Abstract

A tire pressure sensor for motor vehicles includes a housing accommodating an integrated circuit (sensor IC), wherein the sensor IC has a microcontroller and a pressure sensor. The microcontroller, transfers pressure measurement values acquired by the pressure sensor to a receiver by wireless communication. The sensor IC has an internal memory, in which executable instructions and data can be stored, which, when executed, result in the acquisition and transference of the pressure measurement data. The sensor IC is coupled to an auxiliary memory module disposed in the housing. Numerous different data packets, with respective instructions or data, are stored in the memory module which can be activated via the microcontroller, in order to copy a selected data packet into the internal memory. The microcontroller controls the power supply for the auxiliary memory module such that the auxiliary memory can be switched over to an energy saving mode.
