This document contains device-specific information for
the operation of the PIC16C72 device. Additional infor-
mation may be found in the PICmicro™ Mid-Range
MCU Reference Manual (DS33023) which may be
downloaded from the Microchip website. The Refer-
ence Manual should be considered a complementary
document to this data sheet, and is highly recom-
mended 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 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
Table 1-1 details the pinout of the device with descrip-
tions and details for each pin.
