Abstract

Disclosed herein is a configuration for ensuring sufficient power supply ability and ESD protection capability for I/O cells in a semiconductor integrated circuit device, without increasing its circuit area. In two I/O cell rows, a pair of I/O cells for supplying a power supply potential or ground potential are connected together via a common power supply interconnect. The I/O cells are arranged so as to overlap with each other in a first direction in which the I/O cells are arranged. The common power supply interconnect extends in a second direction perpendicular to the first direction, and is connected to first pads that are located closest in the first direction to the common power supply interconnect.
