Overview

The FM25VN10-G is a 1Mbit non-volatile Ferroelectric RAM (F-RAM) organized as 128K x 8 bits, designed for high-performance data logging and state storage. Unlike standard EEPROM or Flash, it offers virtually unlimited endurance of 100 trillion cycles and performs write operations at full bus speed without requiring soak times or polling.

Why Choose This Part

The primary advantage is NoDelay writes, which eliminates the 5-10ms write delay found in EEPROM and allows for 40 MHz SPI operation for both reads and writes. It features exceptionally high endurance of 10^14 cycles and extremely low power consumption, drawing only 0.3mA at 1MHz and 5uA in sleep mode.

Applications

Industrial Data Logging
Continuous recording of sensor data or system state where frequent writes would quickly exceed the endurance limits of conventional EEPROM.
Configuration Storage
Reliable storage of system parameters that must be updated instantly and retained for over 150 years without power.
Unexpected Power Loss Recovery
Critical for systems that must capture a snapshot of current registers or variables immediately upon detecting a power failure before the supply rails drop.

Getting Started

To integrate this device, connect it via a standard 4-wire SPI interface to any 2V to 3.6V microcontroller. Since it functions as a direct hardware replacement for many serial Flash and EEPROM devices, existing SPI drivers can often be reused by removing the write-polling or delay loops after write commands.
