IEC 62680-1-3:2022 defines the USB Type-C\u00ae receptacles, plug and cables. The USB Type-C Cable and Connector Specification is guided by the following principles: – Enable new and exciting host and device form-factors where size, industrial design and style are important parameters – Work seamlessly with existing USB host and device silicon solutions – Enhance ease of use for connecting USB devices with a focus on minimizing user confusion for plug and cable orientation The USB Type-C Cable and Connector Specification defines a new receptacle, plug, cable and detection mechanisms that are compatible with existing USB interface electrical and functional specifications. This specification covers the following aspects that are needed to produce and use this new USB cable\/connector solution in newer platforms and devices, and that interoperate with existing platforms and devices: – USB Type-C receptacles, including electro-mechanical definition and performance requirements – USB Type-C plugs and cable assemblies, including electro-mechanical definition and performance requirements – USB Type-C to legacy cable assemblies and adapters – USB Type-C-based device detection and interface configuration, including support for legacy connections – USB Power Delivery optimized for the USB Type-C connector The USB Type-C Cable and Connector Specification defines a standardized mechanism that supports Alternate Modes, such as repurposing the connector for docking-specific applications. IEC 62680-1-3:2022 cancels and replaces the fourth edition published in 2021 and constitutes a technical revision. This standard is the USB-IF publication Universal Serial Bus Type-C Cable and Connector Specification Revision 2.0. New release primarily for enabling Extended Power Range (EPR) and defining EPR cables aligning with USB Power Delivery Specification R3.1 V1.0. Also includes incorporation of all approved ECNs as the revision date plus editorial clean-up.<\/p>\n
