ABSTRACT:
An intermediate voltage generating circuit for generating a voltage lying between an external power supply voltage and a ground voltage, and two voltage limiter circuits for generating internal power supply voltages and stabilized with this intermediate voltage as a reference are provided in a semiconductor integrated circuit. Even if the external power supply voltage or the ground voltage fluctuates, no disagreement is produced between a logical threshold of a circuit operating on the external power supply voltage and a logical threshold of a circuit operating on the internal power supply voltage.
