Hi Chris,
I've used the AT45 serial flash part from Atmel, they are availble from 1Mbit (128kB) to 64Mbit (8Mb), all with the same serial interface.
It just so happens that there is a class in the cookbook that abstracts it as a 512 byte block interface, and a random access byte read/write interface. The latter is great if you want to treat it like slow RAM for generic non-volatile storage, the former is perfect if you want to sit FAT on top of it and run a filesystem.
I wrote the class a while ago, and know there are some improvements needed, mainly in using the SRAM buffers for block caching, to save doing a flash read-modify-write for every access.

Hello, Everyone.
I'm looking for a serial flash IC to store a few bitmaps in. However, I have no experience with any particular part. Can someone suggest a good part to use? >2MB would be nice.
