IFXFM25V02A-G
Overview
The FM25V02A-G is a 256Kbit non-volatile memory IC utilizing Ferroelectric RAM (F-RAM) technology, which combines the speed of SRAM with the persistence of Flash. It operates over a 2V to 3.6V supply range and features an SPI interface capable of clock speeds up to 40 MHz. Unlike standard EEPROM, this device offers NoDelay writes and extremely high endurance for data-logging applications.
Why Choose This Part
The primary advantage is its endurance of 100 trillion read/write cycles, which effectively eliminates wear-out concerns in most embedded designs. It also features 151-year data retention and significantly lower power consumption than serial flash, drawing only 2.5mA at 40MHz.
Applications
Key Specifications
Getting Started
To integrate this part, configure your MCU SPI peripheral for Mode 0 or Mode 3. Since F-RAM writes at bus speed without a polling period, you can simplify your driver code by removing the 'write-in-progress' polling loops required for EEPROM. For prototyping, the 8-SOIC package is compatible with standard SOIC-to-DIP adapter boards.
