Note:
1. Eon EN25Q32A Flash can support the general standard / dual / quad SPI mode (Need specific SPI
controller), but don’t support the Vpp pin (Vpp = 9 V for Fast Program/Erase mode) and HOLD# pin
functions.
2. For the general standard / SPI mode, Eon EN25Q32A Flash is the same as NUMONYX M25P32 Flash
if customer don’t use the Vpp pin and HOLD# pin functions.
3. NUMONYX M25P32 doesn’t support the dual and quad SPI modes.
