USB5534B-5000JZXTR: A 4-Port USB 3.0 Gen 1 Hub Controller from Microchip
The USB5534B-5000JZXTR is a highly integrated, low-power hub controller from Microchip Technology, designed to provide robust and high-performance USB connectivity expansion. As a 4-port USB 3.0 Gen 1 hub controller, it serves as a critical component in modern computing and peripheral ecosystems, enabling the seamless addition of multiple high-speed USB ports to a wide array of host systems.
Engineered for versatility, this hub controller supports SuperSpeed USB (5 Gbps), High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates on each of its four downstream ports. This ensures full backward compatibility with the vast installed base of USB 2.0 and USB 1.1 devices, making it an ideal solution for docking stations, monitors, desktop PCs, and embedded systems where a variety of legacy and modern peripherals must coexist.
A key strength of the USB5534B lies in its advanced system integration and power management features. The controller incorporates a fully integrated 5V to 3.3V and 5V to 1.2V voltage regulator, significantly reducing the need for external components, simplifying PCB design, and lowering the overall bill of materials (BOM) cost. Its sophisticated power management supports individual or ganged power control and switching for each downstream port, along with comprehensive over-current protection. This ensures both safety and efficiency, allowing for the hot-plugging of devices without risking damage to the host or the hub.

Furthermore, the device is designed with a low-power architecture, making it suitable for power-sensitive applications. It supports multiple low-power states, aligning with modern energy efficiency requirements. The USB5534B also features port mapping and custom configuration options through a serial I²C EEPROM interface. This programmability allows OEMs to tailor the hub's behavior—such as disabling specific ports or modifying vendor IDs and product IDs—to meet the precise needs of their end product without altering the hardware design.
Compliance is a critical factor in interface technology, and the USB5534B is engineered to meet USB-IF certification requirements, guaranteeing interoperability and reliability across different devices and hosts. Its robust design ensures stable data transfer, which is paramount for demanding applications like external storage, high-resolution video capture, and high-fidelity audio interfaces.
In summary, the Microchip USB5534B-5000JZXTR stands out as a reliable, flexible, and cost-effective solution for expanding USB 3.0 connectivity. Its high level of integration, superior power management, and configuration flexibility make it a preferred choice for designers aiming to enhance the functionality and user experience of their systems.
