|Publication Date:||1 February 2021|
The present document specifies the Inter-Chip USB interface between the USB UICC and the USB UICC-enabled terminal, subsequently referred to as the IC-USB interface. It describes:
• the characteristics of the Inter-Chip USB electrical interface between the USB UICC and the USB UICC-enabled terminal;
• the initial communication establishment and the transport protocols;
• the communication layers between the USB UICC and the USB UICC-enabled terminal.
The physical characteristics (including mechanical aspects) defined in ETSI TS 102 221  apply to USB UICCs. The present document comes as an extension of ETSI TS 102 221  complementing the electrical characteristics of contacts C1 and C5 and describing the behaviour of contacts C4 and C8 when the USB interface is supported.
The Inter-Chip USB interface provides access to the existing UICC resources such as the file system and security features specified in ETSI TS 102 221  and to other resources and functionalities specified in the present document.
