Overview

The FM24CL16B-GTR is a 16Kbit ferroelectric RAM (F-RAM) non-volatile memory device that operates from 2.7V to 3.65V. Unlike standard EEPROM, F-RAM performs write operations at bus speed with no internal write delays and offers extreme endurance of up to 100 trillion read/write cycles. It serves as a high-reliability, hardware-compatible replacement for serial I2C EEPROMs in systems requiring frequent data logging.

Why Choose This Part

The primary advantage is the 100 trillion cycle endurance, which effectively eliminates wear-out concerns common in flash-based storage. It features ultra-low power consumption with a 3uA standby current and supports I2C clock frequencies up to 1 MHz.

Applications

Continuous Data Logging
Ideal for recording high-frequency sensor data or system state changes where EEPROM endurance limits would be exceeded.
Configuration Storage
Used to store critical user settings or calibration constants that must be updated instantly and retained through power loss.
Power-Fail Event Recording
The NoDelay write capability ensures that critical last-gasp data is captured immediately before a system power-down is complete.

Getting Started

Integration is straightforward as the device uses standard I2C protocol and is a direct socket replacement for many 24C16 EEPROMs. For development, use any I2C-enabled microcontroller and ensure the pull-up resistors are sized for your target bus speed, up to 1 MHz.
