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@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)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature number) you are
using.

DEVICE OVERVIEW
This document contains device-specific information for
the following devices, operating in an ambient
temperature range between -40°C and +150°C:
• PIC18F25K80
• PIC18F26K80
• PIC18F45K80
• PIC18F46K80
• PIC18F65K80
• PIC18F66K80
The primary differentiating features and specifications
of the high-temperature PIC18F66K80 family devices
are:
• Above +125°C, writes are not allowed for Flash
program memory
• All AC timing specifications are increased by 15%
This derating factor includes parameters, such as
T
PWRT
• Maximum HS frequency of operation is 64 MHz
Note:
This data sheet documents only the devices’
features and specifications that are in
addition to the features and specifications of
the non-specialty PIC18F66K80 devices.
For information on the features and
specifications shared by this document’s high-
temperature devices and the non-specialty
devices, see the
