Abstract

A tire pressure sensor for motor vehicles, includes a housing, which accommodates an integrated circuit (sensor IC), having a microcontroller and a pressure sensor. The microcontroller transfers pressure measurement values to a separate receiver device 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. A power supply is disposed in the housing, and coupled to the sensor IC which 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. The auxiliary memory module can be activated via the microcontroller, in order to copy a selected data packet into the internal memory. The auxiliary memory module is coupled to the microcontroller of the sensor IC by a serial data interface.
