As the latest interface standards, the computer and consumer electronics market has attracted a lot of attention. Combining features with satisfactory consumers, USB Type-C is expected to become one of the most popular interfaces, but it may also be the most troublesome interface for people. These terms define how the USB Type-C interface supports various non-USB functions.

powered by
The default 5V power of the USB Type-C interface is compatible with the previous USB interface. Not only that, the new USB Type-C interface includes four pins specifically for power and ground. The "USB Power Delivery Specification" allows the USB Type-C interface to support up to 20V and 5A.

Symmetrical connection
The USB Type-C interface is symmetrical, so its insertion and unplugging power and cable directions are both positive and negative. The liberation of the plug -in direction solves the main troubles brought by the previous interface. The type of the previous interface indicates the function of the additional device (the ASTE-A interface is used for the host, and the Type-B interface is used for external devices). The USB Type-C interface can access the end, and the function is defined by hardware to be accessed. The connectors at both ends of the USB Type-C cable are the same, so the plugs and plugs of the cable simplify the cable.

Channel configuration
The USB Type-C interface contains two channel configuration (channel configuration) signal pins (CC1 and CC2) for functional protocols. The above signal determines the direction of the inserting interface and is used to negotiate the power on the interface to replace and the peripheral mode.

Non -USB signal transmission

The USB Type-C interface supports the custom mode of various OEM products to expand the device function. The pins in the yellow mark part can be re-configured using the complete USB Type-C cable. Not only that, you can also reconfigure the pins in the orange label part to directly connect the application.
