7.1 Overview

USB Type-C® is a 24-pin connector that allows for transmission of large amounts of power and data on a single cable. USB Type-C® is able to support USB 2.0 and all standards after as well as alternate modes like HDMI and DisplayPort. The standard also supports the USB-PD standard which is primarily implemented on the USB Type-C connector. Figure 7-1 details the pin configuration for the USB Type-C® connector.

While USB Type-C® incorporates the same pins mentioned throughout the application note such as D+ and D- and the TX/RX lines, there are additional pins specific to USB Type-C®: CC1/CC2 and SBU1/SBU2. The CC pins are the channel configuration pins. The pins are able to detect cable attachment, cable orientation, and current advertisement. The SBU pins are for sideband use. The pins are used in audio adapter accessory mode and alternate modes. The alternate modes include DisplayPort, HDMI, and Thunderbolt. The following section means the ESD protection requirements to properly protect a USB Type-C® connector.
