The Microchip USB7002 [SmartHub](https://www.microchip.com/en-us/products/interface-and-connectivity/usb/usb-hubs/smarthub-ics)™ IC is a low-power, OEM configurable, USB3.2 Gen 1 hub controller with 4 downstream ports and advanced features for embedded USB applications. The USB7002 is fully compliant with the Universal Serial Bus Revision 3.2 Specification and USB2.0 Link Power Management Addendum. The USB7002 supports 5 Gbps Super-Speed (SS), 480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-Speed (LS) USB downstream devices on all enabled downstream ports.

A SmartHub IC is defined as a USB hub that integrates system levels functions typically associated with a separate MCU or processor. The USB7002 SmartHub IC enables communication to other peripherals in addition to USB. This I/O Bridging capability allows the host to seamlessly interface to peripherals via I²C, SPI or GPIOs over USB. The USB7002 also enable a downstream device to take control of the host system by swapping roles and becoming the host port. The USB7002 can also switch between two different hosts if required. This role changing technology is called FlexConnect and can be initiated through hardware or software commands.

The USB7002 supports native Type-C connectivity on the upstream port and two of the downstream ports. The hub includes internal Type-C CC pin logic and an internal USB3.2 Gen 1 multiplexer to support both Type-C insertion orientations. The USB7002 also supports the legacy USB speeds (HS/FS/LS) through a dedicated USB2.0 hub controller that is the culmination of six 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 USB2.0 controller, decoupling the 5 Gbps SS data transfers from bottlenecks due to the slower USB2.0 traffic.Read more
