    Abstract: A system on a chip comprising a set of one-time programmable memory elements that comprises a first valid configuration; a second valid configuration; and a plurality of invalid configurations. The system on a chip also comprises a programming indicator initially comprising a first value and configured to be permanently set to a second value. The system on a chip further comprises a decoder circuit in communication with the set of one-time programmable memory elements to determine whether the set of one-time programmable memory elements is in the first valid configuration, the second valid configuration, or any one of the plurality of invalid configurations. The decoder circuit generates a threat-detection signal when the set of one-time programmable memory elements is in any of the plurality of invalid configurations when the programming indicator is permanently set to the second value.

    Abstract: In an embodiment an envelope detection device includes an input terminal configured to receive an amplitude-modulated radio frequency signal, a first resistive element and a first MOS transistor connected in parallel between the input terminal and a first node configured to receive a reference potential, a first capacitive element connected between a gate of the first MOS transistor and the first node, an envelope detection circuit connected to the input terminal and configured to supply a voltage representative of an envelope of the amplitude-modulated signal and a circuit for controlling the first MOS transistor configured to supply a first current to the gate of the first MOS transistor only when the voltage is smaller than a first threshold and draw a second current from the gate of the first MOS transistor only when the voltage is higher than a second threshold, the second threshold being higher than the first threshold.

    Abstract: An electronic device includes a first layer with an antenna and a second metal layer that extends over the entire first layer. The second metal layer includes at least one laterally-closed cavity that is located vertically above the antenna. The cavity is filled, at least in part, by a resin material. A first plate supporting a second metal plate extends over the cavity with the second metal plate positioned vertically above the antenna. The first metal plate may be supported by a ledge within the cavity. Alternatively, the second metal plate is embedded in the resin filling the cavity, with the second metal plate positioned vertically above the antenna.

    Abstract: In an embodiment a method includes modifying or suppressing one or more data values of a non-volatile memory, wherein the one or more data values are stored in a first sector of the non-volatile memory, wherein the first sector is designated as a current sector by one or more selection values stored in the non-volatile memory, wherein modifying or suppressing comprises writing the one or more data values into a second sector of the non-volatile memory, and wherein the second sector is designated as an alternate sector by the one or more selection values.
