MT25QU128ABB8E12-0AUT

MT25QU128ABB8E12-0AUT is Micron’s 128-Mbit Quad I/O SPI NOR flash memory (MT25QU family). It provides nonvolatile storage for embedded systems with SPI and Quad SPI interfaces, enabling fast code boot and data storage over a low-pin count bus. Key features typically include fast read via Quad SPI, page-program and sector/block erase, hardware write protection and security options, deep power-down, and XIP (execute-in-place) capability. The device operates from a single supply in the mid-voltage range (commonly 2.7–3.6V) and is offered in small package variants suitable for embedded, automotive, and industrial applications. The -AUT suffix generally indicates an automotive temperature-grade variant. Typical use cases include microcontroller firmware storage, firmware updates, and data logging. For exact timing, endurance, sector/page sizes, voltage ranges, and packaging, refer to the MT25QU128ABB8E12-0AUT datasheet.
