CDCE913: Data Retention

Part Number: CDCE913

Hi,

"Data Retention" is specified on the datasheet.

・Is counting started from writing?

・Is this specification condition Ta=85℃ and 100 programming cycle?

・Do you have reference data on different condition?

  (My customer requests 60℃ and 10 programming cycle.)

Best Regards,

Kuramochi

    Hi Kuramochi,

    I'm afraid we don't have further data for EEPROM retention time. All we can tell is that the minimum retention time is 10 years under the worst operating conditions (85 degC)

    Hao-san,

    Thank you for your reply.

    I change question.

    After 100 programming cycle, data retention is guaranteed 10 years at 85℃ condition, right?

    Hi Kuramochi-san,

    Yes EEPROM retention time is at least 10 years at 85 deg C after <=100 programming cycles.

    Hi,

    Thank you for your support.

    Is counting retention started from 1st writing?

    Hello,

    Yes this counting is from first customer writing = 1.
