Hi,

I am looking for 512k(64k x 8) nvram, but can't seem to source it. Does anybody have a link, assuming it exists?

I found SPI chips, but I can't find parallel sram as nvram.

p.s. I have this: ds1230y 256k(32k x 8) nvram.

Thanks, Kei

Have you considered using SRAM with battery backup?
Also, don't ignore a flash memory card.
Thanks, Mr. Chips, yes I have thought of that but if you have to swap from arduino programmer to computer circuit it is not easy, at least until I make a circuit for loading a program from other media to battery backed up ram (in-circuit programming).
