Re: eprom kind

as long as you can burn 32k of data to the proper spot on the chip (like when using an SST512 chip)

Re: eprom kind

also look at chip speed of around 70-90 ns and if you want to burn more than once, make sure the chip is MTP (many time programmable) and not OTP (one time programmable)

The chips on my site are the most commonly used.

AT29C256 (discontinued, wont have much longer)
SST27SF512 (much more cost affective alternative to the AT29C)
