Cypress Semiconductor Corporation • 198 Champion Court • San Jose, CA 95134-1709 • 408-943-2600 Document Number: 001-86149 Rev. *A Revised May 07, 2013 FM25CL64B – Automotive Temp. 64Kb Serial 3V F-RAM Memory Features 64K bit Ferroelectric Nonvolatile RAM Organized as 8,192 x 8 bits High Endurance 10 Trillion (10 13) Read/Writes NoDelay™ Writes Advanced High-Reliability Ferroelectric Process Fast Serial Peripheral Interface - SPI Up to 16 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 3.0-3.6V 6 A Standby Current (+85 C) Industry Standard Configuration Automotive Temperature -40 C to +125 C o Qualified to AEC Q100 Specification “Green”/RoHS 8-pin SOIC Description The FM25CL64B is a 64-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or FRAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 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 transferred to the device. The next bus cycle may commence without the need for data polling. The FM25CL64B is capable of supporting 10 13 read/write cycles, or 10 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 automotive 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 FRAM technology. Device specifications are guaranteed over the automotive temperature range of -40°C to +125°C.
