Products including the technology application of the single chip microprocessor sets already entered every family. As one application of the single chip microprocessor technology, the time controller has been applied in the daily life, the industry situation and military field. This article introduced mainly the design process of the time controller composed by the single chip microprocessor. As the main control component, the single chip microprocessor is the core of the device and it plays the main control action. The clock chip provides a digital clock for the device and helps to realize the function of the timing control. The liquid crystal display is the carrier for the device system demonstrating. The keys use free standing structure. They mainly use as the timing and fixed time and use also as function choice. The control output simulates machine's opening and stops by relay's movement and the light emitter diode. This article has showed the process of the hardware manufacture, the software design and debugging. The function of the time controller is realized finally. KEY WORDS: single chip microprocessor, the clock chip, the liquid crystal display, timing controller
