Applies to 2Mb SPI F-RAM Devices

This document points out the differences the FM25H20 and FM25V20 F-RAM devices. For most designs, the FM25V20 device can be considered a superset of the FM25H20. The two devices are identical in terms of pinout, package dimensions and composition, and read/write functionality. In terms of speed, both operate up to 40MHz from 2.7V < VDD < 3.6V and in addition the FM25V20 allows read/write operations down to 2.0V.
