![]() Furthermore, dual-role devices that implement USB Power Delivery may independently and dynamically swap data and power roles using the Data Role Swap or Power Role Swap processes. When two such devices are connected, the roles are randomly assigned but a swap can be commanded from either end, although there are optional path and role detection methods that would allow devices to select a preference for a specific role. These types of ports are called Dual-Role-Data (DRD) ports, which was known as USB On-The-Go in the previous specification. Some, such as mobile phones, can take either role depending on what kind is detected on the other end. Devices ĭevices may be hosts (with a downstream-facing port, DFP) or peripherals (with an upstream-facing port, UFP). There are USB-IF certification programs available for USB-C products and end users are recommended to use USB-IF certified cables. There are also cables which can carry only USB 2.0 with up to 480 Mbit/s data rate. They are marked with a SuperSpeed+ (SuperSpeed 10 Gbit/s) logo. įull-featured USB-C cables that implement USB 3.1 Gen 2 can handle up to 10 Gbit/s data rate at full duplex. USB Charging ports should also be clearly marked with capable power wattage. USB-C to USB-C cables supporting 5A current must contain e-marker chips (also marketed as E-Mark chips) programmed to identify the cable and its current capabilities. These USB-C cables only support 2.0 speeds and do not support alternate modes.Īll USB-C cables must be able to carry a minimum of 3 A current (at 20 V, 60 W) but some can also carry high-power 5 A current (at 20 V, 100 W). USB-C cables that do not have shielded SuperSpeed pairs, sideband use pins, or additional wires for power lines can have increased cable length, up to 4 m. The electronic ID chip provides information about product/vendor, cable connectors, USB signalling protocol (2.0, Gen 1, Gen 2), passive/active construction, use of V CONN power, available V BUS current, latency, RX/TX directionality, SOP controller mode, and hardware/firmware version. Cable length should be ≤2 m for Gen 1 or ≤1 m for Gen 2. They are electronically marked cables that contain a chip with an ID function based on the configuration channel and vendor-defined messages (VDM) from the USB Power Delivery 2.0 specification. USB 3.1 cables are considered full-featured USB-C cables. Receptacles are found on devices and adapters. Two genders (kinds) of connectors exist, male (plug) and female (receptacle). The 24-pin double-sided connector is slightly larger than the micro-B connector, with a USB-C port measuring 8.4 millimetres (0.33 in) wide, 2.6 millimetres (0.10 in) high, and 6.65 millimetres (0.262 in) deep. USB-C port (receptacle) on a mobile phone USB Type-C and USB-C are trademarks of USB Implementers Forum. USB-C cables interconnect hosts and devices, replacing various other electrical cables and connectors, including USB-A and USB-B, HDMI, DisplayPort, and 3.5mm audio jacks. 5.2.3 Compatibility with other fast charging technology.5.2.2 Compatibility with audio adapters.3 USB-C receptacle pin usage in different modes. ![]() 2.3 Alternate Mode partner specifications.2.1 USB Type-C Cable and Connector Specification.USB4, released in 2019, is the first USB transfer protocol standard that is only available via USB-C. It preserves existing USB 3.1 SuperSpeed and SuperSpeed+ data modes and introduces two new SuperSpeed+ transfer modes over the USB-C connector using two-lane operation, with data rates of 10 and 20 Gbit/s (1 and ~2.4 GB/s). USB 3.2, released in September 2017, replaces the USB 3.1 standard. Ī device with a Type-C connector does not necessarily implement USB, USB Power Delivery, or any Alternate Mode: the Type-C connector is common to several technologies while mandating only a few of them. In July 2016, it was adopted by the IEC as "IEC 6". It was developed at roughly the same time as the USB 3.1 specification. The USB Type-C Specification 1.0 was published by the USB Implementers Forum (USB-IF) and was finalized in August 2014. The designation C refers only to the connector's physical configuration or form factor and should not be confused with the connector's specific capabilities, which are designated by its transfer specifications (such as USB 3.2). Important: SiliconMotion software must be installed for both HDMI ports to function (see manual for full instructions).USB-C (formally known as USB Type-C) is a 24-pin USB connector system with a rotationally symmetrical connector.
