Infineon Technologies FM31256-G

The Infineon FM31256-G is a 256Kb non-volatile FRAM (Ferroelectric Random Access Memory) capable of high-speed data storage with low power consumption. Unlike traditional EEPROM and Flash memory, FRAM offers faster write speeds, unlimited write-erase cycles, and low power operation, making it suitable for a variety of applications where reliability and performance are crucial. Functions: 1. Non-volatile Storage: Retains data without power, which is essential for applications where data persistence is required. 2. High Speed: FRAM technology allows for fast read and write operations, making it suitable for high-performance applications. 3. Low Power Consumption: Operates efficiently at low voltage levels, beneficial for portable and battery-operated devices. 4. Endurance: Supports an unlimited number of write cycles compared to traditional non-volatile memory like EEPROM. Applications: - Smart Meters: Data logging and storage in electricity meters. - Industrial Control Systems: Storing calibration data, configuration settings, and operational logs. - Consumer Electronics: In devices where reliable data retention is key, such as medical devices and home automation systems. - Automotive Applications: Used in systems that require reliable data storage in harsh conditions. - Telecommunications: Data storage in networking equipment. Alternative Parts: - Microchip Technology 25AA256: An alternate EEPROM with similar non-volatile characteristics, though typically slower. - STMicroelectronics M41T62: A real-time clock with non-volatile memory, offering time-stamping features. - Cypress Semiconductor CY15B106: Another FRAM option with different capacity and speed specifications. - Texas Instruments TMS320F28027: An embedded controller that includes flash memory alongside its operation. Embedded Modules: - Modules that integrate FRAM or similar non-volatile memory types based on specific microcontrollers or systems on a chip (SoC). - Evaluation kits or development boards designed for testing FRAM-based applications. - System-on-Module (SoM) configurations that package FRAM with necessary peripherals for embedded applications.
