Hi Languer,
do you have some sample of program to write byte byte on the follow memory by SPI? I ordered 23A256 (2 bank)
I receive data at 57600 I have about 170 us of time to write data in memory
thankyou

OnSemi also seems to max out at 32 Kbytes (N25S830HAS22I).

You would most likely operate both these options in "Sequential/Burst Mode".

RAMTRON has the FM25V05 which would allow 64 Kbytes. These do have a limit on the amount of write operations (since they do retain data after power is lost), although it is quite high.
