A ferroelectric random access memory or FRAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. Unlike serial EEPROMs, the FM25CL64 performs write operations at bus speed. No write delays are incurred. The next bus cycle may commence immediately without the need for data polling. The next bus cycle may start immediately. In addition, the product offers virtually unlimited write endurance, orders of magnitude more endurance than EEPROM. Also, FRAM exhibits much lower power during writes than EEPROM since write operations do not require an internally elevated power supply voltage for write circuits. These capabilities make the FM25CL64 ideal for nonvolatile memory applications requiring frequent or rapid writes. Examples range from data collection, where the number of write cycles may be critical, to demanding automotive controls where the long write time of EEPROM can cause data loss. The FM25CL64 provides substantial benefits to users of serial EEPROM as a hardware drop-in replacement. The FM25CL64 uses the high-speed SPI bus, which enhances the high-speed write capability of FRAM technology. Device specifications are guaranteed over an automotive temperature range of -40°C to +125°C.
