From smart meters to manufacturing lines, applications that require repetitive task data logging must be able to automatically restore content if power is disrupted during processing. Current low density (64 Kb to 1Mb) nonvolatile serial RAM (NVRAM) solutions used for these datalogs are typically the highest price-per-bit memory in the resulting end products. Microchip Technology Inc. announced a new family of Serial Peripheral Interface (SPI) EERAM memory products that offer system designers up to 25 percent cost savings over the current serial NVRAM alternatives. The family introduces four reliable SPI densities to Microchip’s EERAM portfolio, ranging from 64 Kb up 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. All nonvolatile aspects of the part are essentially invisible to the user (more info).
