Mikroe EERAM 3 Click

Mikroe EERAM 3 Click has EERAM memory to retain data during power loss without external batteries. The board features the Microchip Technology 48L256 serial EERAM with SRAM memory core, including hidden EEPROM backup. 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).
