ABSTRACT:
A dual mode smart card controller is provided. In one embodiment, a USB and ISO7816 smart card controller is provided that determines the type of card that is inserted into a slot. If the smart card is a USB smart card, the controller is adapted to pass control of the smart card to an external PC host USB hub circuit. If the smart card is an ISO7816 card, then control is handled by the dual mode controller. In another embodiment, the controller includes an embedded USB hub circuit to permit the controller to directly control both USB and ISO7816 smart cards. Exemplary control sequencing includes monitoring a C4 signal line for a preselected time period, or generating an enable signal if a USB smart card is detected.
