AT25DF041B 4-Mbit, 1.7V-3.6V Minimum SPI Serial Flash Memory DATASHEET (ADDENDUM) High Temperature Operation (125C) 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 125C 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 2.
