7 Detailed Description
7.1 Overview
The USB Type-C ecosystem operates around a small form factor connector and cable that is flippable and
reversible. Because of the nature of the connector, a scheme is needed to determine the connector orientation.
Additional schemes are needed to determine when a USB port is attached and the acting role of the USB port
(DFP, UFP, DRP), as well as to communicate Type-C current capabilities. These schemes are implemented over
the CC pins according to the USB Type-C specifications. The TUSB320 device provides Configuration Channel
(CC) logic for determining USB port attach and detach, role detection, cable orientation, and Type-C current
mode. The TUSB320 device also contains several features such as mode configuration and low standby current
which make this device ideal for source or sinks in USB2.0 applications.
