DEVICE OVERVIEW
This document contains device specific information for
the operation of the PIC16F72 device. Additional infor-
mation may be found in the PIC Mid-Range MCU
Reference Manual (DS33023), which may be down-
loaded from the Microchip website. The Reference
Manual should be considered a complementary docu-
ment to this data sheet, and is highly recommended
reading for a better understanding of the device archi-
tecture and operation of the peripheral modules.
The PIC16F72 belongs to the Mid-Range family of the
PIC devices. A block diagram of the device is shown in
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
instruction. The data memory (RAM) contains 128 bytes.
There are 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/I2C
Table 1-1 details the pinout of the device with
descriptions and details for each pin.
