The Microchip USB2513BI-AEZG-TR: A Compact Powerhouse for USB Hub Integration

In the realm of modern connectivity, the demand for efficient and reliable USB expansion continues to grow. The Microchip USB2513BI-AEZG-TR stands out as a premier solution, a highly integrated 3-port USB 2.0 Hi-Speed hub controller designed to simplify design and enhance performance in a vast array of applications. This system-on-chip (SoC) controller is engineered to provide a seamless and robust connectivity experience, making it an ideal choice for embedded systems, desktop peripherals, docking stations, and industrial equipment.

A key strength of the USB2513BI lies in its high level of integration. The controller incorporates all the essential logic and analog circuitry needed for a fully compliant USB hub, including USB transceivers, a 5V-to-3.3V voltage regulator, and series termination resistors. This significantly reduces the bill of materials (BOM) and simplifies PCB layout, allowing for a more compact and cost-effective design. Designers can achieve a fully functional 3-port hub with minimal external components, accelerating time-to-market.

Performance is paramount, and this hub controller delivers. It fully complies with the USB 2.0 specification, supporting Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates. Each downstream port features individual port power control and over-current detection, enabling sophisticated power management. This allows the host system to monitor power consumption on a per-port basis and safely manage connected devices, including those that are bus-powered.

Furthermore, the device offers crucial flexibility through a series of configurable EEPROM-less settings. Using external pin strapping, designers can tailor the hub's behavior without needing external memory. Key parameters such as vendor ID, product ID, port disable functions, and LED mode indicators can be easily configured to meet specific application requirements. For even greater customization, the hub can be interfaced with an external serial EEPROM to load a complete custom configuration descriptor.

Packaged in a space-saving 36-pin QFN format, the USB2513BI-AEZG-TR is built for durability and performance in commercial applications, operating within a standard temperature range of 0°C to +70°C. Its robust design ensures stable data transfer across its three downstream ports, making it a reliable cornerstone for any system requiring expanded USB connectivity.

ICGOODFIND: The Microchip USB2513BI-AEZG-TR is a superior highly integrated 3-port USB 2.0 hub controller that excels in reducing design complexity and component count. Its robust feature set, including individual power switching and flexible configuration options, makes it an exceptional choice for developers seeking a reliable, efficient, and compact connectivity solution for a wide range of electronic products.
