Universal serial bus interfaces for data and power - Part 1-3: Common components - USB Type-C® Cable and Connector Specification

IEC 62680-1-3:2021 defines the USB Type-C™ receptacles, plug and cables. The USB Type-C Cable and Connector Specification defines a new receptacle, plug, cable and detection mechanisms that are compatible with existing USB interface electrical and functional specifications. This specification covers the following aspects that are needed to produce and use this new USB cable/connector solution in newer platforms and devices, and that interoperate with existing platforms and devices: - USB Type-C receptacles, including electro-mechanical definition and performance requirements - USB Type-C plugs and cable assemblies, including electro-mechanical definition and performance requirements - USB Type-C to legacy cable assemblies and adapters - USB Type-C-based device detection and interface configuration, including support for legacy connections - USB Power Delivery optimized for the USB Type-C connector. This specification is intended as a supplement to the existing USB 2.0, USB 3.1 and USB Power Delivery specifications. It addresses only the elements required to implement and support the USB Type-C receptacles, plugs and cables. Normative information is provided to allow interoperability of components designed to this specification. Informative information, when provided, may illustrate possible design implementations. IEC 62680-1-3:2021 cancels and replaces the third edition published in 2018 and constitutes a technical revision. New release primarily for enabling USB4 over USB Type-C connectors and cables. Also includes incorporation of all approved ECNs as of the revision date plus editorial clean-up.

Interfaces de bus universel en série pour les données et l'alimentation électrique - Partie 1-3 : Composants communs - Spécification des câbles et des connecteurs USB Type-C®

L'IEC 62680-1-3:2021 définit les connecteurs mâles et femelles, ainsi que les câbles USB Type-C™. La spécification des câbles et connecteurs USB Type-C est guidée par les principes suivants: - favoriser des critères de forme d'hôtes et dispositifs innovants et agréables, pour lesquels la taille, la conception industrielle et le style sont des paramètres importants; - travailler en toute fluidité à partir des solutions USB existantes pour les hôtes et dispositifs en silicium; - améliorer la facilité d'utilisation pour la connexion de dispositifs USB, en réduisant autant que possible le risque de confusion du sens d'insertion du connecteur mâle et des câbles. La spécification des câbles et connecteurs USB Type-C définit de nouvelles techniques de connexion et détection des ports et des câbles USB, compatibles avec les spécifications électriques et fonctionnelles d'interface USB existantes. La présente spécification couvre les aspects suivants, nécessaires à la production et à l'utilisation de cette nouvelle solution de câble/connecteur USB pour les plateformes et les dispositifs récents, qui interagissent avec les plateformes et les dispositifs existants: - connecteur femelle USB Type-C, y compris la description électromécanique et les exigences de performance; - connecteurs mâles et ensembles câble-connecteur USB Type-C, y compris la description électromécanique et les exigences de performance; - ensembles câble-connecteur et adaptateurs USB Type-C permettant la connexion vers les solutions existantes; - configuration d'interface et détection des dispositifs basées sur USB Type-C, y compris la prise en charge des solutions de connexion existantes; - technologie d'alimentation électrique par USB optimisée pour les connecteurs USB Type-C. La spécification des câbles et connecteurs USB Type-C définit une technique normalisée prenant en charge des modes alternatifs, tels que la reconversion du connecteur pour un usage spécifiquement lié au branchement. L'IEC 62680-1-3:2021 annule et remplace la troisième édition parue en 2018, dont elle constitue une révision technique. Nouvelle version essentiellement destinée à l'application de la spécification USB4 aux câbles et connecteurs USB Type-C. Comprend également l'incorporation de l'ensemble des ECN approuvés à la date de révision, ainsi que les corrections rédactionnelles.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all

national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-

operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition

to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly

Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is

entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in

this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also

participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO)

in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all interested

IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation

by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between any

IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services

carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members

of its technical committees and IEC National Committees for any personal injury, property damage or other damage

of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of

the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62680-1-3 has been prepared by technical area 18: Multimedia home

systems and applications for end-user networks, of IEC technical committee 100: Audio, video and

multimedia systems and equipment.

INTRODUCTION

The IEC 62680 series is based on a series of specifications that were originally developed by the

USB Implementers Forum (USB-IF). These specifications were submitted to the IEC under the

auspices of a special agreement between the IEC and the USB-IF.

This standard is the USB-IF publication Universal Serial Bus Type-C Cable and Connector

Specification Revision 2.0.

The USB Implementers Forum, Inc.(USB-IF) is a non-profit corporation founded by the group of

companies that developed the Universal Serial Bus specification. The USB-IF was formed to

provide a support organization and forum for the advancement and adoption of Universal Serial

Bus technology. The Forum facilitates the development of high-quality compatible USB peripherals

(devices), and promotes the benefits of USB and the quality of products that have passed

compliance testing.

THE PROVISION OF ANY USB SPECIFICATIONS TO YOU DOES NOT PROVIDE YOU WITH
ANY LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE, TO ANY
INTELLECTUAL PROPERTY RIGHTS.

Entering into USB Adopters Agreements may, however, allow a signing company to participate in

a reciprocal, RAND-Z licensing arrangement for compliant products. For more information, please
