ABSTRACT:
A microcomputer includes a CPU for processing data, a memory for storing a program for operating the CPU, an input circuit for detecting an input signal exceeding a threshold voltage that lies outside a range from zero volts to a power supply voltage and for supplying a detected input signal exceeding the threshold voltage to the CPU and an output circuit for outputting from the microcomputer a signal output by the CPU. The input circuit reduces power consumption and may include a differential circuit having a pair of transistors with different electrical characteristics, eliminating the need to establish a reference voltage with resistors or other components.
