Abstract: A connector that is configured to receive a smart card includes: a first contact configured to receive a power supply voltage and corresponding to a first (power supply) contact area of the smart card, a second contact configured to receive a reference voltage and corresponding to contact a second (reference voltage) contact area of the smart card, and a third contact corresponding to a three-state (input/output) contact area of the smart card. A first light-emitting diode having an anode coupled to the third contact and a cathode coupled to the second contact. A second light-emitting diode has a cathode coupled to the third contact and an anode coupled to the first contact. Turning on/off of the first and second light-emitting diode is controlled by the smart card through the signal at the three-state (input/output) contact area.

Abstract: An embodiment DC to DC conversion circuit comprises a DC to DC converter and a regulation circuit. The regulation circuit comprises a comparator configured to detect, during a discharge phase of the DC to DC converter, an overshoot period during which an output voltage of the DC to DC converter exceeds a target voltage, and a timer configured to measure a duration of the overshoot period.

Abstract: System on a chip, comprising several master pieces of equipment, several slave resources, an interconnection circuit coupled between the master pieces of equipment and the slave resources and capable of routing transactions between master pieces of equipment and slave resources. A first particular slave resource cooperates with an element of the system on a chip, for example a clock signal generator, and the element has the same access rights as those of the corresponding first particular slave resource.

Abstract: A method for monitoring an activity of a connected object including a monitoring device, includes: performing, by a measurement stage of the monitoring device, a first periodic measurement of an internal signal representative of an activity of the connected object; performing, by a computation stage of the monitoring device, a first non-cryptographic computation of an activity parameter representative of the activity from the internal signal measured during the first periodic measurement; comparing, by a comparison stage of the monitoring device, between the activity parameter on completion of the first non-cryptographic computation and a range of settings of corresponding to the activity parameter; and triggering, by a control stage of the monitoring device, a safety action in response to a determination that the activity parameter is outside of the range of settings.

Abstract: A method for vehicle parking assistance during a parking maneuver of the vehicle includes detecting an obstacle in a detection space outside the vehicle. Successive measurements are taken of the distance or distances separating the vehicle and the obstacle and the position or positions of the obstacle relative to the vehicle. Depending on the results of the measurements, human speech voice messages are generated that provide parking assistance. The voice messages are broadcasted in the passenger compartment of the vehicle.

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: System, method, and circuitry for generating content for a programmable computing device based on user-selected memory regions. Contiguous regions that share memory access attributes are merged, interleaved contiguous regions that share at least one nested attribute are defined into combined regions, and remaining regions are defined as separate independent regions. A memory protection unit (MPU) region size closest to a size of each defined region is identified. If the start address of each region aligns with the address structure of the MPU region size, then those regions are assigned to MPU regions having the MPU region size; otherwise, another MPU size that aligns with the size of the regions is selected and those regions are assigned to MPU regions having that size. Content is generated to configure settings of MPU regions of the programmable computing device for the merged contiguous regions, the combined region, and the independent regions.

Abstract: In an embodiment a DC to DC conversion circuit includes a DC to DC converter connected to an input path and an output path and a current limiting circuit including a circuit configured to detect when an input or output current of the DC to DC converter exceeds or falls below a current threshold and a controller configured to store a first voltage level of an output voltage of the DC to DC converter in response to the input or output current exceeding the current threshold, to store a second voltage level of the output voltage in response to the input or output current falling below the current threshold and to set a control signal based on the first and second voltage levels.
