Abstract
The semiconductor integrated circuit incudes an input circuit which receives a signal, an internal circuit which applies a predetermined function to the received signal, and an output circuit which outputs the signal applied with the predetermined function. An external power supply voltage VDD and an IO power supply voltage VDDQ which is lower than the voltage VDD are supplied to the semiconductor integrated circuit. A voltage VIO obtained by decreasing the external power supply voltage VDD is supplied to the input circuit. The IO power supply voltage VDDQ is supplied to the output circuit.
Claims11
A semiconductor integrated circuit comprising:
- an input circuit that receives a signal;
