MT25QU128ABA8ESF-0SIT – Serial NOR Flash – Micron

The Micron MT25QU128ABA8ESF-0SIT is a 128Mb, 1.8V multiple-I/O (SPI/Dual/Quad) serial NOR flash memory in a 16-pin SOIC (300 mil) package, rated for the industrial -40 C to +85 C temperature range.

The MT25QU128ABA8ESF-0SIT is a 128Mb (128-megabit) serial NOR flash memory from Micron’s high-performance MT25Q family. The “U” designator indicates a 1.8V (1.7V to 2.0V) supply rail, and the device features a high-speed SPI-compatible bus interface with single and double transfer rate (STR/DTR) operation, execute-in-place (XIP) support, and advanced write protection. It is supplied in a 16-pin SOIC (300 mil wide) package and rated for the industrial temperature range, making it well suited to embedded code-storage and configuration-memory roles.

With Dual and Quad I/O command support, the MT25QU128ABA8ESF-0SIT delivers increased read and program throughput over standard single-bit SPI, while remaining backward compatible with traditional SPI controllers. The 128Mb array can be addressed as 128M x1, 64M x2, or 32M x4, giving designers flexibility across boot, firmware, and data-logging applications.
