Abstract
A microprocessor power supply system, which features a programmable power supply and a programmable brownout detector with a central control unit that allows for independent, but coordinated, control of operating voltage and brownout reference voltage. The invention prevents improper programming of the operating voltage and the brownout reference voltage levels. The programmable power supply and brownout detector threshold can also be controlled to provide an optimum threshold over a range of operating voltages.
