Abstract
An RFID device (100) being operable in a first and a second operating state, the RFID device comprises a control unit (102), wherein the control unit comprises a configuration input terminal for receiving a configuration signal, and a processing unit (101), which is coupled to the control unit, wherein the control unit is adapted for switching the processing unit between the first and the second operating state based on the configuration signal, wherein the control unit (102) comprises an activation input terminal for receiving an activation signal.
Claims12
An RFID device being operable in a first and a second operating state, the RFID device comprising
- a first control unit including electronic circuitry, a first configuration input terminal and a first activation input terminal, the first control unit configured and arranged to
- receive, via the first configuration input terminal, a first configuration signal, and
- receive, via the first activation input terminal, a first activation signal, and
- operate in an active mode based on reception of the first activation signal, different from the first configuration signal;
- a second control unit including electronic circuitry, a second configuration input terminal and a second activation input terminal, the second control unit configured and arranged to
- receive, via the second configuration input terminal, a second configuration signal,
- receive, via the second activation input terminal, a second activation signal, and
- operate in an active mode based on reception of the second activation signal, different from the second configuration signal;
- and
- a processing unit including electronic circuitry is communicatively coupled to the first and second control units, the processing unit configured and arranged to
- switch, based on at least one of the configuration signals, between a first operating state and a second operating state having higher power than the first operating state,
- generate the first activation signal in response to the first operating state, and
- generate the second activation signal in response to the second operating state.
Method for operating an RFID device in a first and a second operating state, the method comprising:
- receiving a first configuration signal at a first configuration input terminal of a first control unit that includes electronic circuitry,
- receiving a first activation signal at a first activation input terminal of the first control unit,
- operating the first control unit in an active mode based on reception of the first activation signal, different from the first configuration signal,
- receiving a second configuration signal at a second configuration input terminal of a second control unit that includes electronic circuitry,
- receiving a second activation signal at a second activation input terminal of the second control unit,
- operating the second control unit in an active mode based on reception of the second activation signal, different from the second configuration signal;
- switching a processing unit including electronic circuitry, coupled to the processing unit, between the first and the second operating states based on at least one of the configuration signals, the second operating state corresponding to a higher power state than the first operating state, and
- generating, using the processing unit, the first and second activation signals in response to the first and second operating states, respectively,
- activating or deactivating the control units based on receipt of a respective one of the activation signals.
