摘要：A semiconductor power supplying apparatus driven by a power source includesat least two driven circuits for performing prescribed data processing when electric

power is supplied. An electric power supplying circuit is provided so as to convert powerfrom the power source as needed to supply at least two driven circuits with electricpower in accordance with voltages that the driven circuits need. A driven circuit powersupplying condition signal generating device is provided so as to generate a driven circuitpower supplying condition signal for determining a power supplying condition of all ofthe at least two driven circuits. A power supplying control signal generation circuit is alsoprovided so as to generate a power supplying control signal for controlling operation ofthe power supplying circuit. The power supplying control signal is generated from thedriven circuit power supplying condition signal and determines an order of supplyingpower to the at least two driven circuits so that the at least two driven circuits can receivedependent power supplying.
