The Microchip USB7052N [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 USB7052N is fully compliant with the Universal Serial Bus Revision 3.2 Specification and USB2.0 Link Power Management Addendum. The USB7052N 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 USB7052N 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 USB7052N also enable a downstream device to take control of the host system by swapping roles and becoming the host port. The USB7052N 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 USB7052N supports native Type-C connectivity on two of the downstream ports. The hub includes internal Type-C CC pin logic and an internal USB 3.2 Gen 1 multiplexer to support both Type-C insertion orientations. The USB7052N supports an additional 2 x Type A ports downstream - 1 x USB3.2 Gen1 and 1 x USB2.0. The hub also supports 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 USB 2.0 traffic.Read more
