The new USB 3.2 standard has been announced, offering transfer rates up to 20 Gbps (2GB / s), twice the maximum speed available with the second generation USB 3.1 standard. Currently, USB 3.2 is in the design phase, with the standard expected to be complete by September. The ad came on July 26 from the USB Implementers Forum, the group that develops USB standards.
The new USB 3.2 standard will only be available through USB-C ports and cables. USB Type-A (left) and Type-B (right) connectors have enough ‘wires’ to transport such a quantity of data. The current USB-C cables that can reach 10 Gbps through the 2nd generation USB 3.1 standard are expected to be compatible with the USB 3.2 standard.
To make it clear between USB-C and USB 3.1 / 3.2, USB ‘xx’ technology as 3.1 defines how data is transferred through cables, while USB-Type A / B / C technology is a physical specification that defines connections Of ports and connectors.
The C-type connector was introduced with the USB 3.1 and brought with it some novelty, including the ability to charge devices that require more than 25 W via two new pins. The USB-C is set to become the new standard for charging cell phones, tablets and laptops. One advantage of USB-C connectors is that they are reversible, so you do not have to worry about controlling the direction in which the cable is attached.
Once the USB 3.2 specifications are finalized by September, manufacturers will need some time to bring the first USB 3.2 devices on the market – it is estimated that they could serve 12 to 18 months, so do not expect devices with this before 2019.
We will update the article when the USB 3.2 standard will be finalized and submitted later this summer.
