Originally intended as a replacement for serial and parallel connections on a PC
to connect mice, keyboards and printers. Universal Serial Bus has grown to become
a common interface in many embedded industrial, medical, automotive,
and consumer applications. Highfive Electronics USB solutions are
designed to support the growing needs of these markets with a full
complement of robust, highly integrated USB MCUs and DSCs,
and USB Hubs and Devices.

Type-C is a form of USB interface that is currently used by the mainstream. Its full name is: USB Type-C. Its core features can be summarized in the words “fast, strong and small”. Compared with the traditional interfaces of previous generations, Type-C can support charging, data transmission, image transmission and other functions at the same time, and truly realize the powerful purpose of “multi-purpose”.
In 2014, the Type-C interface standard was officially born. Subsequently, Apple completely canceled the power interface, USB interface, DP interface, HDMI interface, and VGA interface on the Macbook notebook computer released in 2015, and integrated it into a Type-C interface to realize all the above functions. As a result, the Type-C interface is completely on fire.
The Type-C interface mainly has the following advantages
1, the interface is smaller. Compared with the past USB Type-A interface, Type-C greatly reduces the interface area, and is more suitable for application in various thin-sized equipment products;
2, support “positive and negative blind insertion”. Since the front and back sides of the Type-C interface are designed exactly the same, the “positive and negative blind insertion” function is perfectly realized, and users do not need to worry about the trouble of “USB always inaccurate”;
3, it supports fast charging and bidirectional charging. The Type-C interface supports the USBPD protocol, that is, the power transmission protocol, which can achieve higher voltage and current. It can be expanded to an output voltage of 20V and an output current of up to 5A, which is a maximum output power of 100W, which greatly improves the charging speed.
In addition, it can freely change the direction of power transmission, both to charge itself and to charge external devices in reverse. Based on this principle, we can use a USB Type C to C cable to achieve series charging.
4, it supports the USB3.1 standard, and the maximum data transmission speed can reach 10Gbit/s. However, not all Type-C interfaces support the USB3.1 standard, and it can also only support transmission protocols such as USB2.0 and USB3.0, which needs special attention.
5, extremely rich functional scalability. As mentioned earlier, the Type-C interface integrates functions such as charging, data transmission, and image transmission. In other words, only one Type-C interface cable is used to solve different interface cables such as HDMI, DVI, and VGA.
In summary, Type C is not only extremely advanced in function, but also has a smaller size and higher compatibility and performance. Therefore, it has been widely used in various electronic products such as computers, smartphones, tablets, peripheral accessories, and storage hard drives. It has gradually become a mainstream unified interface recognized by the public.
What’s more worth mentioning is that after the emergence of the latest USB3.1 transmission standard, the Type C interface has become the only recommended interface. In the Thunderbolt Thunderbolt 3 interface launched by Apple and Intel in depth, the previous miniDP was also changed to USB Type C. These changes have undoubtedly promoted the Type C interface to achieve the vision of “unification” in the future.e
