Abstract: A sensor includes detection circuitry and control circuitry coupled to the detection circuitry. The detection circuitry generates a detection signal indicative of a detected physical quantity. The control circuitry, in operation receives the detection signal and a frequency-indication signal, and generates a trigger signal based on the frequency-indication signal and a set of local reference signals. The sensor generates a digital output signal and a locking signal based on the trigger signal and the detection signal. The generating the digital output signal includes outputting a sample of the digital output signal based on the trigger signal. The locking signal is temporally aligned with the digital output signal.

Abstract: An interface electronic circuit couplable to a first transducer that generates a first analog signal indicative of a first quantity and to a microcontroller unit, the interface electronic circuit including: a first conversion stage, which generates a first digital signal as a function of the first analog signal; a DSP stage, which includes at least one DSP unit and generates a processed signal as a function of the first digital signal; an advanced-processing stage, which detects, by execution of a processing of the processed signal, the occurrence of an target condition regarding the first quantity; and a number of registers, which store values of configuration parameters. The advanced-processing stage writes at least one subset of the registers, after detecting the occurrence of the target condition, so as to vary the values of the configuration parameters stored in the subset of registers.

Abstract: A device includes one or more inertial sensors and fusion circuitry coupled to the one or more inertial sensors. The inertial sensors, in operation, generate inertial sensor data with respect to a plurality of axes of movement. The fusion circuitry, in a polar fusion mode of operation, applies a plurality of polar rotation operations to the generated inertial sensor data to rotate the generated inertial sensor data onto an axis of the plurality of axes of movement. A fused data signal is generated based on a result of the plurality of polar rotation operations. The plurality of inertial sensors may include bone-conduction sensors.

Abstract: A sensor includes an accelerometer, which, in operation, generates accelerometer data, and digital signal processing circuitry. The digital signal processing circuitry, in operation, generates, based on the generated accelerometer data, a value indicative of a cosine of an angle between an acceleration vector associated with current accelerometer data and a reference acceleration vector, compares the generated value indicative of the cosine of the angle between the vector associated with current accelerometer data and the reference acceleration vector with one or more thresholds and generates a tilt signal based on the comparison of the generated value indicative of the cosine of the angle between the vector associated with current accelerometer data and the reference acceleration vector with the one or more thresholds. The tilt signal may be used as an interrupt signal to an application processor.
