USB4604I-1080HN: Microchip's 4-Port USB 2.0 Hi-Speed Hub Controller

In the realm of connectivity, the demand for efficient and reliable USB hub solutions remains consistently high. Addressing this need, Microchip Technology introduces the USB4604I-1080HN, a robust 4-Port USB 2.0 Hi-Speed Hub Controller designed to deliver superior performance and flexibility for a wide range of applications. This highly integrated controller is engineered to meet the rigorous requirements of modern computing, industrial, and embedded systems, providing a seamless expansion solution for USB peripherals.

At the heart of the USB4604I-1080HN is its advanced system-on-chip (SoC) architecture, which consolidates a USB 2.0 hub controller, a microprocessor, and all necessary termination resistors into a single, compact package. This integration significantly reduces both the bill of materials (BOM) and the physical footprint on the PCB, making it an ideal choice for space-constrained designs. The hub supports Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates, ensuring full backward compatibility with legacy USB devices.

One of the standout features of this controller is its robust power management capabilities. It supports individual or ganged power switching and port power control, allowing for efficient management of connected devices. Each downstream port can be configured to provide up to 500mA of current, adhering to the USB 2.0 specification. Furthermore, the device includes comprehensive over-current detection and protection mechanisms, enhancing system reliability and safeguarding against potential faults.

The USB4604I-1080HN also excels in terms of signal integrity and EMI performance. It incorporates advanced features such as spread spectrum technology and integrated phase-locked loops (PLLs) to minimize electromagnetic interference (EMI), which is critical for passing stringent regulatory certifications. The controller's design ensures stable and error-free data transmission across all ports, even in electrically noisy environments.

For developers, Microchip provides extensive support through evaluation boards and software tools, simplifying the integration and testing process. The hub controller can be configured via external EEPROM or through its SMBus interface, offering flexibility in customizing various parameters, including vendor ID, product ID, and port behaviors.

In summary, the USB4604I-1080HN represents a highly reliable and feature-rich solution for expanding USB connectivity in diverse electronic systems. Its combination of performance, integration, and power efficiency makes it a preferred choice for designers seeking to enhance their product's capabilities without compromising on quality or reliability.
