Abstract: In our daily life, the electronic clock is closely related to the electronic clock which will be used in many places. In addition to a dedicated clock, timing licenses, there are many applications which often with real-time clock display, such as a variety of intelligent instrumentation, industrial process control systems and home appliances. There are many ways to realize the Electronic clock, through the front of learning our SCM basic theory and related knowledge, here, the microcontroller-based control chip design a simple single-chip electronic clock. With the development of computer penetration in the social field and LSI in recent years, the using of microcontroller applications is constantly go deeper, because it has the features of a small size, low power consumption, cheap, reliable, easy to use. Therefore it is particularly suitable for the control of the system, more and more widely used in automatic control, Intelligent instruments, data acquisition, and military products and home appliances, SCM often used as a core
