Product Overview
The Micron MT25QL01GBBB8ESF-0SIT is a 1Gb (1,073,741,824 bits) high-performance serial NOR Flash memory from the MT25Q family. It is a stacked device consisting of two 512Mb dies in a single package[reference:0][reference:1]. Operating from a standard 2.7V to 3.6V power supply[reference:2][reference:3], it supports standard SPI, Dual SPI, and Quad SPI modes, with a maximum clock frequency of 133 MHz in Single Transfer Rate (STR) mode and 90 MHz in Double Transfer Rate (DTR) mode[reference:4][reference:5], delivering a read throughput of up to 90 MB/s[reference:6][reference:7]. 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 128M x 8 (1Gb)[reference:8][reference:9], with a flexible erase architecture: 64KB sectors and 4KB/32KB subsectors[reference:10][reference:11]. Housed in a standard 16‑pin SOP2 (300mil) package (SOIC-16 wide body)[reference:12][reference:13], it operates over the industrial temperature range of -40°C to +85°C[reference:14][reference:15]. With 100,000 program/erase cycles and 20‑year data retention[reference:16][reference:17], the MT25QL01GBBB delivers the endurance and reliability required for industrial control, communications, medical devices, and automotive aftermarket applications.

⚡ Quad SPI Performance & Modes
Compatible with all SPI hosts
Good speed / pin trade‑off
Optimal XIP performance[reference:74]
The MT25QL01GBBB 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:75].
🏗️ Stacked Die Architecture
The MT25QL01GBBB is a stacked device consisting of two 512Mb dies integrated into a single package[reference:76][reference:77]. This architecture enables high-density storage in a standard footprint while maintaining the performance and reliability characteristics of Micron's NOR Flash technology. The stacked die configuration is fully transparent to the system, with the device appearing as a single 1Gb memory array. This design approach allows for cost-effective high-density solutions without compromising on speed or endurance.
🔒 Security & Write Protection Features
🔑 Unique 64‑bit Device ID
Each MT25QL01GBBB 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[reference:84]. The OTP region can be locked permanently to prevent further writes.
🛡️ Flexible Write Protection
Volatile and nonvolatile locking for each 64KB sector[reference:85]. Nonvolatile configuration locking and password protection provide additional security layers[reference:86].
⏸️ 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[reference:87]. CRC detection protects against accidental changes to raw data[reference:88].
