USB 3.1 SmartHub offers Type-C support, 5Gbps data rates in cars
Microchip’s automotive-qualified USB 3.1 Gen1 SmartHub IC offers up to 10 times faster data rates over existing USB 2.0 solutions, reducing indexing times to improve the user experience in vehicles.

To support the rising adoption of USB Type-C in the smartphone market and enable universal connectivity in vehicles, the USB7002 SmartHub IC includes interfaces for USB Type-C connectors. The 5 Gbps SuperSpeed data rates of USB 3.1 ensure higher bandwidth and maximum functionality, making it well suited for applications that require gigabit speeds for faster data streaming, data download and in-vehicle communication. The USB7002 also reduces the download time for large videos, which is ideal for vehicles that have integrated 4K dash cams. The USB7002 enables direct USB Type-C connections through native Configuration Channel (CC) pin interfaces and integrated 2:1 multiplexers that support the reversible connection feature of the USB Type-C connector. The SmartHub ICs feature patented multi-host end-point reflector technology, which enables USB data to be mirrored between two USB hosts.

This enables the graphical user interface of a phone to be displayed on the vehicle’s screen and integrate with voice commands inside the car, while simultaneously charging the mobile device. The USB7002-I/KDXVA0 is AEC-Q100 Grade 3 qualified and available now in volume production quantities.
