< Although there are some software complexities, the hardware support need < for the single-supply Flash parts is simply providing a WE signal, just < like for an SRAM (but on a different pin, IIRC). What about 2816 or 2864 EEproms, easier to use than flash, single 5v too same footprint as 2716/6116(2kb) or 2764/6264(8kb). they are fairly cheap too. Like under 6$ from JAMECO or JDR. Allison
