标准范围

ISO/IEC 7816-12:20 05规定了提供USB接口的集成电路卡的操作条件。具有USB接口的集成电路卡称为USB-ICC.ISO/IEC 7816-12:20 05规定了USB-ICC由接口设备操作时的电气条件——对于那些未使用的接触场,当USB接口应用时;USB标准描述符和USB-ICC类特定描述符;使用批量传输或控制传输在主机和USB-ICC之间传输数据;允许称为版本A和版本B的两种不同协议的控制转移;(可选的)中断传输以指示异步事件;状态和错误条件。ISO/IEC 7816-12:20 05为控制转移提供了两种协议。这是为了支持协议T=0(版本A)或使用APDU级别上的传输(版本B)。ISO/IEC 7816-12:20 05为每个传输(批量传输、控制传输版本A和版本B)提供了USB-ICC的状态图。USB-ICC必须能够处理的可能序列的示例在信息性附件中给出。

ISO/IEC 7816-12:2005 specifies the operating conditions of an integrated circuit card that provides a USB interface. An integrated circuit card with a USB interface is named USB-ICC.

ISO/IEC 7816-12:2005 specifies

  • the electrical conditions when a USB-ICC is operated by an interface device - for those contact fields that are not used, when the USB interface is applied;
  • the USB standard descriptors and the USB-ICC class specific descriptor;
  • the data transfer between host and USB-ICC using bulk transfers or control transfers;
  • the control transfers which allow two different protocols named version A and version B;
  • the (optional) interrupt transfers to indicate asynchronous events;
  • status and error conditions.


ISO/IEC 7816-12:2005 provides two protocols for control transfers. This is to support the protocol T=0 (version A) or to use the transfer on APDU level (version B). ISO/IEC 7816-12:2005 provides the state diagrams for the USB-ICC for each of the transfers (bulk transfers, control transfers version A and version B). Examples of possible sequences which the USB-ICC must be able to handle are given in an informative annex.
