Abstract: A system includes a multi-conductor bus, a master device coupled to the multi-conductor bus, and at least one slave device coupled to the multi-conductor bus. The multi-conductor bus has a clock line and a data line. The master device is arranged to transmit an address configuration sequence, and the at least one slave device is arranged to configurably determine its own address based on at least one portion of the address configuration sequence. The at least one slave device has a physical address configuration input coupled to either a fixed voltage potential or a changing voltage potential. The at least one slave device is arranged with a first address during a pre-initialization state and arranged with a second address during a post-initialization state. During the post-initialization state, the first address and the second address are a same address when the address configuration sequence represents the first address and the first address and the second address are different addresses when the address configuration sequence does not represent the first address.

Abstract: A method for compensating non-linearities of a read signal generated by a variable-capacitance inertial sensor including a first fixed electrode and a second fixed electrode and a mobile electrode, which is spatially arranged between the first and second fixed electrodes and is capacitively coupled to the first and second fixed electrodes, said method comprising the steps of: acquiring the read signal; identifying a first linear component and at least one first nonlinear component of the read signal; a generating a compensated output signal by subtracting the first nonlinear component from the read signal.

Abstract: A signal interface has a compression unit and a data memory. The compression unit is configured to input an input datum from signal data generated by at least one sensor and further configured to identify the presence or absence of at least one repetition condition in the input datum. If the presence of the at least one repetition condition of the input datum is identified, the compression unit encodes the input datum in a compressed way to generate a compressed datum and saves the compressed datum in the data memory. If the presence of the at least one repetition condition of the input datum is not identified, the compression unit saves the uncompressed input datum in the data memory.

Abstract: A device includes sensing circuitry, compression circuitry, and a memory. The sensing circuitry, in operation, generates sensor data. The compression circuitry is coupled to the sensing circuitry, and, in operation, determines environmental contexts based on variation rates of sensor data and compresses sensor data based on determined environmental contexts. The compressed data is stored in the memory.

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.

Abstract: An integrated data concentrator, so-called “sensor hub”, for a multi-sensor MEMS system, implements: a first interface module, for interfacing, in a normal operating mode, with a microprocessor through a first communication bus; and a second interface module, for interfacing, in the normal operating mode, with a plurality of sensors through a second communication bus; the sensor hub further implements a pass-through operating mode, distinct from the normal operating mode, in which it sets the microprocessor in direct communication with the sensors, through the first communication bus and the second communication bus. In particular, the sensor hub implements the direct pass-through operating mode in a totally digital manner.

Abstract: A plurality of sensors provide respective output data rates, with a first sensor that has a highest output data rate, while one or more other sensors have output data rates that are submultiples of the aforesaid highest output data rate. The data signals coming from the sensors are stored in a memory, e.g., a FIFO memory, by storing the data signals of the first sensor at the aforesaid highest output data rate, accompanying storage of the data signals coming from said first sensor with storage of the data signals coming from the sensors as supplied by said other sensors at the aforesaid submultiple output data rates, so that the data signals are stored in the memory according to a repeated pattern that is common to the various sensors.
