Overview

The FM25V20A-GTR is a 2Mbit non-volatile memory IC utilizing ferroelectric RAM (FRAM) technology, which allows for high-speed writes without the typical write delays of Flash or EEPROM. It operates on a supply voltage between 2V and 3.6V and features a 40 MHz SPI interface. This 256K x 8 device is designed for high-reliability applications requiring frequent and fast data logging.

Why Choose This Part

This FRAM IC offers extreme endurance of 10^14 read/write cycles and a 151-year data retention period at 85C. Unlike Flash, it performs writes at bus speed without requiring a soak time or page buffering, and it consumes significantly less power with a 3uA sleep mode current.

Applications

Industrial Data Logging
Perfect for recording high-frequency sensor data where power might be lost unexpectedly, ensuring zero data loss due to NoDelay writes.
Configuration Storage
Ideal for storing system settings that are updated frequently, leveraging the 100 trillion cycle endurance.
Smart Metering
Used in utility meters to track usage in real-time without the risk of wearing out the memory cells compared to standard EEPROM.

Getting Started

Designers can interface this device using standard SPI Mode 0 or Mode 3. Since it behaves like an SRAM with non-volatile properties, no wear-leveling software is required; simply write to the desired address using the 02h Opcode. For hardware prototyping, ensure the WP pin is tied high if write protection is not required and verify the 0.209 inch wide 8-SOIC footprint matches your PCB layout.

Also Consider

MR25H40VDF Everspin Technologies - An MRAM alternative that offers similar non-volatile performance with high endurance and fast write speeds for critical systems.
FM25W256-GTR IFXInfineon Technologies - A smaller 256Kbit density option for cost-sensitive applications that still require the high endurance of FRAM.
