How about two Ramtron FM18L08's? Nonvolatile
like core with no battery
to die or leak. Would need level shifters to 3.3 volts
and slightly different timing. Low power, and in DIP or SMT. I'm just
tired of cleaning boards that had batteries that leaked all over them.
How long will a supercap keep that much SRAM alive?
