Abstract

PURPOSE:To improve the mass productivity by modifying a wiring pattern in accordance with applying voltage to raise or reduce the voltage and thus forming a monolithic semiconductor circuit responsive to the voltage specification. CONSTITUTION:When a battery E is low voltage, a terminal T1 is connected to the voltage supply circuit terminal T2 of a voltage rising circuit 4 and to the voltage supply circuit terminal T7 of an information processing circuit 2, and the raised voltage output terminal T3 is connected to the voltage supply circuit terminal T6 of a display circuit 3 as indicated by broken lines. When the battery E is high voltage, the terminal T1 is connected to the voltage supply circuit terminal T4 of a voltage falling circuit 5 and to the terminal T6, and the dropped voltage output terminal T5 is connected to the terminal T7 instead of the connection designated by the broken lines. Thus, the predetermined wiring pattern is modified, thereby forming all the voltage rising or falling circuit, and a necessary power voltage can be obtained.
