64K Bit 8K x 8 Serial SPI Automotive, 16MHz, 3V to 3.6V, SOIC, 8 Pin - 

CY15B064Q-SXE is a 64Kbit automotive F-RAM non-volatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is non-volatile 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 non-volatile memories. Unlike serial flash and EEPROM, the CY15B064Q 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 device. The next bus cycle can commence without the need for data polling. In addition, the product offers substantial write endurance compared with other non-volatile memories. The CY15B064Q is capable of supporting 101³ read/write cycles, or 10 million times more write cycles than EEPROM.
