EERAMs automatically store SRAM content in these settings, allowing the manufacturing line to resume where the task was disrupted. 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. 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. All nonvolatile aspects of the part are essentially invisible to the user. The family introduces four reliable SPI densities to Microchip’s EERAM portfolio, ranging from 64 Kb up to 1 Mb.ĮERAM is a standalone nonvolatile RAM memory that uses the same SPI and I 2C protocols as serial SRAM, enabling devices to retain SRAM content during power loss without using an external battery. (NASDAQ: MCHP) today 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. 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. 02, 2019 (GLOBE NEWSWIRE) - 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.
