Overview

The USB4604I-1080HN is an industrial-grade, 4-port USB 2.0 Hi-Speed hub controller that supports High-Speed Inter-Chip (HSIC) connectivity. It features a versatile Upstream port that can interface via standard USB or HSIC, and it includes integrated FlexConnect technology for port swapping and switching. This controller is designed for embedded systems requiring robust USB expansion in a compact 7x7mm SQFN package.

Why Choose This Part

This controller offers an industrial operating temperature range from -40C to 85C and includes 256KB of RAM for firmware execution. Its support for HSIC reduces power consumption and PCB trace complexity compared to standard USB physical layers, while the integrated I2C/SPI interfaces allow for flexible system configuration and monitoring.

Applications

Industrial Embedded PC Expansion
Provides four downstream USB 2.0 ports for connecting peripherals to industrial motherboards or SBCs in harsh environments.
Automotive Infotainment Systems
Utilizes HSIC for low-power, chip-to-chip connectivity between the application processor and the hub controller.
USB Port Replicators
Leverages FlexConnect to dynamically switch hub upstream and downstream roles in docking station designs.
Medical Instrumentation
Integrates into medical devices to manage multiple internal and external USB sensors and interface modules.

Getting Started

Designers should refer to the Microchip USB4604 SDK and evaluation boards for rapid prototyping. Configuration can be performed via external I2C/SMBus master or by loading custom firmware into the device's RAM; ensure the 1.8V and 3.3V supply rails meet the noise specifications defined in the datasheet.
