hi
does anyone know of any micro controller which can give me a battery backup on the inbulit RAM?
i need to store some values into the RAM through some MMI and want them to be avaliable everytime on power up without re-entering the values.
i could use external NV RAM with battery backup but then i'd have to use port 0,2 for addressing and i would like to keep it for I/O.
any ideas? appreciate it.
ali
