Eon EN25Q32A Flash can support the general standard / dual / quad SPI mode (Need specific SPI controller), but don’t support the acceleration (ACC) pin and HOLD# pin functions. 2. For the general standard / dual SPI mode, Eon EN25Q32A Flash is the same as MXIC KH25L3205D Flash if customer don’t use the accelerated (ACC) pin and HOLD# pin functions. 3. MXIC KH25L3205D don’t support the quad SPI mode.
