Note:
1. If customers don’t use Hold# pin function on AT25DF321A, which can be replaced by EN25Q32A in
standard SPI mode.
2. Eon EN25Q32A Flash can support the general standard / dual / quad SPI mode (Need specific SPI
controller).
3. For general and dual SPI modes, Eon EN25Q32A Flash is the same as Atmel AT25DF321A Flash if
customer don’t use the HOLD# pin function.
4. Atmel AT25DF321A doesn’t support quad SPI mode.
5. If customers will use the VDFN (UDFN) package, please take care the dimensions of thickness “A”.
