Summary:To provide a semiconductor integrated circuit device capable of notifying a failure to a rear-step circuit and reducing a restriction against the rear-step circuit.SOLUTION: A semiconductor integrated circuit device (1) includes: signal processing circuits (13, 14, 15, and 18) that is constructed so as to process a signal to be received; a failure detection circuit (16) that is constructed so as to detect a failure in the semiconductor integrated circuit device; and an output terminal (T3). In the case where the failure is not detected by the failure detection circuit, an output signal of the signal processing circuit is output from the output terminal to an external part. In the case where the failure is detected by the failure detection circuit, a command for notifying a content of the failure is output from the output terminal to the external part.SELECTED DRAWING: Figure 1 【課題】後段回路に故障を通知することができ、後段回路に対する制約を少なくすることができる半導体集積回路装置を提供する。【解決手段】半導体集積回路装置(1)は、受け取った信号を処理するように構成された信号処理回路(13、14、15、18)と、前記半導体集積回路装置内の故障を検出するように構成された故障検出回路(16)と、出力端子(T3)と、を有する。前記故障検出回路によって前記故障が検出されていない場合、前記出力端子から前記信号処理回路の出力信号が外部出力される。前記故障検出回路によって前記故障が検出されている場合、前記出力端子から前記故障の内容を通知するコマンドが外部出力される。【選択図】図1
