DS-25DF021A–042D–11/2015

High Temperature Operation (125

This data sheet addendum is to be used in conjunction with the existing AT25DF021A

datasheet specifications. The Adesto AT25DF021A 2Mbit 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
