FM25V01A FRAM

This platform supports an optional non-volatile Ferroelectric RAM (FRAM) device. The Cypress FM25V01A is a 16 KiB device, in a configuration not unlike an SPI EEPROM. However, the nature of FRAM means it is non-volatile, incredibly fast to write, and is specified with 100 trillion read/write cycles (per each of the 2048 sequential 8 byte rows) with a 150 year data retention. The device is connected to Linux and presents itself as a flat file that can be read and written like any standard Linux file.
