FM25W256-G

The FM25W256-G is a 256-kilobit non-volatile ferroelectric random-access memory (FRAM) chip designed by Ramtron, now part of Cypress Semiconductor. Unlike traditional non-volatile memories like EEPROM or Flash, FRAM offers faster write speeds, higher endurance, and lower power consumption. The FM25W256-G operates over a wide voltage range and supports a high-speed Serial Peripheral Interface (SPI), making it suitable for applications requiring efficient data logging and frequent write operations.
Key features include fast write speeds, with no write delays, and a virtually unlimited number of read/write cycles, typically over 10^14 cycles, enhancing reliability and longevity. The memory is organized as 32K x 8 bit, and it retains data even after power is removed, making it ideal for use in applications such as industrial control, metering, and automotive systems.
The chip's ability to operate at industrial temperature ranges and its compatibility with conventional SPI protocols make it easy to integrate into existing systems. The FM25W256-G is thus favored in scenarios where data integrity and endurance are critical.
