USB-C, often known as USB Type-C, is a 24-pin USB connector featuring a symmetrical rotatable connector.
The USB Implementers Forum (USB-IF) issued and finalized the USB Type-C Specification 1.0 in August 2014. It was created at around the same time as the USB 3.1 standard. The International Electrotechnical Commission (IEC) accepted it as “IEC 62680-1-3” in July 2016.
A device with a Type-C connector may or may not support USB, USB Power Delivery, or any Alternate Mode: the Type-C connector is shared by numerous technologies while only mandating a handful of them.
The USB 3.2 standard, which was published in September 2017, is the successor to the USB 3.1 standard. It keeps existing USB 3.1 SuperSpeed and SuperSpeed+ data modes and adds two additional SuperSpeed+ transfer modes employing two-lane operation via the USB-C connector, with data rates of 10 and 20 Gbit/s (1 and 2.4 GB/s), respectively.
USB4, which was announced in 2019, is the first USB transfer protocol standard to be available exclusively through USB-C.
Overview
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.
Connectors
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, the 24-pin double-sided connector is slightly larger than the micro-B connector. Male (plug) and female (socket) connectors are the two genders (types) of connectors (receptacle).
Cables
USB-C cables with USB 3.1 support are considered full-featured USB-C cables. They are electronically identified cables with an ID function based on the USB Power Delivery 2.0 specification’s configuration channel and vendor-defined messages (VDM). The cable length for Gen 1 should be 2 m, and for Gen 2 it should be 1 m. Product/vendor information, cable connectors, USB signaling protocol (2.0, Gen 1, Gen 2), passive/active construction, use of VCONN power, available VBUS current, latency, RX/TX directionality, SOP controller mode, and hardware/firmware version are all provided via the electronic ID chip.
Cable lengths of up to 4 meters are possible with USB-C cables that do not feature shielded SuperSpeed pairs, sideband usage pins, or additional wires for power lines. These USB-C cables can only transfer data at 2.0 Mbps and do not support any other modes.
All USB-C cables must be able to carry a minimum of 3 A current (at 20 V, 60 W), however high-power 5 A current is also possible (at 20 V, 100 W). E-marker chips (also known as E-Mark chips) are required in USB-C to USB-C cables that carry 5A current. These chips are configured to identify the cable and its current capability. USB charging ports should also be clearly labeled with the maximum power wattage they can handle.
Devices
Devices can be hosts (with a downstream-facing port, DFP) or peripherals (with a downstream-facing port, DFP) (with an upstream-facing port, UFP). Mobile phones, for example, can play either duty depending on the type of signal received on the other end. Dual-Role-Data (DRD) ports, which were previously known as USB On-The-Go, are the sort of ports in question.
When two similar devices are linked, the roles are allocated at random, but a swap can be requested from either end, and there are optional path and role detection methods that allow devices to specify a preference for a specific role.
Additionally, dual-role devices that support USB Power Delivery can shift data and power responsibilities separately and dynamically using the Data Role Swap and Power Role Swap processes. This enables charge-through hub or docking station applications in which the USB-C device serves as a USB data host while also serving as a power consumer.
In addition to baseline bus power, USB-C devices can optionally provide or consume bus power currents of 1.5 A and 3.0 A (at 5 V); power sources can advertise increased USB current through the configuration channel, or they can implement the full USB Power Delivery specification using both the BMC-coded configuration line and the legacy BFSK-coded VBUS line.
