PIC18F66K80 FAMILY
1.0 DEVICE OVERVIEW
This document contains device-specific information for
the following devices, operating in an ambient
temperature range between -40°C and +150°C:
This family of devices offers the advantages of all
PIC18 microcontrollers; namely, high computational
performance at an economical price. In addition to these
features, the PIC18F66K80 family introduces design
enhancements that make these microcontrollers a logical
choice for many high-performance, power-sensitive
applications.
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
• PIC18F25K80 • PIC18F46K80
• PIC18F26K80 • PIC18F65K80
• PIC18F45K80 • PIC18F66K80
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 “PIC18F66K80 Family Data
Sheet” (DS39977).
Note: The test duration for AEC-Q100 reliability
testing for devices operating at +150°C is
1,000 hours. Any design operating at
+125°C to +150°C for longer than that
period is not warranted without prior written
approval from Microchip Technology Inc.
