  • Are you powering the battery-backed RAM?

    By the way - if your program keeps variables that should survive a power loss, you must also write your application so it can detect if the RAM has valid content. There is no configuration bit available that will magically tell if the RAM has been initialized or not, or if the power loss has been too long so a supercap has discharged too low.
