USB3.1 can you let the interface unify?

From the advent of the PC to date, the development of the interface has evolved, some with the advance of time has disappeared, and USB is undoubtedly one of the most enduring interface, from the 1996 USB1.0, has been nearly 20 years of history, and the interface rate from USB1.0 development to USB3.1.

Each version of the innovation brings a faster rate of transmission. USB Transmission Speed from 1.0 (1.5Mbps), 2.0 (480Mbps), 3.0 (5Gbps), developed to today's maximum transmission speed 10Gbps. And in the speed of innovation at the same time, each generation of USB interface type is also evolving, today we will talk about the development of USB interface type.

The reason why today I want to talk to you about USB interface, the main reason is of course the current very hot USB3.1 type-c interface, and its hot because of the world's attention to the new Apple launch, its latest release of the MacBook Port has been changed, The entire machine does not have any other interface, only with a USB3.1 type-c interface, it is precisely because of this, this interface is the attention of people, but many consumers do not know it, or even mistakenly think that the USB3.1 type-c interface is Apple's invention, Even think it and Apple Lightning line is the same product, because they look very similar, and the same characteristics are can be arbitrarily inserted.

To get a better understanding of this interface, let's first look at the USB interfaces we've seen over the years, which is the most common of us, and before the USB2.0 era, there were a number of USB ports:

　　Before the USB2.0 era (max speed 480Mbps):

(left) is the most common type a USB port (right) for B-Type USB interface

Left Mini USB Type A (right) Mini USB B

　　In fact, it is easy to remember these few interfaces:

-Type A: General for PCs

-Type B: Generally used for 3.5-inch mobile hard disk, as well as printers, monitors and other connections

-Mini-usb: For mobile devices such as digital cameras, digital cameras, measuring instruments and mobile hard drives

　　USB 2.0 Standard Portable version-micro USB port appears

In the USB2.0 era, the Micro USB port appeared, a portable version of the USB 2.0 standard, the next-generation specification for mini USB, smaller than the mini USB interface used by earlier parts of the phone.

▲micro USB Interface: This interface is believed to be very familiar, because most Android phones are now used in this connection.

USB3.0 era-A new type of Micro USB 3.0 B-Interface (max speed 5Gbps):

▲micro USB3.0 B-type interface: For USB3.0 mobile hard disk and other USB3.0 devices.

Today-the newest USB3.1 type-c interface appears (Max 10Gbps):

2013 USB3.1 was born, responsible for the development of USB standards for the organization of USB Promoter Group, this organization is also the designer of the USB Type-c interface, USB3.1 has three kinds of connection interface, Type-a (standard-a), Type-b ( Micro-b) and Type-c

Type-a is also the most widely used USB A-type interface for computer connection; The type-b is the Micro B-interface above, mainly used for devices such as smartphones and tablets, while type-c is focused on lighter, thinner devices (the future may be to unify the interface of mobile phones and replace the Micro USB interface).

　　TYPE-C PIN Definition

Each of the USB upgrades are faced with the same problem, that is the major parts manufacturers of recognition and cooperation, in the USB3.0 era, major motherboard manufacturers to produce the main board interface is still USB2.0 interface, after all, the USB2.0 scheme is more stable. The reason is many, but the most important factor is still subject to the platform before the replacement of the lag and third-party bridging chip costs too much, but with 2012 Intel in the newly launched Ivy Bridge platform to achieve the original USB3.0, just direct people into the USB3.0 era of popularization, with the introduction of high-end motherboards to join the USB3.0 interface. and PC peripherals manufacturers are also very rapid action, Kingston, Western data and other well-known brands have launched the use of USB3.0 interface of mobile storage products.

Today, to achieve the development of USB3.1, but also the motherboard and other hardware support, but some retailers have begun to sell, such as Asus in the year after the release of 14 USB 3.1 motherboard, MSI, Ying-Tai and other manufacturers are also follow up. And the Apple notebook will also greatly promote its development, but compared to the upgrade, mobile phones and tablets may be faster to promote the development of USB 3.1 progress.

▲ This picture can be more obvious to see the difference between the USB3.1 Type-c interface and the Apple Lightning Line

USB3.1 Type-c interface will play a very important role in mobile devices, from the current point of view, the type-c of USB3.1 is most likely to become the future connectivity standards, providing data transmission, peripheral connectivity, display output, such as integrated connectivity scheme.

It is reported that the EU 2017 will force all mobile devices to unify the USB3.1 interface. USB3.1 In addition to the computer field, mobile phones, tablets will be in full swing next year, and the technology is also supported by Intel, Google, Microsoft and Apple.

The new MacBook lets people know the USB Type-c interface, also lets everybody see the future development trend of the equipment, in the next days, USB3.1 type-c equipment will continue to appear. The USB Type-c interface will undoubtedly become popular over the next few years, eventually replacing USB3.0 as USB3.0 replaces USB2.0. And on the phone, flat-panel mobile devices, it has several characteristics that can enable faster charging of mobile phones, with higher data transmission speed, support display output, more suitable as a mobile device output interface, the most important, at present very much need a universal universal interface to enhance the connectivity between the various devices. And these characteristics can let USB3.1 type-c really become the future unified interface, let us try to stay.
