MCHPUSB2642-I/ML
Overview
The USB2642-I/ML is a high-performance USB 2.0 hub controller with an integrated flash media card reader and an Ultra Fast interface. It enables seamless bridging between a USB host and multiple storage formats including SD, MMC, and Memory Stick, while also providing downstream I2C and SPI connectivity. Designed for the industrial temperature range of -40C to 85C, it is suitable for robust embedded storage applications.
Why Choose This Part
The USB2642-I/ML features Microchip's Multi-Port Full-Speed Buffering (PHYBoost) and TrueSpeed technology for optimized signal integrity and data throughput. It integrates an internal 3.3V to 1.2V regulator, reducing external BOM count and simplifying the power delivery network in space-constrained 48-pin QFN designs.
Applications
Key Specifications
Getting Started
Development begins with Microchip's ProTouch configuration software, which allows engineers to customize the device's internal ROM and GPIO settings. Hardware evaluation can be performed using the EVB-USB2642 evaluation board, and hardware designers should ensure 3.3V VDD stability within the 3V to 3.6V range.
