11、Switzerland ii 0 ISO/IEC ISO/IEC 7816-3:1997(E) Foreword IS0 (the International Organrzatron for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the devel

12、opment of International Standards through technical committees esta- blished by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organrzations, governmental and non-governm

13、ental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technrcal committee, lSO/IEC JTC 1. Draft International Standards adopted by the jornt technrcal committee are circulated to national bodies for voting. Public

14、ation as an International Standard requrres approval by at least 75 % of the national bodies casting a vote. International Standard ISO/IEC 7816-3 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 17, Identification cards and related devices. This secon

15、d edition cancels and replaces the first edition (lSO/IEC 7816-3:1989), whrch has been technically revised. It also incorporates Amendment 1 :I 992 and Amendment 2:1994. ISO/IEC 7816 consists of the following parts, under the general title information technology - Identification cards - Integrated c

III ISO/IEC 7816-3:1997(E) 0 ISO/IEC Introduction ISO/IEC 7816 is a series of International Standards describing the parameters fo

18、r integrated circuit(s) cards with contacts and the use of such cards for international interchange. The integrated circuit(s) cards with contacts are identification cards intended for information exchange negotiated between the outside and the integrated circuit within the card. During each informa

19、tion exchange, the card delivers information (computation results, stored data) and/or modifies its content (data storage, event memorization). During the preparation of this International Standard, information was gathered concerning relevant patents upon which application of this standard might de

20、pend. Relevant patents were identified in France and USA, the patent holder being Bull S.A. in each case. However, IS0 cannot give authoritative or comprehensive information about the evidence, validity or scope of the patents or similar rights. The patent holder has stated that licenses will be gra

21、nted in appropriate terms to enable the application of this part of ISO/IEC 7816, provided that those who seek licenses agree to reciprocate. Further information is available from BULL S.A.

35、efines two classes of operat- ing conditions. Through contact VCC, the Interface device shall provide to the card the following nominal supply voltage: l 5 V under class A, l 3 V under class B. Consequently, cards and interface devices shall work either in class A only, or In class B only, or in cla

36、ss A and in class B, denoted as class AB later on. Class A cards shall operate with class A and class AB interface devices. Class AB cards shall operate with class A, class B and class AB interface devices. Class B cards shall operate with class B and class AB interface devices; they shall be design

37、ed in such a way that they will not be damaged under class A operating conditions (by definition, a damaged card no longer operates as specified or contains corrupt data). 4.2.2 Selection of the operating class Figure 1 shows the decisions to be made by an interface devtce in selecting the class of

38、operating conditions to be applied to a card. Decisions shown are based upon information implicit in the interface device, except where the word “card” is present. When available in the interface device, the first operating conditions to be applied to the card shall be class B. Under class A operati

39、ng conditrons, a class B card shall not provide an Answer-to-Reset (see 6). If the card does not provide an Answer-to-Reset, then the interface device shall deactivate the card; after a delay of at least 10 ms, the interface device shall apply the operating conditions of the next available class. If

40、 the card provides an Answer-to-Reset without a class indicator (see 6.5.61, then the Interface devrce shall apply or maintain class A operating conditrons when available, or deactivate the card. If the card provrdes an Answer-to-Reset with a class indicator, and the Interface device is applying a c

41、lass of operatrng conditions supported by the card, then normal operation may continue. If the Answer-to-Reset does not indicate the current class of operating condrtrons, but another class supported by the interface device, then the interface device shall deactivate the card; after a delay of at le

42、ast 10 ms, the Interface device shall apply the operating conditrons of that class. NOTE -Some cards conformrng to ISO/IEC 781 - state A if thts state is imposed by the transmitter. When the two ends of the line are in reception mode, the line shall be at state Z (high state). When the two ends are

43、in non-matched transmit mode, the logic state of the line may be Indeterminate. During operation, the interface device and the card shall not both be in transmit mode. The interface device shall be able to support the defined range of input currents when the input voltages are in the allowed range.

44、The interface device shall present to the card an impedance such that it will not prevent the card from being able to keep the output voltages in the defined range.

The actual value of the frequency of the clock signal IS designated by f. See 5.2 and 6.5.2 for the ranges of values of f. The duty cycle of the clock signal shall be bet

47、ween 40 % and 60 % of the period during stable operation. When switching the frequency from one value to another, care should be taken to ensure that no pulse is shorter than 40 % of the shortest penod allowed by the card as defined in table 7. No information shall be exchanged when switching the fr
