The FM25V10-DGTR is a 1-Mbit (128K × 8) serial F-RAM memory with SPI interface, supporting 100 trillion (10¹⁴) read/write cycles and 151-year data retention at 65°C. Operating from 2.0 V to 3.6 V and up to 40 MHz, it features low active (300 μA at 1 MHz), standby (90 μA typ), and sleep (5 μA) currents. Housed in an 8-pin DFN package, it supports –40°C to +85°C and advanced write protection, making it ideal for frequent nonvolatile writes in industrial applications.
