TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and
enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via
E-mail at
docerrors@mail.microchip.com
or fax the
Reader Response Form
in the back of this data sheet to (480) 792-4150.
We welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
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).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision
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) 792-7277
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 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 by 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.
