Title:
SEMICONDUCTOR INTEGRATED CIRCUIT
Document Type and Number:
Japanese Patent JP2005086108
Kind Code:
A
Abstract:

To provide a semiconductor integrated circuit which can easily carry out a production test and can reduce a production test man-labor.

As an output voltage of a VDC(voltage down converter) circuit 20 is A/D converted by a A/D converter 22, the output voltage VDCout of the VDC circuit 20 can be observed as a digital quantity and the measurement becomes easy. Preferably, a chip size can be reduced by decreasing the number of terminals 6. Moreover, the terminals 6 used to output the voltage VDCout can be used for other use.
