1. An integrated circuit with data communication stability in a noise environment that is provided in a control target device that includes at least one input section through which a signal is input from a user, at least one output section through which information is output in a predetermined form, and a microcontroller unit (MCU), independently of the microcontroller unit (MCU), and communicates with the microcontroller unit to control, on the basis of the input signal generated from the at least one input section, output driving of the output section corresponding thereto, the integrated circuit comprising:
a serial interface that includes an Rx pin for receiving a data signal from the microcontroller unit by forming a signal reception line with respect to the microcontroller unit and a Tx pin for transmitting a data signal to the microcontroller unit by forming a signal transmission line with respect to the microcontroller unit, to provide a universal asynchronous receiver/transmitter (UART) communication protocol with respect to the microcontroller unit; and
a control logic that controls transmission of a second data signal including an analysis area corresponding to a plurality of consecutive bits indicating information obtained by analyzing a bit structure of a first data signal received from the microcontroller unit to the serial interface through the Rx pin, to the microcontroller unit from the serial interface through the Tx pin for feedback.
