Adafruit 1895 Evaluation board 1 pc(s)

FRAM, or Ferroelectric Ram, is similar to Dynamic random-access memory, only with a ferroelectric layer instead of a dielectric layer. The I²C FRAM breakout board is excellent for low-power or inconsistent-power datalogging or data buffering. This particular FRAM chip has 32 KBytes of storage, interfaces using I²C, and can run at up to 1MHz I²C rates. Each byte can be read and written instantaneously (like SRAM) 10,000,000,000,000 times but will keep the memory for 95 years at room temperature. You can use this chip with either 3V or 5V power and logic. It comes in a breadboard-friendly breakout with a spare stick of 0.1" male header for soldering on.
