More Information
Summary:A microprocessor has a control unit with a housing surrounding the control unit. The invention also relates to a chip card having such a microprocessor that is protected against manipulations. At least one sensor indicates ambient states and is connected to the control unit and is provided in a region of the housing of the microprocessor. The control unit is configured in such a way that it can be placed in an inactive state if a measurement signal that indicates a predetermined ambient state is and/or is not fed to the control unit from the sensor.
