Standby Current Industry Standard Configuration Industrial Temperature -40 C to +85 C 8-pin “Green”/RoHS SOIC (-G) Description The FM24C04C is a 4-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or FRAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 36 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. The FM24C04C performs write operations at bus speed. No write delays are incurred. Data is written to the memory array in the cycle after it has been successfully transferred to the device. The next bus cycle may commence immediately without the need for data polling. The FM24C04C is capable of supporting 10 12 read/write cycles, or a million times more write cycles than EEPROM. These capabilities make the FM24C04C 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 combination of features allows more frequent data writing with less overhead for the system. The FM24C04C provides substantial benefits to users of serial EEPROM, yet these benefits are available in a hardware drop-in replacement. The FM24C04C is available in an industry standard 8-pin SOIC package and uses a familiar two-wire protocol. The specifications are guaranteed over the industrial temperature range from -40°C to +85°C.
