Overview

The FM24CL64B-DGTR is a 64-Kbit nonvolatile memory utilizing an advanced ferroelectric process to provide F-RAM performance with an I2C interface. Unlike standard EEPROM, this device performs write operations at bus speed with no write delays and offers significantly higher endurance of 100 trillion read/write cycles. It operates over a voltage range of 2.7V to 3.65V and is designed for applications requiring frequent or rapid data logging.

Why Choose This Part

This F-RAM device eliminates the 5ms to 10ms polling delay found in EEPROMs, allowing for 'NoDelay' writes at the full I2C bus speed up to 1 MHz. It features an extremely low standby current of 3 uA and an endurance rating of 10^14 cycles, making it ideal for battery-powered systems that perform constant data writes.

Applications

Industrial Data Logging
Continuous recording of sensor data where high write endurance is required to prevent memory wear-out over the product lifespan.
Configuration Storage
Storing system settings that must be updated frequently and retained reliably during power loss for up to 151 years.
Real-Time State Saving
Capturing critical system state information immediately before power failure without the write-cycle delays associated with flash or EEPROM.

Getting Started

To integrate the FM24CL64B, connect the SDA and SCL lines to any standard I2C master and ensure the 8-pin DFN package is correctly decoupled with a ceramic capacitor near the VDD pin. The device uses standard I2C protocol addressing, making it compatible with existing EEPROM software libraries with minimal modification to remove write-timer delays.
