Ramtron International Corp FM25H20: 2-Mbit serial FRAM has a high-speed SPI

Manufactured on a 130-nm-CMOS process, the 2-Mbit FM25H20 serial FRAM provides a high-speed SPI (serial-peripheral interface). The high-density nonvolatile memory suits serial-flash replacement. Organized as a 256-kbit×8-bit nonvolatile memory, the device draws 1 mA for reads/writes at 40-MHz bus speeds, 80 mA in standby, and 3 mA in ultralow-current sleep mode. The retains data for 10 years, has a hardware- and software-write-protection feature, claims unlimited endurance, and operates at 2.7 to 3.6V over a –40 to +85°C temperature range. The device complies with ROHS (restriction-of-hazardous-substances) directives and has an SOIC-8 footprint. Available in a 5×6-mm TDFN-8 package, the FM25H20 costs $10.20 (10,000).
