FM25640B-GATR

F-RAM 64Kb Serial SPI 5V FRAM 64-Kbit (8 K × 8) Serial (SPI) Automotive  F-RAM

Functional Description

The FM25640B-GATR FM25640B is a 64-Kbit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes similar to a RAM. It provides reliable data retention for 121 years while eliminating the complexities, overhead, and system level reliability problems caused by serial flash, EEPROM, and other nonvolatile memories.

Unlike serial flash and EEPROM, the FM25640B-GATR FM25640B performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after each byte is successfully transferred to the device. The next bus cycle can commence without the need for data polling. In addition, the product offers substantial write endurance compared with other nonvolatile memories. The FM25640B is capable of supporting 1013 read/write cycles, or 10 million times more write cycles than EEPROM.
