Rev. A, Issue Date: 2010/ 02/02 www.eonssi.com Eon Silicon Solution Inc. 1. INTRODUCTION The application note introduces how to implement a system design from Numonyx M25P32 Flash to Eon EN25Q32A Flash. 2. GENERAL FUNCTION COMPARISON TABLE: 2.1 The following table highlights the major features of these two devices. Features EN25Q32A 2.7 ~ 3.6 M25P32 2.7 ~ 3.6 8-pins SOP 200mil 8 contact VDFN Except Vpp and HOLD# pin SO8W (208mil) VFQFPN8 6 x 5mm (MLP8) SPI frequency 100MHz (standard mode) 80MHz @ dual & quad mode 75MHz (standard mode) Secured Silicon Sector Region 512 Byte N/A Voltage Range Pin to Pin Compatible (standard SPI mode) Sector Architecture SPI mode Uniform 1024 sectors of 4K byte 64 blocks of 64K byte Mode 0 / Mode 3 Uniform 64 sectors of 64K byte Mode 0 / Mode 3 Minimum Endurance Cycle 100K 100K Package 8-pins SOP 150mil 8-pins SOP 200mil 8 contact VDFN 8-pins DIP SO16 (300mil) SO8W (208mil) VDFPN8 8 x 6mm (MLP8) VFQFPN8 6 x 5mm (MLP8) This Application Note may be revised by subsequent versions or modifications due to changes in technical specifications. 2 ©2005 Eon Silicon Solution Inc.

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.
