From: CHollman82 on
Due to supply issues I am looking for an SPI flash memory chip >=64mbit to
replace the Atmel AT45DB642D "DataFlash".

I have found several possibilities from Winbond, SST, Spansion, and Samsung
but none of them offer the user accessible SRAM buffers that the Atmel part
has, nor do they allow page size erase operations (only sector erase, page
write).

I know it's a long shot but I was just wondering if anyone knew of a
similar serial flash chip with page erase capability, preferably with on
board page buffers.

Thanks.
