   USB interface is widely used because it supports hot plugging function, easy to carry, standard and unified, and can be used by multiple devices. Our common U disk, keyboard, mouse, charger and other 127 peripherals are all USB. Interface, it can be seen that the USB interface has a prominent position in the global electronics industry, and USB development has undergone various changes so far. The interface is small, but the learning is not small. Today, let Xiaoxue take a brief look at the development of the USB interface.

  USB is an external bus standard, namely the universal serial bus. The English name is: Universal Serial Bus, so it is referred to as USB, which is used to regulate the connection and communication between the computer and external devices.

   USB was successfully introduced in 1996 after the launch of a combination of Intel and other companies in 1996. It has become a must-have interface for today's computers and a large number of smart devices.

   The USB version has evolved over the years and has grown to version 3.0. The latest generation is USB 3.1, the transmission speed is 10Gbps, the three-stage voltage is 5V/12V/20V, and the maximum power supply is 100W.

   Let's take a look at the generation and speed of USB generations.

USB 1.0

Date of birth: 1996

Speed: 1.5Mbps

Year of upgrade: 1998

Upgrade version: USB 1.1

Speed: 12Mbps

   USB 1.0 was born in 1996, but due to problems with its version, USB 1.1 was re-released in 1998 to improve USB 1.0. USB 1.1 is a more common USB specification and is still available on some older devices. Its high-speed mode has a transmission rate of 12 Mbps and the low-speed mode has a transmission rate of 1.5 Mbps.

USB 2.0

Date of birth: 2000

The USB1.1 specification evolved

Speed: 480Mbps

   The birth of the USB2.0 specification satisfies the speed requirements of most peripherals, greatly increases the speed and increases the functions of ECN, OTG, etc., subdivides the interface type, and unifies the charging standard. The Enhanced Host Controller Interface (EHCI) in USB 2.0 defines a USB 1.1 compliant architecture, so devices that support USB 1.1 can be used directly on the USB 2.0 interface without worrying about compatibility issues.


USB 3.0

Date of birth: 2008

Speed: 5Gbps

Year of upgrade: 2013

Upgraded version: USB3.1

Speed: 10Gbps

   In 2008, the first motherboard supporting USB3.0 interface appeared at ComputeX, and this USB3.0 was officially launched. The USB 3.0 Promoter Group, composed of industry giants such as Intel, Microsoft and Hewlett-Packard, announced that USB 3.0 can be widely used in PC peripherals and consumer electronics.

In order to better standardize USB

The USB organization unifies the names of the various standards:


USB 1.0's 1.5Mbps speed is called Low-Speed

USB 1.1's 12Mbps is called FullSpeed

USB 2.0 480Mbps is called HighSpeed

USB 3.0 era is called Super-Speed

   In 2013, the USB specification was further improved. It is also the latest version of USB3.1. The USB3.1 transmission speed reaches 10Gbps, which is twice that of USB3.0. It has three-stage voltage of 5V/12V/20V and maximum power supply of 100W. Because of its wider application, higher versatility, and faster transmission speed, it will become the next mainstream interface specification.


   In the 2018, the new mobile SSD Peter Pan T100 adopts the latest USB3.0 specification, and the reading speed reaches 420MB/s, which is convenient to carry and supports mobile office in all directions.

   The USB interface can still be a product with potential development value in the future. Following the development of various peripheral equipments, regardless of its shape and performance, it will be more perfect and more suitable for people's needs. We look forward to USB for human life.
