DS-25DF041B–040C–8/2017

Addendum

High Temperature Operation (125

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
