1.0 DEVICE OVERVIEW

This document contains device specific information

about the PIC16F872 microcontroller. Additional infor-

mation may be found in the PICmicro™ Mid-Range

Reference Manual (DS33023), which may be obtained

from your local Microchip Sales Representative or

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 block diagram of the PIC16F872 architecture is

shown in Figure 1-1. A pinout description is provided in

Table 1-2.
