Abstract
An input/output pad part <5> comprises an input protection circuit <51> which is connected to an external terminal <OT>, an output buffer <52> which is connected to the input protection circuit <51>, a TTL input detection circuit <53>, a Schmidt type input detection circuit <54> and a voltage conversion part <55>enabling transfer of signals having different voltage levels between the same and an internal circuit. Thus provided is a microcomputer employing different power supply voltages for circuits constructing an input/output part and an internal circuit such as a logic part or a memory part, which is capable of transferring signals of different voltage levels between the internal circuit and the circuits constructing the input/output circuit and performing slew rate control.
