Page1/5 Migration from EN25P32 to EN25F32 Part No. : EN25F32 Issued date : 2008 / 12/ 18 Prepared by : FAE engineer: Dragon Chiang Approval by : FAE Manager: Jason Tseng This Application Note may be revised by subsequent versions or modifications due to changes in technical specifications. ©2005 Eon Silicon Solution Inc. www.eonssi.com.tw Rev. A, Issue Date: 2008/ 12/ 18 Eon Silicon Solution Inc. Page2/5 1. Purpose EN25P32 will EOL and be replaced by EN25F32 which can offer uniform 4Kbytes sector and allow for greater flexibility in applications. This note highlights the difference between those two devices. And it helps customers to migrate into new device. 2. Difference When customers want to replace EN25P32 with EN25F32, the difference of device ID needs to take care only. Other items in the list below are the additional features of EN25F32 compared with EN25P32.
