F-RAM-Slide4

Common design problems engineers face are presented on this slide. Automotive infotainment systems must store settings, status, and navigation data on power loss. Soak Time from EEPROMS requires 5 ms of active power per Page Write. Soak Time requires additional capacitors or batteries to perform a Page Write on power loss, increasing system cost. Automotive infotainment systems exceed the 1-million-cycle Write Endurance limitation of EEPROMs. Wear leveling is required to improve EEPROM Write Endurance to support a 20-year automotive lifetime requirement. Wear leveling requires up to 8x the memory capacity and additional software, thus, increasing system cost. Automotive manufacturers require AEC-Q100-qualified non-volatile memories. Cypress’s F-RAM solves these problems. F-RAM requires no Soak Time, eliminating the need for additional capacitors or batteries to complete a Page Write on power loss. It also provides 100 trillion write cycles, eliminating the need for Wear Leveling. Cypress now offers AEC-Q100-qualified memories in volume. Therefore, Cypress F-RAM is a high-performance, high-reliability, low-cost replacement for EEPROMs in a fast-growing market.
