Microchip Technology's USB4604I-1080HN: A High-Performance USB 2.0 Hub Controller

The USB4604I-1080HN from Microchip Technology is a versatile and efficient USB 2.0 hub controller that is designed to cater to the needs of high-speed data transfer and connectivity solutions. This advanced hub controller is an ideal choice for a wide range of applications, including desktop and laptop computers, docking stations, monitors, and other peripherals requiring multiple USB ports.

Boasting a high-performance interface, the USB4604I-1080HN supports multi-TT (Transaction Translator) operation, which ensures seamless and efficient management of bandwidth for full-speed and low-speed devices connected to a high-speed hub. This feature is particularly important for maintaining optimal data transfer rates and reducing bottlenecks when multiple devices are in use.

The device comes with an integrated 2C master, which allows for easy attachment of serial EEPROMs, thermal sensors, or other I²C devices without the need for additional components. This integration simplifies design and reduces the overall bill of materials for system developers.

The USB4604I-1080HN is also equipped with PortMap and PortSwap features. PortMap allows for the logical port mapping of the physical ports, which can be very useful for system layout and design. PortSwap is a pin-strapping option that offers the ability to swap the differential D+ and D- signals at the USB connector, ensuring flexibility in PCB routing and simplifying the design process.

For added convenience, the USB4604I-1080HN is available in a 64-pin QFN (Quad Flat No-lead) package, providing a compact footprint for space-constrained applications. Its industrial temperature range of -40°C to 85°C ensures reliable performance across various environments and applications.

In summary, the USB4604I-1080HN hub controller from Microchip Technology is a robust and feature-rich solution that offers enhanced connectivity options for developers looking to incorporate multiple USB interfaces into their products. With its advanced features and compact design, it stands out as a high-quality component for any USB 2.0 application.
