The The MikroElektronika's EERAM 3 Click is a compact add on board that contains EERAM memory designed to retain data during power loss without the aid of external batteries. This board features the 48L256, a serial EERAM with SRAM memory core, including hidden EEPROM backup from Microchip Technology. The 48L256 is structured as a 256-Kbit SRAM with EEPROM backup in each memory cell, where SRAM is organized as 32,768x8 bits and uses the SPI serial interface. It offers unlimited reads and writes, invisible to user data transfers on power loss, 100,000 backups data can be transferred 100,000 times, and data retention data is kept safe for 10 years minimum. This Click board is ideal for nonvolatile memory applications requiring frequent or rapid writes and unlimited endurance.
