The new Xplained board is unpopulated, but has pads for AT45DB or AT25DF chips.
As far as I can see AT45DB chips are only in leadless packages. The AT25DF come in SOIC-8.
There does not appear to be a 64Mbit AT25DF chip.
Can anyone advise on a suitable chip?
RS have: these 64MB chips
As far as I can see, these chips all have similar commands. Just needs different command byte values to AT45DB commands.
