found in the PICmicro? Mid-Range
MCU Reference 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
PICmicro devices. A block diagram of the device is
shown in Figure 1-1.

The program memory contains 2K words which translate
to 2048 instructions, since each 14-bit program
memory word is the same width as each device instruction.
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

Table 1-1 details the pinout of the device with descriptions
and details for each pin.
