MSP430 Flash Endurance

Leo Hendrawan

Team,

a customer is using MSP430F2618T and they are worried about the flash endurance. They are referring to SLAA334, and in chapter 3.2, you can find the statement:

"During endurance testing at Texas Instruments, the flash cells are continuously erased and rewritten. With a delay of at least one or two seconds between two erase/write cycles, the flash endurance increases significantly during the tests.”

Do we have any quantitative data what does "increases significantly" mentioned above? Does it mean we can expect the flash endurance to go beyond 10^5? If yes, what would be the approximate number?

Thanks.

    I will contact the involved members of these MSP430 endurance tests to see if any quantitative results can be recovered, but the material is so old that this might not be possible. At any rate, TI can make suggestions on how to improve flash program and erase endurance but cannot guarantee results outside of what is stated in the datasheet.

    Edit: This issue has been taken offline, where the conclusion is as stated above.

    Regards,
    Ryan
