http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number. e.g., DS30000A is version A of document DS30000.
New Customer Notification System
Register on our web site (www.microchip.com/cn) to receive the most current information on our products.
Errata
An errata sheet may exist for current devices, describing minor operational differences (from the data sheet) and recommended
workarounds. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revi-
sion of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
Microchip's Worldwide Web site; http://www.microchip.com
Your local Microchip sales office (see last page)
The Microchip Corporate Literature Center; U.S. FAX: (480) 786-7277
When contacting a sales office or the literature center, please specify which device, revision of silicon and data sheet (include liter-
ature number) you are using.

DEVICE OVERVIEW
This document contains device-specific information.
Additional information may be found in the PICmicro
TM
Mid-Range Reference Manual, (DS33023), which may
be obtained from your local Microchip Sales Represen-
tative or downloaded from the Microchip website. The
Reference Manual should be considered a comple-
mentary document to this data sheet, and is highly rec-
ommended reading for a better understanding of the
device architecture and operation of the peripheral
modules.
There are three devices (PIC16C717, PIC16C770 and
PIC16C771) covered by this datasheet. 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.
