CDCEL913 EEPROM Write Endurance

Paul Meaney
Prodigy 20 points
Other Parts Discussed in Thread: CDCEL913

The CDCEL913 Datasheet lists EEcyc (Programming Cycles of EEPROM) as 100 (MIN) and 1000 (TYP). I am not sure how to interpret this in the context of EEPROM endurance.

The standard way of specifying EEPROM endurance is by specifying a MINIMUM number of programming cycles - this is guaranteed number of programming cycles that can be executed without affecting device reliability.

Following this, caan I take it that the CDCEL913 onboard EEPROM is guaranteed for 100 programming cycles only, with the 1000 typical number being irrelevant when taking a worst case design view?

Any help on this would be greatly appreciated.

 

Thanks and regards,

    Hello Paul,

    this specification is in fact 1000 cycles minimum. That is a datasheet error and we will correct this. Thanks for pointing this out.

    This means that it is save to write 1000 times to the EEPROM, whereas the write cycles to the Registers(RAM) is not limited.

    Best regards,

    Julian
