The FM25V20A-DG is a 2-Mbit (256K × 8) serial F-RAM memory featuring advanced ferroelectric technology, supporting 100 trillion (10¹⁴) read/write cycles and 151-year data retention at 65°C. Operating from 2.0 V to 3.6 V across –40°C to +85°C, it offers up to 40 MHz SPI interface and NoDelay™ writes at bus speed. Low power consumption, robust write protection, and hardware drop-in compatibility make it ideal for frequent-write industrial controls and data logging.
