USB Type-C (USB-C for short), which has a new interface size and a slightly cooler name, is very easy to make the first time to hear this term of partners think that this is a new USB standard, but in fact it is not. Type-C is just a part of the USB 3.1 standard, not a new standard.

In fact, the USB 3.1 standard has three types of interfaces, Type-A, Type-B, and Type-C. The specification of Type-C is made in accordance with the USB 3.1 standard, so USB 3.1 can be made into Type-C, Type-A, and other types, but Type-C is not the same as USB 3.1.

For example, nowadays, a lot of For example, many cell phones are now using Type-C interfaces, but many of them are still USB 3.0, or even USB 2.0 interfaces, and there are not many Type-C interfaces that actually use the USB 3.1 standard, which has the biggest reputation of being the Apple's 12-inch New Macbook.

One of the most important things is that the interface definition of the USB type c interface is introduced.

There are a total number of Type-c interfaces. type-c interface has a total of 24 pins, can be inserted forward and reverse and fast transfer speeds, the interface is not directional, so that the user to avoid the use of the wrong plug in the situation. Generally referred to as type c, type-c, etc. These refer to the same product. USB3.0 interface is usually 9 to 11, USB2.0 only 4 pins. The increase in the number of pins does not result in a larger type-c interface, it actually reduces the size (relative to the standard port) to meet the needs of mobile devices.

Two, USB3.1 type-c interface features

Feature 1, the new interface design, the size of about 8.4mm x 2.6mm, the interface is slim

Feature 2, power output capacity: standard cable 3A, interface 5A

Feature 3, can be used to transmit DisplayPort signal, support for 4K UHD image

Feature 4: Provides up to 100% power transfer

Feature 5: Better EMI and RFI mitigation

Feature 7: USB Power Delivery for charging

Feature 8: Maximum power output: 3A for standard cable, 5A for interface

Feature 9: Maximum power output: 3A for standard cable, 5A for interface

Features 8: Up to 4K UHD video transmissions, support for 4K UHD video transmissions

Feature 8, the highest data transfer speed of 10Gbps, based on the USB3.1 specification

Three, the advantages of the USB Type-C interface

Advantages 1, equipped with a Type-C connector standard specification connecting cable, can be passed through the 3A current, but also supports beyond the existing USB power supply capacity of "USBPD", can provide a maximum of 100W of power;

Benefit 2, DisplayPort Alternate Mode, supports resolutions up to 4K Ultra HD (UHD) and even 8K.

Benefit 3, Maximum data transfer speed up to 10Gbps, also USB 3.1 standard, compatible with USB 2.0 standard;

Benefit 4, Supports "Forward and Reverse Plug-In" function which can be plugged in from both the front and back;
