Abstract: A diagnostic circuit is used for detecting the load status of an audio amplifier. The audio amplifier includes two output terminals for connection to a speaker. The diagnostic circuit may include a first circuit, which configured to generate a first signal indicating whether a signal provided via the two output terminals comprises an audio signal. A second circuit can be configured to detect a first measurement signal being indicative for the output current provided via the two output terminals, and to compare the first measurement signal with at least one threshold in order to generate a second signal indicating whether the output current has a low current amplitude profile or a high current amplitude profile. A third circuit can be configured to generate a diagnostic signal as a function of the first and the second signal.

Abstract: A pressure sensor with double measuring scale includes: a flexible body designed to undergo deflection as a function of a the pressure; piezoresistive transducers for detecting the deflection; a first focusing region designed to concentrate, during a first operating condition, a first value of the pressure in a first portion of the flexible body so as to generate a deflection of the first portion of the flexible body; and a second focusing region designed to concentrate, during a second operating condition, a second value of said pressure in a second portion of the flexible body so as to generate a deflection of the second portion of the flexible body. The piezoresistive transducers correlate the deflection of the first portion of the flexible body to the first pressure value and the deflection of the second portion of the flexible body to the second pressure value.

Abstract: A cryptographic method includes providing memory locations for storing encrypted data. The memory locations have respective addresses and are accessible via a communication bus. The method includes receiving over the communication bus access requests to the memory locations, wherein the access requests include burst requests for access to respective sets of the memory locations starting from respective start addresses, and calculating as a function of the start addresses encryption/decryption cryptographic masks based on cryptographic keys. Plain text data is received for encryption and the method includes applying the cryptographic masks to the plain text data to obtain therefrom encrypted data, and including the encrypted data into output data for transmission over the communication bus.

Abstract: A phase change memory includes an L-shaped resistive element having a first part that extends between a layer of phase change material and an upper end of a conductive via and a second part that rests at least partially on the upper end of the conductive via and may further extend beyond a peripheral edge of the conductive via. The upper part of the conductive via is surrounded by an insulating material that is not likely to adversely react with the metal material of the resistive element.

Abstract: A signal processing chain, such as an audio chain, produces an analog output signal from a digital input signal. The signal processing chain is operated by generating a first flag signal for the analog output signal and one or more second flag signals for the digital input signal. Each flag signal assumes a first level or a second level and is set to the first level when a signal from which the flag is generated has a value within an amplitude window. An amount the first flag signal for the analog output signal and the second flag signal for the digital input signal match each other may be calculated for issuing an alert flag which indicates an impaired operation of the signal processing chain.

Abstract: A circuit includes a first node configured to receive a reset signal. A reset drive stage drives a reset node. The reset drive stage is coupled to the first node via a reset signal path to propagate the reset signal to the reset drive stage. The reset drive stage is activated as a result of assertion of a reset actuation state of the reset signal. A sensing node is coupled to the reset node via a signal sensing path. The sensing node is sensitive to a signal level of the reset node reaching a reset threshold. A reset signal hold circuit block is coupled to the first node and is configured to receive a reset command signal and assert the reset actuation state of the reset signal at the first node as a result of the reset command signal received.
