Patent ID: 7829983

Claim:
A semiconductor device comprising: a semiconductor element having plural pads, the plural pads being connected to plural function terminals in a lead frame of an external package via conductive wires, the plural pads being arranged in two lines along the periphery of the semiconductor element, wherein pads in a first line of the two lines of the plural pads which are arranged along the periphery of the semiconductor element are arranged proximate to each other, and pads in a second line of the two lines of the plural pads which are arranged along the periphery of the semiconductor element are arranged proximate to each other, the semiconductor element has positions where an arrangement order of the plural pads in one direction along the periphery differs from an arrangement order of the plural function terminals in the lead frame of the external package, and IO circuit units are connected to the pads in the first line of the two lines of the plural pads and are connected to the pads in the second line of the two lines of the plural pads, each IO circuit unit of the IO circuit units connected to one pad of the pads in the first line of the two lines of the plural pads or one pad of the pads in the second line of the two lines of the plural pads, and the semiconductor element has positions where an arrangement order of the IO circuit units in one direction along the periphery differs from an arrangement order of the plural function terminals in the lead frame of the external package.
