The FM24W256-GTR is a 256-kbit (32KB) ferroelectric random access memory (FRAM) device that is designed for non-volatile storage. Unlike traditional flash memory, FRAM enables high-speed read and write operations with virtually unlimited write cycles, making it suitable for applications where data integrity is critical. Functions - Non-Volatility: Retains data without a power supply. - High Endurance: Supports a virtually unlimited number of write cycles (typically over 10 trillion). - Fast Read/Write Speed: Offers fast data access and low latency compared to EEPROM and flash memory. - Low Power Consumption: Uses significantly less power than traditional memory technologies during operations. - Analog Signal Processing: Can be used in specific applications for data acquisition where non-volatility and write endurance are key. Applications - Data Logging: Ideal for applications that require frequent data writes and need to preserve data after power failure. - Industrial Controls: Used in control systems requiring robust data retention. - Smart Metering: Suitable for energy metering applications for retaining configurations and historical data. - Consumer Electronics: Utilized in devices where high reliability and low power consumption are necessary. - Automotive Applications: Employed in applications requiring reliable electronic systems and data retention despite harsh environments. Alternative Parts - FRAM Alternatives: - FM25V20-GTR: A smaller capacity FRAM with 2Mbit. - MB85RS256: 256kbit FRAM from Fujitsu (Fujitsu Semiconductor). - EEPROM Alternatives: - AT24C256: EEPROM with similar capacity and multiple write cycles but with lower endurance. - M24128: EEPROM with built-in page write capabilities. Embedded Modules - Microcontroller Integration: Often integrated with microcontrollers in embedded systems that require high-speed data logging and retention without the overhead of file systems. - Sensor Data Processing: Used alongside sensor modules to store configuration and sensor data in applications like IoT devices.
