Adafruit SPI Non-Volatile FRAM Breakout - 4 Mbit / 512 KBytes

FRAM, or Ferroelectric RAM, offers a stable, non-volatile data storage solution with dynamic responsiveness, enabling rapid data writing. Unlike traditional dynamic random-access memory, FRAM employs a ferroelectric layer to achieve faster write performance and lower power usage.

Perfect for applications needing reliable data retention, FRAM ensures each byte can be read and written 10 trillion times with instant access and 95-year memory preservation at room temperature. An SPI FRAM breakout board allows seamless integration into DIY projects, providing 4 Megabits (512 KBytes) of storage with SPI interface and 40 MHz clock rates.

Equipped with 3.3V logic level shifting and a regulator, this breadboard-friendly breakout supports both 3V and 5V power. Alternatives like 2 MBit, 64Kbit SPI, and I²C FRAM breakout boards expand compatibility and capacity options, while our guide provides schematics, datasheets, and sample code for easy implementation across platforms.
