The FM25L04B-GTR from Infineon (formerly Cypress\/Ramtron) is a 4-Kbit (512×8) serial F-RAM nonvolatile memory with 100 trillion read\/write cycles, NoDelay writes, and 151-year data retention in an SOIC-8 package. Operating from 2.7V to 3.6V with SPI interface up to 20MHz, it is a direct EEPROM replacement.<\/p>\n
