IEC 62680-4-1:2022

IEC 62680-4-1:2022 provides Universal Serial Bus 4™ Specification. USB 3.1 and USB 3.2 were evolutionary steps to increase bandwidth. The goal for USB4 remains the same with the added goal of helping to converge the USB Type-C® connector ecosystem and minimize end-user confusion. Several key design areas to meet this goal are listed below: • Offer display, data, and load/store functionality over a single USB Type-C connector. • Retain compatibility with existing ecosystem of USB and Thunderbolt™ products. • Define Port Capabilities for predictable and consistent user experience. • Provide increased host flexibility to configure bandwidth, power management, and other performance-related parameters for system needs This document contains USB4™ Specification, Version 1.0 with Errata and ECN through May 19, 2021.
