Multi-mode integrated circuit devices including mode detection and methods of operating the same |
摘要 |
Multi-mode integrated circuit devices on an integrated circuit substrate include a controller configured to operate in a first mode compliant with the International Standard Organization (ISO) specification ISO 7816 and a second mode different from ISO 7816 responsive to a mode selection signal. A first plurality of input/output pads are associated with operations in the first mode and a second plurality of input/output pads are associated with operations in the second mode. A mode detector circuit is coupled to at least one of the second plurality of input/output pads and configured to detect connection of the at least one of the second plurality of input/output pads to an external device and to activate the mode selection signal to select the second mode responsive to detection of connection of the at least one of the second plurality of input/output pads to the external device.
