Abstract: PURPOSE: A remote control key data interface device and an interface method of a car navigation system are provided to prevent the excess loading from being applied to a microcomputer, thereby improving the performance of the microcomputer. CONSTITUTION: A data recognizer(100) decides whether a serial input data of a certain bit is key data or not, and outputs a corresponding driving signal. A data detection latch(200) driven by the driving signal saves the serial input data in parallel mode, and passes the last bit of the serial input data. A key process completer(300) driven by the driving signal counts a scroll input data per a certain time, and outputs a corresponding count clock. An output demander(400) receives the last bit of the serial input data to generate an output demand interrupt at a falling edge, and receives the count clock of the key process completer to output a scroll interrupt. A microprocessor(500) accesses to the serial input data saved in parallel mode when the interrupt of the output demand is started, and completes the scroll action when the scroll interrupt of the output demand is stopped. After the serial key data transmitted from a remote control is converted to the parallel mode signal, the microcomputer outputs the converted serial key data, and also the microcomputer accurately recognizes the completion point of the scroll key data. Therefore, it is possible to eliminate the parallel conversion action of the serial key data and the counting action of the completion point.
