USB-ICC
IJS8 Integrated Cwcuit Card. An integrated cwcuit card Providing a USB interlace,
5 Electrical characteristics of the contacts
The assignment of the contacts for USB operating conditions is given in ISO/IEC 7816-2:1999 and ISQ’IEC 78162:1 999Amd.1 :2004.
An interface device will provide a USB connection to a USB-IGC through VCC, GND, AUX1 and AUX2 respectively VBLJS, GND. D. and D- defined by the USB specification.
Cards designed tar ISOIEC 7816-3 operating conditions shall not be damaged when activated under USB conditions. Conversely, cards designed br IJSB operation shall not be damaged when activated under ISOIEC 7816-3 operating conditions (by definition, a damaged card no longer operates as specified or contains corrupt data)
6 USB-ICC operated by an interface device
A U SB-ICC that only provides a US8 interface shall have electncally connected Cl, C5. C4 and Ca. All other contact fields shal be electncaly isolated. This type of USB-ICC can be operated by a USB connection device. The liSa connection device shall estalsh an electrical connection to Cl. CS. C4 and C8 only. blowing the electrical characteristics and protocol grven in the USB specification.
An interface device that does not support a US8 interface shall have AUX1 and AUX2 electrically isolated or ensure that the voltage appled at these contact fields shal remain between -O,3V and Vcc • O,3V.
