Vehicular electronic control apparatus

摘要

A core integrated circuit device has a microprocessor. A first ancillary integrated circuit device has an indirect parallel input circuit that receives low-speed digital signals parallel, and the first ancillary integrated circuit device outputs the received digital signals serially to the core integrated circuit device. A second ancillary integrated circuit device has a multi-channel A/D converter that receives analog signals parallel and converts those into digital signals, and the second ancillary integrated circuit device outputs the digital signals serially to the core integrated circuit device. The core integrated circuit device generates control signals based on the received signals and outputs the control signals to control object devices.
