USB5744 4-Port SS/HS USB Controller Smart Hub Microchip USB5744 4-Port SuperSpeed/High-speed USB Controller Smart Hub provides low-power, OEM configurability and advanced features for embedded USB applications. All enabled downstream ports are supported through 5Gbps SuperSpeed (SS), 480Mbps Hi-Speed (HS), 12Mbps Full-Speed (FS), and 1.5Mbps Low-Speed (LS) USB downstream devices. Legacy USB speeds (HS/FS/LS) are supported through a dedicated USB 2.0 hub feature controller, with the proven reliability, interoperability, and device compatibility of five generations of Microchip hub feature controller design. Operating in parallel with the USB 2.0 controller, the SuperSpeed hub feature controller disunites the 5Gbps SuperSpeed data transfers from blockage due to the slower USB 2.0 transfers.
