AN311 - FM25V01 Replaces Two FM25CL64s

Last Updated:

The FM25V01, a 128-Kbit SPI F-RAM, is a potential replacement for two FM25CL64 (64-Kbit) devices; FM25CL64 is now obsolete. For most designs, the FM25V01 device can be considered a superset of the FM25CL64. The two devices are identical in terms of pinout, package dimensions, and read/write functionality. This application note discusses the key differences between the two devices, apart from density, which need to be considered when migrating from FM25CL64 to FM25V01.
