Product Overview
The Micron MT25QL256ABA8ESF-0SIT is a 256Mb (32,768K x 8) serial NOR Flash memory from the high-performance MT25Q family[reference:0]. Operating from a standard 2.7V to 3.6V power supply[reference:1][reference:2], it supports standard SPI, Dual SPI, and Quad SPI modes, with a maximum clock frequency of 133 MHz in Quad I/O mode[reference:3][reference:4], delivering a read throughput of up to 90 MB/s[reference:5]. This makes it ideal for execute‑in‑place (XIP), fast booting, and code storage in industrial, networking, and embedded systems[reference:6].
The device is organized as 32,768 programmable pages of 256 bytes each, with a flexible erase architecture: 4KB sectors, 32KB/64KB blocks, and full chip erase[reference:7][reference:8]. Housed in a standard 16‑pin SOIC (300mil) package[reference:9][reference:10], it operates over the industrial temperature range of -40°C to +85°C[reference:11][reference:12]. With 100,000 program/erase cycles and 20‑year data retention[reference:13][reference:14], the MT25QL256ABA delivers the endurance and reliability required for industrial control, communications, medical devices, and automotive aftermarket applications[reference:15].

⚡ Quad SPI Performance & Modes
Compatible with all SPI hosts[reference:58]
Good speed / pin trade‑off[reference:59]
Optimal XIP performance[reference:60]
The MT25QL256ABA 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[reference:61], 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 for permanent storage of encryption keys, serial numbers, or manufacturing data. The OTP region can be locked permanently to prevent further writes[reference:62].
🛡️ Flexible Write Protection
The Block Protection bits (BP[3:0] and TB) allow software‑defined protection of up to 50% of the memory[reference:63]. When the hardware WP# pin is driven low, the status register becomes read‑only, preventing any modification to the protection scheme[reference:64].
⏸️ 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:65].
