Product Overview

The Micron MT25QL256ABA8E12-1SIT is a high‑performance 256Mb (32MB) serial NOR Flash memory from the MT25Q family. Operating from a standard 2.7V to 3.6V power supply, it supports standard SPI, Dual SPI, and Quad SPI protocols, with a maximum clock frequency of 133 MHz in Single Transfer Rate (STR) mode [reference:0][reference:1][reference:2], delivering a read throughput of up to 90 MB/s [reference:3]. This makes it ideal for execute‑in‑place (XIP), fast booting, and code storage in industrial, networking, and embedded systems.

The device is organized as 32M x 8 (256Mb) [reference:4], with a flexible erase architecture: 64KB sectors, 4KB and 32KB subsectors. Housed in a compact 24‑ball T-PBGA (6x8mm) package [reference:5][reference:6], it operates over the industrial temperature range of -40°C to +85°C [reference:7][reference:8][reference:9]. With 100,000 program/erase cycles [reference:10] and 20‑year data retention [reference:11], the MT25QL256ABA 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: 133 Mbps
Compatible with all SPI hosts

Dual SPI (1-1-2)

2‑bit read: 266 Mbps
Good speed / pin trade‑off

Quad SPI (1-4-4)

4‑bit read: Up to 90 MB/s (720 Mbps)
Optimal XIP performance

The MT25QL256ABA supports QPI (Quad Peripheral Interface) mode where all commands and addresses are transmitted over 4 I/O lines. It also features Single Transfer Rate (STR) mode, 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 MT25QL256ABA 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. Hardware write protection (WP# pin) and software write protection with write enable latch are also supported.

⏸️ 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.
