Universal Serial Bus interfaces for data and power - Part 2-2: Universal Serial Bus - Micro-USB Cables and Connectors Specification, Revision 1.01 (TA 14) (IEC 62680-2-2:2015)
USB has become a popular interface for exchanging data between cell phone and portable devices. Many of these devices have become so small it is impossible to use standard USB components as defined in the USB 2.0 specification. In addition the durability requirements of the Cell Phone and Portable Devices market exceed the specifications of the current interconnects. Since Cell Phones and other small Portable Devices are the largest market potential for USB, this specification is addressing this very large market while meeting all the requirements for electrical performance within the USB 2.0 specification.

L'IEC 62680-2-2:2015 définit les exigences et les caractéristiques d'un connecteur micro-USB pour satisfaire aux besoins actuels et futurs du marché des téléphones mobiles et des dispositifs portatifs, tout en se conformant à la spécification USB 2.0 en ce qui concerne les performances, les dimensions et la forme du dispositif d'interconnexion micro USB.

USB je postal priljubljen vmesnik za izmenjavo podatkov med mobilnimi telefoni in prenosnimi napravami. Številne izmed teh naprav so postale tako majhne, da je z njimi nemogoče uporabljati standardne komponente USB, kot so opredeljene v specifikaciji za USB 2.0. Poleg tega zahteve za odpornost, ki veljajo na trgu mobilnih telefonov in prenosnih naprav, presegajo specifikacije trenutnih povezav. Ker mobilni telefoni in druge majhne prenosne naprave predstavljajo največji tržni potencial za USB, se specifikacija osredotoča na ta izredno velik trg, pri čemer izpolnjuje vse zahteve za električno zmogljivost specifikacije za USB 2.0.

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 62680-2-2 has been prepared by technical area 14: Interfaces and
methods of measurement for personal computing equipment, of IEC technical committee 100:
Audio, video and multimedia systems and equipment.
The text of this standard is based on documents prepared by the USB Implementers Forum

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.
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.
ANY USB SPECIFICATIONS ARE PROVIDED TO YOU "AS IS, "WITH NO WARRANTIES
WHATSOEVER, INCLUDING ANY WARRANTY OF MERCHANTABILITY, NON-
INFRINGEMENT, OR FITNESS FOR ANY PARTICULAR PURPOSE. THE USB
IMPLEMENTERS FORUM AND THE AUTHORS OF ANY USB SPECIFICATIONS DISCLAIM
ALL LIABILITY, INCLUDING LIABILITY FOR INFRINGEMENT OF ANY PROPRIETARY
RIGHTS, RELATING TO USE OR IMPLEMENTATION OR INFORMATION IN THIS
SPECIFICAITON.
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, royalty-free licensing arrangement for compliant products. For more

UNIVERSAL SERIAL BUS INTERFACES
FOR DATA AND POWER –
Part 2-2: Micro-USB Cables and
Connectors Specification, Revision 1.01
1 Introduction
1.1 General
USB has become a popular interface for exchanging data between cell phone and portable
devices. Many of these devices have become so small it is impossible to use standard USB
components as defined in the USB 2.0 specification. In addition the durability requirements of
the Cell Phone and Portable Devices market exceed the specifications of the current
interconnects. Since Cell Phones and other small Portable Devices are the largest market
potential for USB, this specification is addressing this very large market while meeting all the
requirements for electrical performance within the USB 2.0 specification.
1.2 Objective of the Specification
The purpose of this document is to define the requirements and features of a Micro-USB
connector that will meet the current and future needs of the Cell Phone and Portable Devices
markets, while conforming to the USB 2.0 specification for performance, physical size and
shape of the Micro-USB interconnect.
This is not a stand-alone document. Any aspects of USB that are not specifically changed by
this specification are governed by the USB 2.0 Specification and USB On-The-Go Supplement.
1.3 Intended Audience/Scope
Cell phone and Portable Devices have become so thin that the current Mini-USB does not fit
well within the constraints of future designs. Additional requirements for a more rugged
connector that will have durability past 10 000 cycles and still meet the USB 2.0 specification
for mechanical and electrical performance was also a consideration. The Mini-USB could not
be modified and remain backward compatible to the existing connector as defined in the USB
OTG specification.
