Can USB 3.1 unify the interface? Talking about the development of USB

   Since the appearance of the PC, the development of interfaces has continued to evolve, and some of them have disappeared over time. Among them, USB is undoubtedly one of the most enduring interfaces. It has been nearly 20 years since the appearance of USB1.0 in 1996. History, and the interface rate has also developed from USB1.0 to USB3.1.

　　 Each version of the innovation has brought a higher transmission rate. The USB transmission speed has evolved from 1.0 (1.5Mbps), 2.0 (480Mbps), and 3.0 (5Gbps) to today's maximum transmission speed of 10Gbps. At the same time of speed innovation, each generation of USB interface types has also evolved and developed, and today we will talk about the development of USB interface types.

  The reason why I want to talk to you about the USB interface today is, of course, the emergence of the very popular USB3.1 TYPE-C interface, and the reason for its popularity is due to the latest release of Apple’s new product launch conference that has attracted worldwide attention. The port of MacBook has been changed. The whole machine does not have any other interfaces, only a USB3.1 Type-C interface. It is precisely because of this that this interface has attracted attention, but many consumers still don’t know it well. I even mistakenly believe that the USB3.1 Type-C interface is Apple’s invention, and even believe that it is the same product as Apple’s Lightning cable, because they are very similar in length, and the same feature is that they can be free of charge regardless of the pros and cons. Plug in.

   In order to let everyone know this interface more clearly, let us first review the USB interfaces we have seen over the years. This is the most common one for us. Before the USB2.0 era, there were many types of USB ports:

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

 -Type A: Generally used for PC

-Type B: Generally used for 3.5-inch mobile hard drives, printers, monitors, etc.

-Mini-USB: generally used for mobile devices such as digital cameras, digital video cameras, measuring instruments, and mobile hard drives.

 Portable version of USB 2.0 standard-Micro USB port appeared

    In the USB2.0 era, the Micro USB port appeared. This is a portable version of the USB 2.0 standard. The next-generation Mini USB specification is smaller than the Mini USB port used in some early mobile phones.

 -Micro USB interface: I believe everyone is very familiar with this interface, because most Android phones currently use this interface.

USB3.0 era-the emergence of a new Micro USB 3.0 Type B interface (speed up to 5Gbps):

 In the USB3.0 era, a new type of Micro USB 3.0 Type B interface appeared

 -Micro USB3.0 Type B interface: used on USB3.0 devices such as USB3.0 mobile hard drives.

Now-the latest USB3.1 Type-C interface appears (speed up to 10Gbps):

   USB3.1 was born in 2013. The organization responsible for formulating the USB standard is the USB Promoter Group. This organization is also the designer of the USB Type-C interface. USB3.1 has three connection interfaces, namely Type-A (Standard-A) , Type-B (Micro-B) and Type-C

 Type-A is also the most widely used USB type A interface for computer connection; Type-B is the above Micro B type interface, which is mainly used in devices such as smartphones and tablet computers; and Type-C is mainly for thinner and lighter , Slenderer equipment (in the future, it may unify the interface of mobile phones and tablets, replacing the Micro USB interface).

 Type-C pin definition

   Every USB upgrade faces the same problem, which is the recognition and cooperation of major accessory manufacturers. In the USB3.0 era, most of the motherboard interfaces produced by major motherboard manufacturers are still USB2.0 interfaces. After all, USB2.0’s The scheme is more stable. There are many reasons for this, but the most important factor is still subject to the manufacturer’s lag in integration before platform replacement and the high cost of third-party bridge chips. However, with Intel’s implementation of native USB3 in the newly launched Ivy Bridge platform in 2012 .0, directly leading people into the era of USB3.0 popularization, with the continuous introduction of high-end motherboards to add USB3.0 interface. And PC peripheral manufacturers are also very fast, and well-known brands such as Kingston and Western Digital have also launched mobile storage products that use USB3.0 interfaces.

Nowadays, if you want to achieve the development of USB3.1, you need the full support of motherboards and other hardware. However, some retailers have already begun to sell them. For example, ASUS has released 14 USB 3.1 motherboards after the year, and manufacturers such as MSI and Biostar are also following up. . The power of Apple's notebook will also greatly promote its development, but in comparison, this upgrade, mobile phones and tablets may be able to promote the progress of USB 3.1 development faster.

The emergence of USB3.1 Type-C interface will play a very important role for mobile devices. From the current point of view, Type-C in USB3.1 is most likely to become the future connection standard, providing data transmission and peripheral connection , Display output and other integrated connection schemes.

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

   The new MacBook let people know the USB Type-C interface, and also let everyone see the development trend of future devices. In the coming days, USB3.1 Type-C devices will continue to appear. The USB Type-C interface will undoubtedly become popular in the next few years, and eventually replace USB3.0 as USB3.0 replaces USB2.0. Moreover, on mobile devices such as mobile phones and tablets, it has several features that can make mobile phones charge faster, have higher data transmission speeds, support display output, and are more suitable as the output interface of mobile devices. A universal interface is needed to improve the connectivity between devices. And whether these features can make USB3.1 Type-C truly a unified interface in the future, let's try it out.
