DEVICE OVERVIEW

This document contains device specific information for the operation of the PIC16F72 device. Additional information 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 document to this data sheet, and is highly recommended reading for a better understanding of the device architecture and operation of the peripheral modules.
