Microchip Technology introduces Serial Peripheral Interface (SPI) EERAM memory products

December 2, 2019 — Microchip Technology announced a family of Serial Peripheral Interface (SPI) EERAM memory products. The family introduces four 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. When the device detects power going away, it automatically transfers the SRAM data to nonvolatile storage and moves it back to the SRAM 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.

The EERAM uses standard Complementary Metal-oxide-semiconductor (CMOS) and Flash processes. The EERAM family comes with Microchip’s customer-driven obsolescence practice, which helps ensure availability to customers for as long as needed.
