Non-Volatile 64Kbit / 8KByte SPI FRAM Breakout
FRAM, or Ferroelectric Ram, is similar to Dynamic random-access memory, only with a ferroelectric layer instead of a dielectric layer. The SPI FRAM breakout board is excellent for low-power, inconsistent-power datalogging or data buffering where you want to stream data fast. This FRAM chip has 8 kilobytes of storage, interfaces using SPI, and can run at up to 20MHz SPI clock 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.
