USB 3.2 Aims To Double Data Transfer Speeds for New Devices

The latest standard for USB connections will double data and power transfer speeds for new devices, while remaining compatible with older devices using earlier versions of the electronics connector system. By using multiple, rather than single, wire lane pairs in USB Type-C cables to transmit or receive data, the new standard will support operation speeds of up to 20 Gbps, an improvement over the 10 Gbps supported by the older USB 3.1 standard.

Announced yesterday by the USB 3.0 Promoter Group, the USB 3.2 specification is currently in a draft review stage. It is expected to be formally released to coincide with the USB Developer Days conference set to be held in late September in Vancouver, Canada.

Early details about the USB 3.2 specification are being released now to allow developers to begin designing USB Type-C cables and products that can support the new technology standard. More information and training will be provided for developers at the coming Vancouver event, according to the USB 3.0 Promoter Group, which develops standards for universal serial bus connectors.

‘Next Level of Performance’

“When we introduced USB Type-C to the market, we intended to assure that USB Type-C cables and connectors certified for SuperSpeed USB or SuperSpeed USB 10 Gbps would, as produced, support higher performance USB as newer generations of USB 3.0 were developed,” USB 3.0 Promoter Group chairman Brad Saunders said in a statement. “The USB 3.2 update delivers the next level of performance.”

To gain the full transfer speed improvements of the new standard, users will need a certified USB Type-C cable and a new USB 3.2 device that’s compatible with the updated specification, according to the statement. The update is part of the group’s ongoing USB performance roadmap.

“With increased performance and seamless compatibility, the new USB 3.2 specification brings even more…
