A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 10 years while eliminating the plexities, overhead, and system level reliability problems caused by Serial Flash and other nonvolatile memories. Unlike Serial Flash, the FM25V05 performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after it has been transferred to the device. The next bus cycle may mence without the need for data polling. The product offers very high write endurance, orders of magnitude more endurance than Serial Flash. Also, F-RAM exhibits lower power consumption than Serial Flash. These capabilities make the FM25V05 ideal for nonvolatile memory applications requiring frequent or rapid writes or low power operation. Examples range from data collection, where the number of write cycles may be critical, to demanding industrial controls where the long write time of Serial Flash can cause data loss. The FM25V05 provides substantial benefits to users of Serial Flash as a hardware drop-in replacement. The devices use the high-speed SPI bus, which enhances the high-speed write capability of F-RAM Device ID and Serial Number Device ID reads out Manufacturer ID & Part ID Unique Serial Number (FM25VN05) Low Voltage, Low Power Low Voltage Operation 2.0V - 3.6V 90 A Standby Current (typ.) 5 A...
