AN315 - Migrating from FM25C160 to FM25C160B
AN315 discusses the key differences that need to be considered when migrating from FM25C160 to FM25C160B.FM25C160 is now obsolete and this application note explains how FM25C160B is a replacement for FM25C160.
FM25C160B, a 16-Kbit SPI F-RAM™, is a replacement device for FM25C160, which is now obsolete. The two devices are identical in terms of pinouts and read/write functionality. In terms of speed, both operate up to 20 MHz and have the same timing specifications. This application note discusses the key differences between the two devices that need to be considered when migrating from FM25C160 to FM25C160B.
