High-performance FRAM memory chip, model FM24CL256B (market alias GD24CL256B), capacity 256Kbit / 32KB, I2C two-wire serial interface, maximum bus speed up to 1MHz.

Ultra-high write endurance up to 100 trillion cycles, far superior to ordinary EEPROM (only 1 million times), no write delay, real-time data writing without waiting.

Wide operating voltage range 2.7V–3.65V, ultra-low power consumption design, ideal for battery-powered portable devices, meters and sensors.

151-year long data retention without power supply, stable data storage in harsh working environment, with hardware write protection pin to avoid mis-erasure.

Standard SOP-8 / SOIC8 package, easy PCB mounting, fully pin-to-pin compatible with general 24 series EEPROM, widely used for parameter log storage.
