    摘要: The present invention relates to a semiconductor integrated-circuit device capable of seamlessly switching a power source obtained by rectifying a carrier wave and an external power source. The semiconductor integrated-circuit device having a non-contact card function and a non-contact reader/writer function includes a rectifier 131 for rectifying a received carrier wave, a serial regulator 132for obtaining a predetermined voltage from an output voltage of the rectifier 131, and a power-supply control circuit 138 for turning on/off the voltage from a battery 160. In a case where the output voltage of the battery 160 is equal to or higher than a predetermined voltage, the power-supply control circuit 138 selects the voltage of the battery 160 as power required for operation of an IC 300 when a reader/writer mode signal or a card mode signal is received. On the other hand, when the output voltage of the battery 160 is lower than the predetermined voltage, the power-supply control circuit 138 selects the output voltage from the rectifier 131 as power required for operation of the IC 300. The present invention can be applied to a portable terminal, such as a cellular phone.

    摘要: When an IC card is passed over an external card reading and writing apparatus, the IC card starts communication with the card reading and writing apparatus via a wireless interface, so that a change in the internal state of the IC card is reported to an external device via an external wired interface or a dedicated control signal line, thus allowing a specific application to be enabled on the external device or allowing a controller to be powered on and activated. Alternatively, the controller is powered off and deactivated. Accordingly, processing according to the communication state between the IC card and the card reading and writing apparatus or the internal state of the IC card can be smoothly initiated.

    摘要: The present invention relates to a communication system, a communication device, and a communication method for easily solving a problem of a hidden terminal. Communication devices 1 and 3 determine whether or not an electromagnetic wave at the level of a magnetic-flux density TH1 or more for determining the suppression of the output of carrier. When the electromagnetic wave at the level of the magnetic-flux density TH1 or more for determining the suppression of the output of the carrier is not detected, the communication devices 1 and 3 start the output of the electromagnetic wave. A communication device 2 needs the electromagnetic wave at the level of a magnetic-flux density TH2 or more of the carrier at an operating limit, which is higher than the magnetic-flux density TH1 for determining suppression of the output of carrier so as to obtain data via the electromagnetic wave. The present invention is applied to, e.g., an IC (Integrated Circuit) card system.
