MT25QU128ABB8E12-0AUT

MT25QU128ABB8E12-0AUT is a 128‑Mbit Serial NOR flash memory in an 8‑pin package from the MT25QU family. It provides a Quad SPI (QSPI) interface with options for standard SPI and Dual/Quad I/O modes, enabling high‑speed reads and efficient firmware storage.
Key points
- Capacity: 128 Mbit (16 MB)
- Interface: Quad SPI (QPI supported), also operable in standard/Dual SPI modes
- Memory type: Non‑volatile flash for firmware/code and data storage
- Commands: Read/Fast Read, Quad Read, Page Program (256 bytes), Sector Erase (4 KB), Block Erase (64 KB), Chip Erase, Write Enable, etc.
- Organization and access: Optimized for fast random access and deterministic erase/program operations
- Features: Deep Power‑Down, hardware write protection and security options; power/voltage compatible with typical SPI ranges
- Applications: Microcontroller boot code, external code storage, and other embedded system firmware/data storage
- Notes: Check the exact datasheet for timing, voltage (2.7–3.6 V variants exist), endurance, and full command set for this specific part number.

It uses an 8-pin SOIC (SOP-8) package, Pb-free.

- Pin count: 8 pins (8-pin package).
- Function: 128-Mbit Quad SPI serial NOR flash memory (DQ0–DQ3 data I/O with CS, CLK, Vcc, and GND).
