The Microchip USB7216 hub is a low-power, OEM configurable, USB 3.1 Gen 2 hub controller with 6 downstream ports and advanced features for embedded USB applications. The USB7216 is fully compliant with the Universal Serial Bus Revision 3.1 Specification and USB 2.0 Link Power Management Addendum. The USB7216 supports 10 Gbps Super-Speed+ (SS+), 5 Gbps SuperSpeed (SS), 480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-Speed (LS) USB downstream devices on four standard USB 3.1 Gen 2 downstream ports and only legacy speeds (HS/FS/LS) on two standard USB 2.0 downstream ports.
The USB7216 is a standard USB 3.1 Gen 2 hub that supports native basic Type-C with integrated CC logic on downstream port 1. The downstream Type-C port includes an internal USB 3.1 Gen 2 multiplexer; no external multiplexer is required for Type-C support.The USB7216 supports the legacy USB speeds (HS/FS/LS) through a dedicated USB 2.0 hub controller that is the culmination of seven generations of Microchip hub feature controller design and experience with proven reliability, interoperability, and device compatibility. The SuperSpeed hub controller operates in parallel with the USB 2.0 controller, decoupling the 10/5 Gbps SS+/SS data transfers from bottlenecks due to the slower USB 2.0 traffic.
