Product Overview
The Micron MT25QU128ABA1EW9-0SIT is a 128Mb (16,777,216 bytes) high-performance serial NOR Flash memory from the MT25Q family[reference:0]. Operating at a low voltage of 1.7V to 2.0V (1.8V nominal)[reference:1][reference:2], this device is optimized for advanced embedded systems requiring large code storage, execute‑in‑place (XIP), and fast data access. It supports standard SPI, Dual SPI, and Quad SPI interfaces[reference:3]，with a maximum clock frequency of 166 MHz in Single Transfer Rate (STR) mode, delivering a read throughput of 166 MT/s[reference:4][reference:5].
The device is organized as 16M x 8 (128Mb)[reference:6][reference:7], with a flexible erase architecture: 64KB sectors, 4KB and 32KB subsectors. Housed in a compact 8‑pad WPDFN (8x6mm) package[reference:8][reference:9], it operates over the industrial temperature range of -40°C to +85°C[reference:10][reference:11]. With 100,000 program/erase cycles[reference:12] and 20‑year data retention, the MT25QU128ABA delivers the endurance and reliability required for industrial control, networking, medical devices, and automotive applications.

⚡ Quad SPI Performance & Modes
Compatible with all SPI hosts
Good speed / pin trade‑off
Optimal XIP performance[reference:48]
The MT25QU128ABA supports QPI (Quad Peripheral Interface) mode where all commands and addresses are transmitted over 4 I/O lines. It features a high-speed SPI-compatible bus interface, execute-in-place (XIP) functionality, and advanced write protection mechanisms[reference:49].
🔒 Security & Write Protection Features
🔑 Unique 64‑bit Device ID
Each MT25QU128ABA is factory‑programmed with a unique serial number, enabling device authentication, anti‑counterfeiting, and simple inventory tracking.
📦 64‑byte OTP (One‑Time Programmable) Register
A dedicated OTP area outside the main memory for permanent storage of encryption keys, serial numbers, or manufacturing data. The OTP region can be locked permanently to prevent further writes.
🛡️ Flexible Write Protection
Hardware write protection (WP# pin) and software write protection with write enable latch. Volatile and nonvolatile locking for each 64KB sector provide additional security layers[reference:50].
⏸️ Program/Erase Suspend & CRC Protection
During a long erase operation, the host can issue a suspend command, perform a read from another sector, and then resume the erase without data corruption. CRC detection protects against accidental changes to raw data.
