    Abstract: A power supply generates a power supply signal to provide electric power over a USB type-C bus. The power supply includes temperature sensing circuitry which senses indications of temperature of the power supply. Control circuitry coupled to the power supply circuitry and the temperature sensing circuitry compares indications of temperature sensed by the temperature sensing circuitry to three thresholds. The control circuitry determines a limit on available electric power provided by the power supply circuitry over the USB type-C bus based on the comparing. The limit on available electric power is set to one of three or more power levels based on the comparing.

    Abstract: Requests are received by a routing circuit. A plurality of first round-robin arbitration circuits are coupled to the routing circuit. There are as many first round-robin arbitration circuits as there are possible priority levels for the requests. The routing circuit operates to transmit each received request to a number of first round-robin arbitration circuits determined according to the priority level of the request. A second round-robin arbitration circuit has inputs respectively connected to the outputs of the first round-robin arbitration circuits.

    Abstract: A carrier substrate includes a first network of electrical connections and recess. An electronic chip is mounted to the carrier substrate within the recess. The electronic chip includes an integrated guide of optical waves and a second network of electrical connections. A end section of an elongate optical cable is mounted on one side of the electronic chip with a longitudinal guide of optical waves optically coupled to the integrated guide of optical waves. Electrical connection elements are interposed between a face of the electronic chip and a bottom wall of the recess, such that first connect pads of the first electrical connection network are connected to second connect pads of the second electrical connection network through the electrical connection elements.

    Abstract: A scan chain for testing a combinatorial logic circuit includes a first scan chain path of flip-flops connected to the combinatorial logic circuit for functional mode operation during runtime of the combinatorial logic circuit. A second scan chain path of flip-flops is also connected to the combinatorial logic circuit and supports both a shift mode and a capture mode. The second scan chain path operates in shift mode while the first scan chain path is connected to the combinatorial logic circuit for functional mode operation. The second scan chain is then connected to the combinatorial logic circuit when run time is interrupted and operates in capture mode to apply the test data to the combinatorial logic circuit.

    Abstract: A microcontroller includes distinct electronic functions and an interconnection circuit capable of transmitting in wireless fashion data between the functions. The microcontroller can be operated by writing configuration characteristics into a memory of the interconnection circuit for electronic functional circuits that do not have configuration characteristics contained in the memory and erasing configuration characteristics from the memory for electronic functional circuits that have configuration characteristics contained in the memory but are determined to not be able to wirelessly communicate with the interconnection circuit. Data can be wirelessly transmitted between the interconnection circuit and electronic functional circuits having configuration characteristics contained in the memory.

    Abstract: A method for reading or writing data at an address of a memory is disclosed. The data includes a number of consecutive words that each has a plurality of bits. The words are transferred to or from the memory in synchronization with a clock signal so that each word is transferred in one cycle of the clock signal. The bits are scrambled or unscrambled by applying a logic function to the bits of each word. The logic function is identical for the scrambling and the unscrambling and makes use of a bit-key that is dedicated to the word and is identical for the scrambling and the unscrambling. Each bit-key comes from a pseudo-random series generated based on the address.

    Abstract: A method of measuring the phase of a response signal relative to a periodic excitation signal, comprises the steps of producing for each cycle of the response signal two transitions synchronized to a clock and framing a reference point of the cycle; swapping the two transitions to confront them in turns to the cycles of the response signal; measuring the offsets of the confronted transitions relative to the respective reference points of the cycles; performing a delta-sigma modulation of the swapping rate of the two transitions based on the successive offsets; and producing a phase measurement based on the duty cycle of the swapping rate.
