A ferroelectric random access 14 High-endurance 100 trillion (10 ) read/writes memory or F-RAM is nonvolatile and performs reads and writes similar to a RAM. It provides reliable data retention for 151 years 151-year data retention (See Data Retention and Endurance on page 12) while eliminating the complexities, overhead, and system level reliability problems caused by serial flash, EEPROM, and other NoDelay writes nonvolatile memories. Advanced high-reliability ferroelectric process Very fast serial peripheral interface (SPI) Unlike serial flash and EEPROM, the FM25L16B performs write operations at bus speed. No write delays are incurred. Data is Up to 20 MHz frequency written to the memory array immediately after each byte is Direct hardware replacement for serial flash and EEPROM successfully transferred to the device. The next bus cycle can Supports SPI mode 0 (0, 0) and mode 3 (1, 1) commence without the need for data polling. In addition, the Sophisticated write protection scheme product offers substantial write endurance compared with other Hardware protection using the Write Protect (WP) pin nonvolatile memories. The FM25L16B is capable of supporting 14 Software protection using Write Disable instruction 10 read/write cycles, or 100 million times more write cycles Software block protection for 1/4, 1/2, or entire array than EEPROM. These capabilities make the FM25L16B ideal for nonvolatile Low power consumption memory applications requiring frequent or rapid writes. 200 A active current at 1 MHz Examples range from data collection, where the number of write 3 A (typ) standby current cycles may be critical, to demanding industrial controls where the Low-voltage operation: V = 2.7 V to 3.6 V DD long write time of serial flash or EEPROM can cause data loss. Industrial temperature: 40 C to +85 C The FM25L16B provides substantial benefits to users of serial EEPROM or flash as a hardware drop-in replacement. The Packages FM25L16B uses the high-speed SPI bus, which enhances the 8-pin small outline integrated circuit (SOIC) package high-speed write capability of F-RAM technology. The device 8-pin thin dual flat no leads (DFN) package specifications are guaranteed over an industrial temperature Restriction of hazardous substances (RoHS) compliant range of 40 C to +85 C.
