  • Processor having an extended operating voltage range
    Patent number: 6446212
    Abstract: A processing unit, preferably a RISC based microcontroller, is coupled to a processing unit voltage regulator. The processing unit voltage regulator is used for controlling an operating voltage of the processing unit. A control unit is coupled to the processing unit voltage regulator and to the processing unit for setting a regulated voltage level for the processing unit voltage regulator. A voltage supply coupled to the control unit and to the processing unit voltage regulator is provided and is used for supplying the operating voltage for the processing unit wherein the operating voltage will have an upper and lower operating voltage level and an voltage supply operating range of approximately two to eighteen volts with relatively little variation in operating current.
