A novel concept for Near Field Communication (NFC) is described herein. In accordance with the embodiments described herein, orthogonal carrier signals are transmitted between NFC transmitter and NFC receiver circuit. In one arrangement, a carrier signal is unmodulated to ensure uninterrupted energy transfer to the receiver circuit. The orthogonal carriers are used to implement full-duplex Near Field Communication.

Modulation technique for near field communication

According to one embodiment a circuit comprises a supply pin operable to receive a supply voltage, a non-volatile memory for storing one or more parameters, and a Near Field Communication (NFC) transceiver that is operable to receive data representing the one or more parameters. The circuit is operable to deactivate the NFC transceiver in response to receiving the supply voltage at the supply pin.

Power regulation for lighting using NFC

An electronic device is described herein. In accordance with one embodiment, the electronic device includes an embedded controller having a debug logic, an interface circuit coupled to the debug logic, and a memory coupled to the interface circuit. The interface circuit is operative to read debug information stored in the debug logic and to transmit the read debug information to the memory. The interface circuit is further operative to receive debug information stored in the memory and write the received debug information into the debug logic.

Microcontroller system with in-circuit debugger

A semiconductor device for outputting a control parameter includes a receiving unit, a storage unit and an output unit. The semiconductor device also contains antenna connections, supply connections and at least one output connection for outputting a control parameter signal. The receiving unit contains connections for connection to an antenna, from which the receiving unit receives signals. The receiving unit converts the signals received from the antenna into data. The data are stored in the storage unit. The semiconductor device outputs an output signal at the output connection on the basis of the data stored in the storage unit. The semiconductor device additionally contains a calculation unit which determines the operating hours (time) of the semiconductor device. The output signal depends both on the data stored in the storage unit and on the determined operating hours (time).

Semiconductor device for outputting a control parameter

A control circuit for a switching converter is described herein. In accordance with one embodiment the control circuit includes an analog bus that receives a plurality of input signals and a first set of functional units that are operable to receive at least some of the input signals via the analog bus and to process the input signals to generate digital output data based on the input signals. The control circuit further includes an event bus that has an event bus controller and a plurality of bus lines and a second set of functional units that are operable to receive the output data, via the event bus, from the functional units of the first set. At least one functional unit of the second set of functional units is operable to determine switching time instants for the switching converter based on the output data received via the event bus, and the event bus controller includes an arbiter operable to arbitrate data transmission across the bus lines.
