The FM25V20, a 2-Mbit Serial SPI F-RAM, is a replacement device for FM25H20; FM25H20 is an old part which is not recommended for new designs. For most designs, the FM25V20 device can be considered as a superset of the FM25H20. The two devices are identical in terms of pinout, package dimensions and composition, and read / write functionality. This application note discusses the key differences between the two devices which need to be considered when migrating from FM25H20 to FM25V20.
