Overview

The MX25L6433FM2I-08G is a 64Mbit CMOS Serial Flash memory featuring a high-performance Quad I/O SPI interface capable of clock speeds up to 133 MHz. It is designed to provide high-speed data throughput and reliable non-volatile storage for embedded systems operating between 2.65V and 3.6V. The device supports Single, Dual, and Quad I/O modes to optimize bus bandwidth for various application requirements.

Why Choose This Part

The component offers high performance with 133 MHz Quad I/O operation, significantly reducing data access times compared to standard SPI. It includes advanced features like Program/Erase Suspend and Resume for flexible system management and a dedicated 8K-bit OTP security sector for unique device identification.

Applications

Embedded System Boot Code
Storing executable boot code for microcontrollers and SoCs that lack sufficient internal flash memory.
Configuration Storage
Managing FPGA bitstreams and system configuration parameters that require high-speed loading during power-up.
Data Logging
Recording sensor data or event logs in industrial and consumer devices where 64Mbits of non-volatile capacity is required.
