MX25L25645GM2I-08G
Overview
The MX25L25645GM2I-08G is a high-performance 256Mbit CMOS MXSMIO (Serial Multi I/O) Flash memory organized as 32M x 8. It supports Single, Dual, and Quad I/O modes along with Double Transfer Rate (DTR) and Quad Peripheral Interface (QPI) for high-speed data throughput up to 133MHz. Operating from a 2.7V to 3.6V supply, this NOR flash is designed for systems requiring fast boot times and execute-in-place (XIP) capabilities.
Why Choose This Part
This device offers exceptional flexibility with its DTR and QPI modes, achieving high read performance that rivals parallel flash interfaces while maintaining a small 8-SOP footprint. It features 4KB uniform sectors and larger 32KB/64KB blocks for efficient erase management, alongside a 256-byte page buffer for fast programming. Reliability is enhanced by 100,000 erase/program cycles, latch-up protection up to 100mA, and a dedicated 4K-bit secure OTP area for sensitive identifiers.
Applications
Key Specifications
Getting Started
To interface with the MX25L25645G, configure your microcontroller SPI peripheral for Mode 0 or Mode 3 and ensure the 2.7V to 3.6V supply is stable. Engineers should consult the Serial Flash Discoverable Parameters (SFDP) table within the device to automatically detect timing and instruction sets. Software development can be accelerated using standard SPI-NOR drivers found in frameworks like Zephyr RTOS or the Linux MTD (Memory Technology Device) subsystem.
