Overview

The MX25U25645GMI00 is a high-performance 256Mbit CMOS Flash NOR memory IC featuring a Quad I/O SPI interface. It supports Double Transfer Rate (DTR) and Quad Peripheral Interface (QPI) modes to achieve high throughput for Execute-in-Place (XIP) applications. Operating on a low-voltage 1.8V rail, this device is optimized for power-sensitive designs requiring fast read performance up to 166 MHz.

Why Choose This Part

This memory IC offers exceptional throughput using DTR mode and 166 MHz clock speeds, significantly reducing boot times and latency. Its low voltage 1.65V to 2V supply range and 20uA standby current make it ideal for battery-operated devices. Furthermore, the 8K-bit security OTP and block lock protection provide hardware-level security for sensitive firmware.

Applications

Execute-in-Place (XIP) Storage
Used as external code memory for microcontrollers lacking sufficient internal flash, allowing code execution directly from the SPI bus.
FPGA Configuration
Stores bitstream data for high-density FPGAs that require fast loading times via Quad SPI at power-up.
High-Resolution Graphics Buffering
Provides storage for UI assets, fonts, and images in embedded display systems where fast burst-read access is critical.
Industrial Data Logging
Reliable non-volatile storage for system logs and calibration data in environments ranging from -40 to +85 degrees Celsius.

Getting Started

Engineers can interface this memory with any MCU or FPGA supporting standard SPI, Dual I/O, or Quad I/O protocols. Ensure the host controller logic levels are compatible with the 1.8V supply to avoid damage. Development typically involves using a standard SPI flash driver and configuring the device's status registers for the desired I/O mode.
