If customers don’t use HOLD# pin function on SST25VF016B, which can be replaced by EN25Q16 in standard SPI mode. 2. SST25VF016B can support general standard SPI mode. 3. EN25Q16 can support general standard / dual / quad SPI mode. (Need specific SPI controller) This Application Note may be revised by subsequent versions or modifications due to changes in technical specifications. 3 ©2005 Eon Silicon Solution Inc. Rev.
