Product Overview

The Micron MT25QU128ABA8ESF-0SIT is a 128Mb (16,777,216 bytes) high-performance serial NOR Flash memory from the MT25Q family. Operating at a low voltage of 1.7V to 2.0V (1.8V nominal)[reference:6], 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 Single Transfer Rate (STR) mode and 90 MHz in Double Transfer Rate (DTR) mode, delivering a read throughput of up to 166 MT/s[reference:7][reference:8].

The device is organized as 16M x 8 (128Mb), with a flexible erase architecture: 64KB sectors, 4KB and 32KB subsectors. Housed in a standard 16‑pin SOIC (300mil) package[reference:9], it operates over the industrial temperature range of -40°C to +85°C[reference:10]. 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 applications.

⚡ Quad SPI Performance & Modes

Standard SPI (1-1-1)

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

Dual SPI (1-1-2)

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

Quad SPI (1-4-4)

4‑bit read: 166 MT/s (166 MB/s)
Optimal XIP performance[reference:30]

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.

🔒 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
Volatile and nonvolatile locking for each 64KB sector. Nonvolatile configuration locking and password protection provide additional security layers.

⏸️ 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.
