The Microchip USB2514B-AEZC-TR: A Compact Powerhouse for USB Hub Integration

In the realm of modern connectivity, the need for expanding USB port availability remains critical. The Microchip USB2514B-AEZC-TR stands out as a highly integrated, 4-port USB 2.0 Hi-Speed hub controller designed to provide a robust and flexible solution for a wide array of computing and embedded applications. This system-level chip (SLC) simplifies design while delivering the performance and reliability expected from a industry leader.

Engineered for versatility, this hub controller supports both low-speed (1.5 Mbps), full-speed (12 Mbps), and hi-speed (480 Mbps) data rates on all four downstream ports. Its internal architecture features a multi-transaction translator (MultiTTA) which allows concurrent transactions across all ports. This is a significant advantage, as it maximizes bandwidth and minimizes latency, ensuring that multiple high-speed devices can operate simultaneously without performance bottlenecks.

A key feature of the USB2514B is its fully-integrated design. The controller incorporates all necessary termination resistors, meaning fewer external components are required on the PCB. This not only reduces the overall bill of materials (BOM) and board space but also accelerates time-to-market for product developers. The hub supports a variety of operational modes, including battery charging downstream port (BCD) support, enabling faster charging of portable devices.

The device is offered in a compact, space-saving 36-pin QFN package, making it an ideal choice for space-constrained applications such as ultra-slim notebooks, monitors, docking stations, and embedded systems. Its industrial-grade temperature range ensures reliable operation in demanding environments.
