  • Publication number: 20230252258
    Abstract: A contactless communication device includes an electronic integrated circuit chip and an antenna coupled to the electronic integrated circuit chip to supply an electric signal for powering the electronic integrated circuit chip. An ambient luminosity detection element is coupled to the electronic integrated circuit chip.

  • Publication number: 20230223989
    Abstract: A near-field communication circuit of a first NFC device alternates, in low power mode, between: first phases of emission of field bursts and second phases spanning an entire duration separating two successive first phases. Each second phase includes a field detector enabling phase. In one implementation, the field detector enabling phase extends all along a duration of the second phase. In an alternate implementation, the field detector enabling phase is interrupted by field detector disabling phases. Each field detector disabling phase has a duration shorter than a minimum duration of each first phase.

  • Publication number: 20230189149
    Abstract: In the case of a potential detection, by a first near field communication (NFC) device, of a second NFC device, a validation of this detection is performed according to the time variation gradient of at least one environmental condition of the first device. A value of one of an amplitude and an phase of a signal across an oscillating circuit of the first NFC device is compared to first thresholds to potentially detect the second NFC device. Validation of detection occurs when one of the amplitude and the phase of the signal is outside the first thresholds adjusted as a function of the time variation gradient. Validation detection also occurs when one of the amplitude and the phase of the signal adjusted as a function of the time variation gradient is outside the first thresholds.
