Mikroe nvSRAM 3 Click

Mikroe nvSRAM 3 Click features the Cypress Semiconductor CY14B101I 1-Mbit nvSRAM organized as 128K words of 8 bits each with a fully-featured real-time clock. The embedded elements incorporate QuantumTrap technology and provide highly reliable nonvolatile storage of data. It provides infinite read and writes cycles with an additional automatic backup switch. Data transfer, initiated by the user through I2C commands, from SRAM to the nonvolatile elements takes place automatically at Power-Down. On the other hand, during the Power-Up, data is restored to the SRAM from the nonvolatile memory.
