512 bytes of non-volatile, ultra-lower power memory via I2C, which directly replaces EEPROM and FLASH.
FRAM is short for Ferroelectric RAM. This module is non-volatile (retains data without power) and is a drop-in replacement for EEPROM and Flash on an I2C Bus.
We have a free Arduino Library, and ANSI C code examples available here: FRAM-X Code Examples
FRAM is backward compatible with EEPROM but with the following improvements:
- It's faster (1 ns read/write)
- Lower power (microamps at 3.3V)
- Orders of magnitude greater write-erase cycles
- Reference: http://en.wikipedia.org/wiki/Ferroelectric_RAM
Some project ideas include:
- Memory for robots to preserve previously acquired data
- Pre-computed look-up tables for complex mathematical functions
- Scratch memory to expand a processor's available RAM
This Add-on comes with 3 address election switches as well as a write-disable switch. Pin compatible chips are also available in higher memory densities.
