Addendum
High Temperature Operation (125°C)
This data sheet addendum is to be used in conjunction with the existing AT25DF041B
datasheet specifications. The Adesto AT25DF041B 4Mbit Serial Flash devices will
operate @ 125°C with the following datasheet caveats. All other parameters will meet
the existing datasheet specifications.
The ordering code suffix (CAN# Code) 'HR' or ‘HT’ must be used to ensure correct
operation at this extended temperature range. Adesto will not modify and republish the
current datasheet to reflect the CAN# ordering code or the above caveats. The
standard AT25DF041B datasheet is available at http://www.adestotech.com.
