Standby Current Industry Standard Configuration • Industrial Temperature -40 ° C to +85° C • 8-pin “Green”/RoHS SOIC (-G) Description The FM25C160B is a 16-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile but operates in other respects as a RAM. It provides reliable data retention for 38 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. The FM25C160B performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after it has been successfully transferred to the device. The next bus cycle may commence immediately without the need for data polling. The FM25C160B is capable of supporting up to 10 12 read/write cycles, or a million times more write cycles than EEPROM. These capabilities make the FM25C160B 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 industrial controls where the long write time of EEPROM can cause data loss. The FM25C160B provides substantial benefits to users of serial EEPROM, in a hardware drop-in replacement. The FM25C160B uses the high-speed SPI bus, which enhances the high-speed write capability of F-RAM technology. The specifications are guaranteed over an industrial temperature range of -40°C to +85°C.
