ABSTRACT:
A gate array chip is supplied with an operation voltage of 5V. A logic circuit formed of gate arrays in a chip is operated on an operation voltage of 3.3V. The potential of 3.3V is derived by lowering the potential of 5V by use of a voltage lowering circuit disposed in the chip. A level shifter and a converter are disposed in an I/O peripheral circuit to shift the signal level by use of the chip external signal and chip internal signal so that a signal of 5V amplitude can be input or output.
