Rumor has it that vrs may have mentioned these words:
I think the more compelling problems with FRAM
have to do with
availability and 3.3V buffering and such.
Gwarsh - then why not just order the 5V version? Unforch, the 1Mbit
parts are 3.3V only, but the 256 & 64Kbit parts (the FM 1808 & FM1608
respectively) have 5V versions in both 120ns & 70ns speeds.
