Overview

The Infineon FM25CL64B-DG is a 64Kbit (8K x 8) non-volatile Ferroelectric RAM (FRAM) memory IC. It offers high-speed SPI interface operation up to 20 MHz and operates from a 2.7V to 3.6V supply. This FRAM provides excellent endurance and data retention characteristics, making it suitable for applications requiring reliable data logging.

Why Choose This Part

The FM25CL64B-DG offers superior endurance of 100 trillion read/writes, significantly outperforming traditional EEPROM. Its NoDelay writes ensure data is immediately non-volatile, eliminating the need for write buffers and power-loss detection circuitry. With 151-year data retention and low power consumption (3uA standby), it provides a robust and energy-efficient memory solution for critical data storage.

Applications

Data Logging
Ideal for frequently updated configuration settings or event logs in industrial controls, medical devices, and utility meters due to its high endurance and fast write speeds.
Embedded System Parameter Storage
Stores critical system parameters that need to persist through power cycles without the wear limitations of traditional EEPROM.
Point-of-Sale (POS) Systems
Maintains transaction data and system state, offering rapid data capture and non-volatility without battery backup for the memory.
Medical Devices
Provides reliable storage for patient settings, calibration data, and usage logs where data integrity and endurance are paramount.
Smart Utility Meters
Records consumption data and tamper events, benefiting from the FRAM's non-volatility, low power consumption, and high write endurance.
