ABSTRACT:
A semiconductor power supplying apparatus driven by a power source includes at 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 power from the power source as needed to supply at least two driven circuits with electric power in accordance with voltages that the driven circuits need. A driven circuit power supplying condition signal generating device is provided so as to generate a driven circuit power supplying condition signal for determining a power supplying condition of all of the at least two driven circuits. A power supplying control signal generation circuit is also provided so as to generate a power supplying control signal for controlling operation of the power supplying circuit. The power supplying control signal is generated from the driven circuit power supplying condition signal and determines an order of supplying power to the at least two driven circuits so that the at least two driven circuits can receive dependent power supplying.
