Abstract
A semiconductor device is capable of detecting a power supply voltage abnormality without degrading the performance of internal circuits. The semiconductor device includes a plurality of power supply inspection circuits and a result storage register. The power supply inspection circuits detect a power supply voltage abnormality in each pad that couples an internal wiring disposed in the semiconductor device to another part disposed outside of the semiconductor device. The result storage register stores inspection results indicated by result signals output from the power supply inspection circuits.
