Patent ID: 8502551

Claim:
An electronic component comprising a plurality of terminals to be connected to a mounting surface of a substrate through soldering; said electronic component comprising: a transmitting and receiving unit for transmitting and receiving information to and from an external terminal; and a detection controller for starting inspection processing in a state where the plurality of terminals is connected to the mounting surface, in response to the transmitting and receiving unit having received an inspection start information from the external terminal and causing the transmitter and the receiver to transmit an inspection result to the external terminal; wherein the plurality of terminals comprises a functional terminal to be connected to another device, and a redundant terminal not connected to the other device, and the redundant terminal comprises an inspection terminal that is switchable to be an input terminal either with a pull-up resistor or a pull-down resistor; and the detection controller, in the inspection processing, switches the inspection terminal over to be an input terminal either with a pull-up resistor or a pull-down resistor so that a predetermined voltage is applied to the inspection terminal, detects the input voltage of the inspection terminal, and transmits detected input voltage as an inspection result to the external terminal.
