Microchip Technology's USB4640I-HZH-03: High-Speed USB 2.0 Hub and HSIC USB 2.0 Hub with Multi-TRAK
The USB4640I-HZH-03 is a cutting-edge connectivity solution from Microchip Technology, designed to enhance the performance and flexibility of USB 2.0 applications. This high-speed USB hub controller integrates a 2-port USB 2.0 hub with a USB 2.0 High-Speed Inter-Chip (HSIC) interface, making it an ideal choice for a wide range of applications in computing, docking stations, monitors, and other embedded systems.
One of the key features of the USB4640I-HZH-03 is its support for Multi-TRAK technology, which allows the device to provide a separate transaction translator for each downstream port. This ensures maximum bandwidth for connected devices, as each port is capable of operating at full high-speed data transfer rates independently of the others. This is particularly beneficial in mixed-speed USB environments where both high-speed and full-speed/low-speed devices are in use.
The hub controller is also equipped with a HSIC interface which offers a significant reduction in power consumption and pin count compared to traditional USB 2.0. The HSIC connection is a two-wire interface that operates at 480 Mbps and provides a direct link to the host processor, thus reducing overall system complexity and cost.
Designed with robustness in mind, the USB4640I-HZH-03 features built-in ESD protection circuits to safeguard against electrostatic discharges, ensuring the reliability and longevity of the product in various environments. Furthermore, the device is compliant with the USB 2.0 specification and is backward compatible with USB 1.1, ensuring seamless integration with existing USB peripherals and systems.
For developers, Microchip Technology provides extensive technical support, including reference designs and software drivers, to facilitate the implementation of the USB4640I-HZH-03 into any USB 2.0 application. The hub controller is available in a compact 36-pin QFN package, making it suitable for space-constrained applications while providing ample functionality for a multitude of USB connectivity needs.
Overall, the USB4640I-HZH-03 from Microchip Technology is a versatile and high-performance solution that meets the increasing demands for efficient and reliable USB connectivity in modern electronic devices.
