The FM25V02A-DG is a 256-Kbit (32K × 8) serial ferroelectric random access memory (F-RAM) offering 100 trillion read/write cycles and 151-year data retention. Operating from 2.0 V to 3.6 V at -40°C to +85°C, it features a 40 MHz SPI interface for fast, NoDelay™ writes and immediate data persistence. Low power consumption, robust hardware and software write protection, and an 8-pin DFN package make it ideal for industrial controls and data logging.
