Abstract: PROBLEM TO BE SOLVED: To prevent an improper operation resulted from a voltage drop compensation level excessively set high due to an improper instruction or firmware error. SOLUTION: This microprocessor power source system is provided with a programmable power source 30 for supplying a power to a microprocessor, a programmable voltage drop detector 20 connected with the programmable power source for detecting a case that an operating voltage is made lower than a voltage drop reference voltage, and for providing a voltage drop signal output, and a control unit 40 connected with the programmable power source and the programmable voltage drop detector for setting the operating voltage and the voltage drop reference voltage.
