Abstract: A barometric-pressure-sensor device (20), in particular for a portable electronic device (50), is provided with a pressure sensor (1) of a MEMS type designed to supply a barometric-pressure measurement, and with a processing circuit (22, 23) coupled to the pressure sensor (1) and designed to supply an altitude measurement as a function of the barometric-pressure measurement. The pressure sensor (1) and the processing circuit (22, 23) are integrated in a single chip (20c), and the processing circuit (22, 23) is a dedicated circuit of a purely hardware type. The processing circuit (22, 23) executes altimeter-setting operations, through a plurality of reference registers (27-29) containing respective pressure references.
