MSP430FR2433: FRAM write under power failure

Part Number: MSP430FR2433

Hi,

I have a question from my customer about FRAM write operation.
Suppose instantaneous power failure happens during FRAM write operation, what happens?
Are data written lost, guaranteed or corrupted?

Thanks and regards,
Koichiro Tashiro

    Hi Koichiro,

    Is there a specific case or issue
    Normally, FRAM is written in bytes. If there is a sudden power failure when writing, it should be able to save the data that has been written, but it may also encounter other problems. This needs to be decided according to actual use environment.

    Thanks!

    Best Regards

    Johnson
