Overview

The FM24V02A-GTR is a 256Kbit I2C non-volatile Ferroelectric RAM (F-RAM) organized as 32K x 8. Unlike standard EEPROM, this memory technology offers NoDelay writes and superior endurance, making it ideal for systems that require frequent or rapid data logging. It operates over a 2V to 3.6V supply range and supports a high-speed I2C interface up to 3.4 MHz.

Why Choose This Part

The primary advantage is an endurance rating of 100 trillion read/write cycles, which far exceeds the limits of traditional non-volatile memory. It features NoDelay writes, allowing data to be written at full bus speed without needing a polling routine. Additionally, it offers a 151-year data retention period and very low active current, consuming only 1mA at 3.4 MHz.

Applications

Industrial Data Logging
Continuous recording of sensor data or system states where high write endurance is critical for long-term reliability.
Configuration Storage
Storing system settings that must be updated instantly without the write delays associated with EEPROM or Flash.
Last-Gasp Buffer
Capturing critical system state information immediately upon power failure thanks to its fast write speed and low power consumption.

Getting Started

To integrate this part, connect the SDA and SCL lines to an I2C-capable microcontroller and provide a stable 2.0V to 3.6V supply. Since it follows standard I2C EEPROM protocols but without the write-cycle delay, existing software drivers can often be reused by removing 'wait-for-write' loops. Use the Device ID feature to programmatically verify the manufacturer and product ID during system initialization.
