FM25V05-G

FM25V05-G is a 512-Kbit (64K × 8) serial (SPI) F-RAM memory. It is a 512-Kbit non-volatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is non-volatile and performs reads and writes similar to RAM. It provides reliable data retention for 151 years while eliminating the complexities, overhead, and system-level reliability problems caused by serial flash, EEPROM, and other non-volatile memories. The FM25V05 is capable of supporting 10^14 read/write cycles, or 100 million times more write cycles than EEPROM. These capabilities make the FM25V05 ideal for non-volatile 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 serial flash or EEPROM can cause data loss. The FM25V05 provides substantial benefits to users of serial EEPROM or flash as a hardware drop-in replacement.
