FM24C64B-GTR

FM24C64B-GTR is a 64-Kbit (8K × 8) serial (I²C) F-RAM. It is a 64-Kbit 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 RAM. It provides reliable data retention for 151 years while eliminating the complexities, overhead, and system-level reliability problems caused by EEPROM and other non-volatile memories. Unlike EEPROM, the FM24C64B 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 non-volatile memories. The application includes a general-purpose motor drive - variating frequency and voltage, LED strips, and signage.
