(800) 545-FRAM, (719) 481-7000 http://www.ramtron.com Rev. 1.2 Feb. 2011 Page 1 of 14 FM25CL64B 64Kb Serial 3V F-RAM Memory Features 64K bit Ferroelectric Nonvolatile RAM • Organized as 8,192 x 8 bits • High Endurance 100 Trillion (1014) Read/Writes • 38 Year Data Retention (@ +75ºC) • NoDelay™ Writes • Advanced High-Reliability Ferroelectric Process Very Fast Serial Peripheral Interface - SPI • Up to 20 MHz Frequency • Direct Hardware Replacement for EEPROM • SPI Mode 0 & 3 (CPOL, CPHA=0,0 & 1,1) Sophisticated Write Protection Scheme • Hardware Protection • Software Protection Low Power Consumption • Low Voltage Operation 2.7-3.65V • 200 µA Active Current (1 MHz) • 3 µA (typ.) Standby Current Industry Standard Configuration • Industrial Temperature -40 °C to +85°C • 8-pin “Green”/RoHS SOIC and TDFN Packages Description The FM25CL64B is a 64-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 38 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. The FM25CL64B performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after each byte has been successfully transferred to the device. The next bus cycle may commence immediately without the need for data polling. In addition, the product offers substantial write endurance compared with other nonvolatile memories. The FM25CL64B is capable of supporting 1014 read/write cycles, or 100 million times more write cycles than EEPROM. These capabilities make the FM25CL64B 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 FM25CL64B provides substantial benefits to users of serial EEPROM as a hardware drop-in replacement. The FM25CL64B uses the high-speed SPI bus, which enhances the high-speed write capability of F-RAM technology. Device specifications are guaranteed over an industrial temperature range of -40°C to +85°C.
