Product Overview

The Micron MT25QU128ABA1EW7-0SIT is a 128Mb (16,777,216 bytes) serial NOR Flash memory from the high-performance MT25Q family. Operating at a low voltage of 1.7V to 2.0V (1.8V nominal), 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 modes, with a maximum clock frequency of 166 MHz in Quad I/O mode, delivering a read throughput of up to 90 MB/s.[reference:0][reference:1]

The device is organized as 65,536 programmable pages of 256 bytes each, with a flexible erase architecture: 4KB sectors, 32KB blocks, 64KB blocks, and full chip erase. Housed in a compact 8‑pad WPDFN (6x5mm) package (1EW7 suffix), it operates over the industrial temperature range of -40°C to +85°C.[reference:2][reference:3] With 100,000 program/erase cycles and 20‑year data retention, the MT25QU128ABA delivers the endurance and reliability required for industrial control, networking, medical devices, and automotive aftermarket applications.[reference:4]

⚡ Quad SPI Performance & Modes

Standard SPI (1-1-1)

Single I/O: 166 Mbps
Compatible with all SPI hosts

Dual SPI (1-1-2)

2‑bit read: 332 Mbps
Good speed / pin trade‑off

Quad SPI (1-4-4)

4‑bit read: 90 MB/s (720 Mbps)
Optimal XIP performance[reference:39]

The MT25QU128ABA supports QPI (Quad Peripheral Interface) mode where all commands and addresses are transmitted over 4 I/O lines. It also features Single and Double Transfer Rate (STR/DTR) modes, providing flexibility for high‑speed random access and enabling seamless execute‑in‑place (XIP) without code shadowing to RAM.[reference:40]

🔒 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.

📦 4K‑bit OTP (One‑Time Programmable) Register
A dedicated OTP area for permanent storage of encryption keys, serial numbers, or manufacturing data. The OTP region can be locked permanently to prevent further writes.[reference:41]

🛡️ Flexible Write Protection
The Block Protection bits allow software‑defined protection of up to 50% of the memory in 4KB increments. When the hardware WP# pin is driven low, the status register becomes read‑only, preventing any modification to the protection scheme.[reference:42]

⏸️ Program/Erase Suspend
During a long erase operation (up to 400ms for 64KB block), the host can issue a suspend command, perform a read from another sector, and then resume the erase without data corruption.[reference:43]
