UNIVERSAL TIRE PRESSURE SENSOR

A tire pressure sensor for motor vehicles, with a housing (1), an integrated circuit (sensor IC) (2) accommodated in the housing (1), wherein the sensor IC has a microcontroller (3) and a pressure sensor (4). Means (6, 9; 7, 10) for wireless communication are arranged in the housing (1), which are coupled with the microcontroller (3) in order to transmit pressure measurement values detected by means of the pressure sensor (4) to a remote receiving device. The sensor IC (2) has an internal memory in which executable instructions and data can be stored, which upon execution effect the acquisition and transmission of pressure measurement data. The sensor IC (2) is coupled with an additional memory module (15) arranged in the housing (1), wherein a plurality of different data packets with respective instructions or data are stored in the memory module. The additional memory module (15) is controllable by the microcontroller (3) in order to copy a selected data packet into the internal memory, and the microcontroller (3) controls the power supply of the additional memory module (15) such that the additional memory is switchable into an energy-saving mode.
