Abstract
A plurality of bypass capacitors are associated with a plurality of circuit blocks involved in a microcomputer. Each bypass capacitor is disposed between a power input terminal of a corresponding circuit block and a ground line. The circuit blocks are arrayed with respect to a power supply terminal in order of the noise level at the power input terminals of respective circuit blocks, so that a circuit block having a lower noise level is located near the power supply terminal while a circuit block having a higher noise level is located far from the power supply terminal.
