AN304 - SPI Guide for F-RAM™

2021 年 3 月 02 日

AN304 provides the functional description, timing, and example code for SPI F-RAMs. It also gives a PSoC 3-based user module for SPI F-RAM.


The FM25xxx F-RAM product family employs an industry-standard 4-wire SPI interface. They are high-speed (up to 40 MHz), low-power, nonvolatile memory devices. SPI F-RAM densities start from 4 Kbit and extend up to 4 Mbit. This application note reviews the functional and timing aspects of these devices.
