Abstract: A method of interfacing a LC sensor with a control unit is provided. The control unit may include first and second contacts, where the LC sensor is connected between the first and the second contact. A capacitor is connected between the first contact and a ground. To start the oscillation of the LC sensor, the method may include during a first phase, connecting the first contact to a supply voltage and placing the second contact in a high impedance state such that the capacitor is charged through the supply voltage. During a second phase, the first contact may be placed in a high impedance state, and the second contact connected to the ground such that the capacitor transfers charge towards the LC sensor. During a third phase, the first contact and the second contact may be placed in a high impedance state so the LC sensor is able to oscillate.

Abstract: A method of interfacing an LC sensor with a control unit is described. The control unit may include first and second contacts, and the LC sensor may be connected between the first and second contacts. The method may include starting the oscillation of the LC sensor, and monitoring the voltage at the second contact, in which the voltage at the second contact corresponds to the sum of the voltage at the first contact and the voltage at the LC sensor. The voltage at the first contact may be varied such that the voltage at the second contact does not exceed an upper voltage threshold and does not fall below a lower voltage threshold.

Abstract: In an embodiment, access transactions of at least one module of a system such as a System-on-Chip (SoC) to one of a plurality of target modules, such as memories, are managed by assigning transactions identifiers subjected to a consistency check. If an input identifier to the check has already been issued for the same given target module, to the related identifier/given target module pair the same input identifier is assigned as a consistent output identifier. If, on the contrary, said input identifier to the check has not been already issued or has already been issued for a target module different from the considered one, to the related identifier/given target module pair a new identifier, different from the input identifier, is assigned as a consistent output identifier.
