AN98047 discusses the key differences that need to be considered when migrating from FM25V02/FM25V01 to CY15B256Q/CY15B128Q Automotive F-RAM. FM25V02/FM25V01 is now "Not Recommended for New Designs"; this application note explains how CY15B256Q/CY15B128Q is a replacement for FM25V02/FM25V01.

Introduction

CY15B256Q/CY15B128Q, a 256-Kbit/128-Kbit Automotive SPI F-RAM™, is a replacement device for FM25V02/FM25V01, which is now “Not Recommended For New Designs”. The two devices are identical in terms of pinout, package composition and dimensions, and read/write functionality. This application note discusses the key differences between the two devices that need to be considered when migrating from FM25V02/FM25V01 to CY15B256Q/CY15B128Q.
