AN108 - Migrating from FM18L08 to FM28V020
AN108 discusses the key differences that need to be considered when migrating from FM18L08 to FM28V020.FM18L08 is now obsolete and this application note explains how FM28V020 is a replacement for FM18L08.
FM28V020, a 256-Kbit parallel F-RAM™, is a replacement device for FM18L08, which is now obsolete. For most designs, the FM28V020 device can be considered equivalent or better than the FM18L08. The two devices are identical in terms of pinout, package composition and dimensions, and read/write functionality. The FM28V020 also incorporates a page-mode feature that allows read/write operations up to 25 MHz. This application note discusses the key differences between the two devices that need to be considered when migrating from FM18L08 to FM28V020.
