What is USB Type-C and Why We are Excited About It
Thursday, August 20th, 2015 | Author: Elaine

USB Type-C is an USB interface(connector) defined by USB Implementers Forum, Inc., creators of USB technology. Welcome to USB Type-C! Apple’s new MacBook has implemented the USB Type-C port, which will be the future modern product of USB Port.

USB Type-C Features

USB Type-C Features

From the shape, USB type C is greatly different from the common USB Type A. Although the USB technology has developed from the USB 2.0 to USB 3.0, and USB 3.1, the appearance of the port we mostly use is USB Type A, which has a right and wrong side when you plug it in.

With the newly designed USB type C, you needn’t worry about reversing the usb cable when plugging it in.

Let’s first get an overview of USB type C, except this easy plug feature.

  1. USB Type-C is a specification for a reversible-plug connector for USB devices and USB cabling.
  2. Rather slimmer and thinner than USB type-A.
  3. typeA and type C

    USB Type-A (Left) and USB Type-C(Right)

    As the following picture shows, the right side USB type-c is much smaller and thinner than the left USB Type-A. A Type-C port measure is just 8.4mm by 2.6mm. This means it’s small enough to work for even the future smallest peripheral devices.

  4. USB type C is USB 3.1 standard. High Speed as 10M bps and as a power port. 2X  Transferring speed of the USB 3.0.
  5. The USB-C connector supports DisplayPort, HDMI, power, USB, and VGA. Notably absent is Thunderbolt.
  6. USB Type-C is backward compatible but requires adapters. It’s fully compatible electrically with USB 3.0, though obviously it won’t plug in physically without an adapter. It is fresh that USB needs an adapter.
  7. Power Supports:

Indications are that the USB-C standard supports at least 100 watts of power delivery, so it’s possible that USB-C could replace most power adapters as a standard in the future. Using USB to power a laptop isn’t new, though. Look at the Lenovo Yoga 3 Pro $1,299.00 at Lenovo, which has a full-size USB 3.0 power connector.

Look at the connector interface of USB type-C.

Are there any latest USB Type-C applications in consumer products?

Yes. There are booming. Besides the Apple MacBook port, there are more and more USB Type c products emerge.

Watch this Video about USB type-c by expert of PCmag:

I have collect some USB Type C products in the latest days:

  • Lattice Semiconductor Expands USB Type-C Product Family
  • Asus Releases ZenPad Flagship With USB Type-C
  • Google Nexus 5 2015 Release Update: Fingerprint Sensor, USB Type C

For Adapters:

The majority of USB type-c adapters are the USB Type-C to USB Type-A adapters.

USB type-c to USB 2.0 adapters for power

USB type-C to USB 2.0 female cable

USB Type-C to Mini USB data power adapter

Apple USB Type-C to USB Adapters.

Thought we need adapters to transferring data between USB Type C and common USB products. It is not long before we do not need adapters when the USB Type-C becomes more popular.

USB Implementers Forum, which is the creator of USB Type-C, says that Type-C USB is designed to be future-proof. In the future, there will be more and more USB Type-C devices for the fastest USB connectors. When USB Type-C becomes as popular as the current USB Type-A, it will be easier when we working with devices. We will hold tiny USB devices for both data and power connections. Just welcome the smart digital connection and cables of USB Type-c of USB 3.1

What is USB 3.1 and Faster USB 3.1 Features

What is USB 3.1 and when it was released

USB Technology develops fast as the modern technology is blooming in data transmitting. We have already known well about USB 3.0. USB 3.0 is widely used for data transfer among popular devices, such as PCs, tablets, hybrids, and mobile phones.USB 3.0 was first announced by USB Promoter Group in 2008. The new standard offers 10 times of the data transfer speed vs. USB 2.0 and is high efficiency that is 5.0Gbps.

When is the USB 3.1 release date?

The USB 3.1 is released on Dec. 23th, 2013 by USB 3.0 Promoter Group, which is the highest level of USB standards until now with the fastest data transfer speed.

Why do we need faster data transfer speed?

This picture from Kingston.com can interpret our needs for data transferring clearly.

why we need that speed of USB

Faster USB 3.1 Specification

USB 3.1 has a 10gbps speed. And deliver twice the effective data performance than USB 3.0. It is fully compatible backward with USB cables and connectors.

The specification is as the following:

• Delivers 10 Gbps USB data rate

* 2x improvement over current USB3.0 5 Gbps data rate

• Improved data encoding for more efficient data transfer leading to higher through-put and improved I/O power efficiency

• Compatible with existing USB 3.0 software stacks and device protocols

• Works with both existing 5 Gbps USB 3.0 hubs and devices, as well as USB 2.0 products

In common words, USB 3.1 is faster and more powerful than before, but it also consumes more power. With its release, the new Type-C 3.1 as a new cable and connectors is also introduced.

There are three connector of interfaces for USB 3.0(Superspeed+), Type-A(standard-A), Type-B(Micro-B) and Type-C.

typeA and type C

TypeA and type C USB 3.1 Port

Type B of USB 3.1 Port

Type B of USB 3.1 Port

Type-A(standard-A) is the most widely used interface for connecting. Micro-B is mainly used in Smartphone and tablets. And the newly introduced Type-C 3.1 is used for lighter and thinner, and slimmer devices.

Supply better power Charge

USB 3.0 Promoter Group has said that the USB 3.1 connector and port are designed to accommodate future updates, making them future-proof.

Also, the Type-C 3.1cable can charge your tablets, smartphones and other devices faster with its up to 100 watts.

The test by Asus of USB 3.1

According to the technology reports from Asus Z97A usb 3.1, when the speed testing software continuously reading and writing, the reading speed comes up to 781.2MB/S, and the writing speed 797.8MB/S. The same environment of USB 3.0 test result is separately 446.5 MB/S and 448.6 MB/S. We can see the efficiency of USB 3.1 clearly.

The Competition from Intel

The only rival is Intel’s Thunderbolt technology, which is found primarily in Apple’s laptops and desktops. While as to the cost, USB have great advantage. Acer, as one of the world’s largest computer manufacturers, announced that it would favor USB 3.1 over Thunderbolt in all future devices.

Pamper Imagination of the Future.

Look forward to more USB 3.1 devices blooming in our daily life. The usb 3.1 is the most powerful USB interface with type-c. There will be more and more devices like computers, tablets, and computer calculating interface to apply the USB 3.1 interface. And the future advanced devices with the most efficient USB port will supply us faster speed for data transferring. We will have better experience in multimedia data applications. Let’s wait for more USB 3.1 devices.
