  • Multiple element interface
    Patent number: 5655092
    Abstract: The object of the invention is an expanded PCMCIA interface and a method for identifying such an expanded interface. According to the invention, among the power transmission pins of a standard PCMCIA interface, two of which are reserved for operating voltage and four for ground potential (P1, P2, P3, P4), maximally one operating voltage pin and three ground potential pins (P1, P2, P3, P4) have been redefined such that they are connected to a different voltage than standard voltage (GND, GND, VCC). This allows analogue and/or digital signals to be transferred through the redefined pins. Each redefined pin is preferably provided with a resistance coupling (Ra, R2, R3), by means of which the voltage prevailing in the redefined pin (P1, P2, P3, P4) has been raised (VCC) respectively dropped (GND) compared to the ground potential (GND) and operating voltage (VCC) of a standard pin.
