Abstract
A semiconductor sensor device which has a decreased number of terminals, which is cheaply and compactly constructed and which contains a trimming circuit. A power source voltage and a clock signal having a voltage level greater than the power source voltage are input to a terminal 31. A logic circuit 22 starts operating at one voltage level of a terminal 33 and temporarily stores serial digital signals that are input through a terminal 32 in response to clock signals as parallel trimming data. A gauge circuit 11 operates based on the stored trimming data, and the gauge output is sent to the terminal 32. With another voltage level from the terminal 33, the logic circuit 22 trims a fuse memory circuit 23 based on the stored trimming data. At a further voltage level from the terminal 33, the gauge circuit 11 is operated based on the data in the fuse memory circuit 23 that is trimmed, and an output signal thereof is sent to the terminal 32.
