Yen Ting Chu

Part Number: MSP430FR5869

Hi Team,

When MCU powers off (system shut down happen), how to recover MCU backup data storage or pick up during SMT line down or happen in RD firmware upgrade? Any solution or document can provide or suggest? Thanks.

Best regards,

Hi Andy,

What type of data do you want to recover? Some critical parameters? You can leverage the fast access speed of FRAM to store and recover data when system shut down happen.

Please refer to below document and TI Reference Design:
