DEVICE OVERVIEW

This document contains device-specific information.

Additional information may be found in the PICmicroTM

Mid-Range

MCU

Family

Reference

Manual,

(DS33023), which may be obtained from your local

Microchip Sales Representative or 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.

There are three devices (PIC16C717, PIC16C770 and

PIC16C771)

covered

this

data

sheet.

The

PIC16C717 device comes in 18/20-pin packages and

the PIC16C770/771 devices come in 20-pin packages.

The following two figures are device block diagrams of

the PIC16C717 and the PIC16C770/771.
