MCHPUSB5744/2G
Overview
The USB5744/2G is a high-performance, low-power USB 3.2 Gen 1 (formerly USB 3.0) hub controller featuring four downstream ports. It integrates an 8051 microcontroller for managing complex hub functions and supports advanced features like Battery Charging 1.2 and FlexConnect for port role switching. This controller is designed for high-speed data throughput and robust power management in commercial environments.
Why Choose This Part
The device features ProTouch configuration via SPI or SMBus, allowing for deep customization of port mapping and power delivery. It includes PHYBoost and VariSense technologies to maintain signal integrity over long PCB traces or poor quality cables. With an integrated 8051 core and 64KB of Flash, it offloads complex USB housekeeping tasks from the host processor while maintaining low power consumption.
Applications
Key Specifications
Getting Started
Designers should refer to the EVB-USB5744 evaluation board for circuit reference and layout best practices for 5Gbps differential pairs. Configuration is performed using Microchip's ProTouch2 software tool, which allows engineers to program the internal OTP or external SPI ROM for custom VID/PID and port behavior. Ensure proper 1.2V and 3.3V power sequencing and impedance-controlled routing for all USB high-speed signals.
