Microchip Technology announced a new family of Serial Peripheral Interface (SPI) EERAM memory products. The family is highlighted by four reliable SPI densities to Microchip's EERAM portfolio, ranging from 64 Kb to 1 Mb.

EERAM is a standalone nonvolatile RAM memory that uses the same SPI and I2C protocols as serial SRAM, enabling devices to retain SRAM content during power loss without using an external battery. When the device detects power leaving, it automatically transfers the SRAM data to nonvolatile storage and moves the data back once power returns to the part. In manufacturing lines, for example, stations handle up to millions of tasks over their lifetimes, and lost data during a task can require overhauling or discarding items. EERAMs automatically store SRAM content in these settings, allowing the manufacturing line to resume where the task was disrupted.
