RFID-UHF INTEGRATED CIRCUIT

摘要

The invention concerns a non-contact integrated circuit (IC) comprising an RFID communication interface (1, PSEXT1, MOD1, DEMOD1, CKGEN1) including an antenna coil (L) for receiving a first induced alternating current voltage (Va) when the integrated circuit is in the presence of an RF magnetic field, and a data processing unit (DPU) connected to the first communication interface, the data processing unit being equipped with an electrically programmable and erasable memory (MEM). The invention is characterized in the integrated circuit further comprises a UHF communication interface (2, PSEXT2, MOD2, DEMOD2, CKGEN2) including a UHF antenna (2) for receiving a second induced alternating current voltage (Vb) when the integrated circuit is in the presence of a UHF electric field signal, and multiplexing means (MUX1, MUX2, DMUX) for connecting the data processing unit (DPU) to one or the other of the two communication interfaces.
