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： A communication apparatus and a communication method prevent responses from being simultaneously received from two or more communicating parties. A first NFC apparatus transmits data for requesting IDs, and acquires IDs sent from second and third NFC apparatuses in reply to the request. After acquiring the IDs of the second and third NFC apparatuses, the first NFC apparatus transmits data that includes their IDs as the data for the second and third NFC apparatuses. If the first NFC apparatus cannot properly acquire the IDs of the second and third NFC apparatuses, then it sends the data for requesting their IDs again. Upon receipt of the request for the IDs, the second and third NFC apparatuses generate their own IDs by using random numbers and send the generated IDs. If the second and third NFC apparatuses receive the request for their IDs again, then they re-generate their own IDs by using random numbers, and send the re-generated IDs again. The present invention can be applied to, for example, an IC card system.
