AN92577 compares the key features of the FM25H20 and FM25V20A devices. FM25H20 is now obsolete. This application note explains how FM25V20A is a replacement for FM25H20.
 

Introduction

The FM25V20A, a 2-Mb Serial (SPI) F-RAM™, is a replacement device for FM25H20, which is now obsolete. For most designs, the FM25V20A device can be considered a superset of the FM25H20. The two devices are identical in terms of pinout, package composition and dimensions, and read/write functionality. This application note compares the key features of the two devices and shows how FM25V20A is a replacement for FM25H20.
