Abstract
An internal input voltage generating/external output voltage generating circuit is provided within a semiconductor device, a voltage on a pad corresponding to a supply pin terminal is detected to specify the inserted orientation of the semiconductor device based on the detection result and apply a correct voltage to a chip internal circuit. According to the specified direction, one of a plurality of pin terminals located in rotation or line-symmetry is selected to couple the selected terminal to the chip internal circuit. Accordingly, a semiconductor device can be implemented that is never damaged and operates normally even if the device is mounted on a circuit board in any possible orientation which the device can take upon board mounting.
