USB2642T-I/ML: Microchip's Advanced USB 2.0 Hi-Speed Hub Controller for Embedded Systems

In the rapidly evolving landscape of embedded systems, the demand for robust and high-performance connectivity solutions is paramount. Addressing this need, Microchip Technology introduces the USB2642T-I/ML, a highly integrated USB 2.0 Hi-Speed Hub Controller designed to deliver superior performance and flexibility for a wide range of embedded applications. This controller stands out as a critical component for developers seeking to implement reliable USB expansion in space-constrained and power-sensitive environments.

The USB2642T-I/ML is a 7-port hub controller that supports Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) USB operations, ensuring compatibility with a vast array of USB peripherals. Its advanced architecture incorporates a 32-bit RISC processor and integrated serial EEPROM, enabling efficient data handling and customizable configuration without external memory. This integration significantly reduces the bill of materials (BOM) and simplifies PCB layout, making it an ideal choice for compact designs.

One of the key features of this hub controller is its low power consumption, which is crucial for battery-powered and energy-efficient devices. It supports multiple power management modes, including suspend and resume operations, allowing systems to conserve energy without compromising functionality. Additionally, the device offers individual port power control and over-current detection for each downstream port, enhancing system safety and reliability by preventing damage from faulty peripherals.

The USB2642T-I/ML also excels in providing enhanced EMI performance and signal integrity, thanks to its built-in termination resistors and robust electrical design. This ensures stable operation even in electrically noisy environments, which is common in industrial and automotive applications. The controller’s industrial temperature range (-40°C to +85°C) further underscores its suitability for harsh operating conditions, extending its use beyond consumer electronics to medical, industrial, and automotive markets.

For developers, Microchip offers comprehensive support through pre-certified USB-IF compliance, reducing time-to-market and certification costs. The hub is fully compliant with USB 2.0 specifications and supports various downstream facing port configurations, including compound devices. Its small 28-pin MLF® package (5mm x 5mm) is optimized for space-constrained applications, providing maximum functionality in a minimal footprint.

ICGOOFind: The USB2642T-I/ML from Microchip represents a powerful and versatile solution for embedded USB hub requirements, combining high-speed performance, low power consumption, and robust integration.
