Eon EN25Q40 Flash can support the general standard / dual / quad SPI mode (Need specific SPI controller), but don’t support the HOLD# pin functions. 2. For the general standard / SPI mode, Eon EN25Q40 Flash is the same as NUMONYX M25P40 Flash if customer don’t use the HOLD# pin functions. 3. NUMONYX M25P40 doesn’t support the dual and quad SPI modes.
