17.8 High Temperature Operation
This section outlines the specifications for the following
devices operating in the high temperature range
between -40°C and 150°C.
(4)
•PIC16F685
•PIC16F687
•PIC16F689
•PIC16F690
When the value of any parameter is identical for both
the 125°C Extended and the 150°C High Temp.
temperature ranges, then that value will be found in the
standard specification tables shown earlier in this
chapter, under the fields listed for the 125°C Extended
temperature range. If the value of any parameter is
unique to the 150°C High Temp. temperature range,
then it will be listed here, in this section of the data
sheet.
If a Silicon Errata exists for the product and it lists a
modification to the 125°C Extended temperature range
value, one that is also shared at the 150°C High Temp.
temperature range, then that modified value will apply
to both temperature ranges.
TABLE 17-17: ABSOLUTE MAXIMUM RATINGS
Note 1: Writes are not allowed for Flash
program memory above 125°C.
2: All AC timing specifications are increased
by 30%. This derating factor will include
parameters such as T
PWRT.
3: The temperature range indicator in the
catalog part number and device marking
is “H” for -40°C to 150°C.
Example: PIC16F685T-H/SS indicates
the device is shipped in a Tape and reel
configuration, in the SSOP package, and
is rated for operation from -40°C to
150°C.
4: AEC-Q100 reliability testing for devices
intended to operate at 150°C is 1,000
hours. Any design in which the total oper-
ating time from 125°C to 150°C will be
greater than 1,000 hours is not warranted
without prior written approval from
Microchip Technology Inc.
5: Endurance of the data EEPROM
decreases with increasing temperature. It
is recommended that the number of pro-
gramming cycles to any individual
address at temperatures above +125°C
not exceed 25,000. Error correction tech-
niques are advised for data requiring
more programming cycles above +125°C.
6: DS80243 Table 1 refers to various revi-
sions of the PIC16F685, but operation
above +125°C will only be available for
revision A6 or later.
7: The +150°C version of the PIC16F685
will not be offered in PDIP. It will only be
offered in SSOP, SOIC, and QFN.

Note: Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the
device. This is a stress rating only, and functional operation of the device at those or any other conditions
above those indicated in the operation listings of this specification is not implied. Exposure above
maximum rating conditions for extended periods may affect device reliability.
