PROBLEM TO BE SOLVED: To reduce an unused area or a wiring area without largely changing the preliminarily designed layout of a semiconductor device at the time of adding or intensifying functions to a semiconductor device. SOLUTION: In a semiconductor device 100A, a wiring area 102 is surrounded by an extended block 103 of a second semiconductor area, and completely interposed by a block 101 and the extended block 103. A plurality of wirings 104 for connecting a CPU 201c in the block 101 to an ROM 301, RAM 302, and A/D converter 303 in the extended block 103 are formed across the wiring area 102 only at a position 204 between adjacent pads 102a.
