Overview

The MX25L25645GXDI-08G is a high-performance 256Mbit CMOS Serial NOR Flash memory featuring a 120 MHz clock rate and support for Multi-I/O protocols. It provides flexible memory organization with 4K byte sectors and larger 32K/64K byte blocks, enabling efficient data management for embedded systems. This device supports high-speed data transfer through Quad Peripheral Interface (QPI) and Double Transfer Rate (DTR) modes for performance-critical applications.

Why Choose This Part

The device offers a peak read current of 16mA at 100MHz in DTR mode while maintaining a low 15uA standby current, making it suitable for power-conscious designs. Its support for Quad I/O and DTR modes significantly increases throughput compared to standard SPI Flash, while advanced security features like Solid Protect individual sector protection ensure data integrity.

Applications

Execute-in-Place (XIP) Storage
Ideal for storing firmware and executing code directly from Flash in high-performance embedded systems using Performance Enhance Mode.
Industrial Data Logging
Provides 256Mbit of non-volatile storage with 100,000 erase/program cycles and 20-year data retention for reliable long-term logging.
Network Equipment Configuration
Utilized in routers and switches for storing boot code and complex configuration files with high-speed 120 MHz access.

Getting Started

To integrate this part, ensure the SPI controller supports Quad I/O or QPI modes to maximize the 120 MHz throughput. Engineers should implement the 256-byte page buffer for efficient programming and use the configurable dummy cycles to optimize read performance based on the operating frequency. Evaluation can be performed using standard SPI flash programmers or high-end microcontrollers with dedicated QSPI peripherals.
