Abstract: The system-on-chip includes at least one microprocessor domain including a microprocessor and at least one resource; and a resource isolation system including a filtering circuit for each resource and configured to detect a security, privilege and compartmentalization access rights violation for the resource, by transactions arriving at the resource. The filtering circuit is configured, in the event of a violation of at least one access right to the resource by a transaction, to generate a first error signal representative of the violated access right to the resource, and a second error signal representative of at least one access right of this transaction.

Abstract: A method is for detecting one or more objects in a detection zone using a time-of-flight sensor. The method includes emitting optical radiation via the emission circuitry of the sensor and subsequently capturing the reflected optical radiation using the reception circuitry. This captured radiation is quantified in terms of photons, and measurement circuitry determines both the amount of these photons and the distance from the sensor to the object(s). An analysis of the photon count, combined with the calculated distance, is used to determine the presence or absence of objects within the detection zone.

Abstract: A circuit can be used for reading out a light sensor. The circuit includes an operational amplifier. A first capacitor has a first electrode coupled to an inverting input of the operational amplifier and a second electrode coupled to a non-inverting output of the operational amplifier. A compensation circuit is coupled between the operational amplifier and the first capacitor. A preset circuit has an input coupled to a first voltage node and an output coupled to the first capacitor. The first voltage node configured to carry a first voltage equal to a preset voltage multiplied by a coefficient.

Abstract: A circuit monitors a first voltage delivered by a battery. The monitored first voltage is compared with a second voltage. When the comparator detects that the first voltage is smaller than the second voltage, a counter starts counting. If the value of the counter during said counting exceeds a limiting value, an interruption signal is generated to control an operating mode of an electronic device power by said battery.

Abstract: An ambient light sensor includes pixels arranged in an array. Each pixel includes a doped insulated well of a first type, a pinned photodiode in the well, a doped region of a second type arranged in the well, a transfer gate coupling the photodiode to said region, and a first circuit applying a first or second potential to the well. A successive approximation analog-to-digital converter of the sensor has a node connected to the doped regions of the pixels, a switch applying a third potential to the node, a comparator coupled to the node, and a second circuit receiving an output of the comparator and controlling the first circuits to selectively apply the first and second potentials. A sensor control circuit controls the gates and the first switch.

Abstract: A first terminal receives a first DC voltage. A switch selectively couples the first terminal to a second terminal providing an output. A control circuit selectively actuates the switch in response to a comparison of the first DC voltage to a second DC voltage. A low-dropout (LDO) linear voltage regulator, connected between the first and third terminals, operates to provide the second DC voltage from the first DC voltage.
