In their daily work life fast rhythm, time occupies a crucial position. Maybe people dont care too much, in a variety of daily life and all kinds of social activities, we every hour and moment are watching the change of time. The time of our lives, and the calculation method of time has evolved into a clock and watch. Digital clock is described in this paper has a variety of functions, not only can display the date when the minutes and seconds time, accurate, and measurement of environmental temperature, alarm clock, stopwatch, electronic clock, MP3 player and other functions. Compared to the mechanical clock, because the digital clock is used in the digital circuit technology to realize, when, seconds, has a higher accuracy and stability, and the structure and device of digital clock is more scientific and convenient. This paper mainly introduces the design of multi-function digital clock based on MCU, the hardware circuit consists of the clock module, temperature detecting module, liquid crystal display module, keyboard module, power module, voice module and a reset circuit, software design including alarm clock, stopwatch design, electronic book reading, MP3 player etc.. The design of the digital clock: time date display, minutes and seconds, alarm clock, stopwatch, e-books, MP3 etc.. Combined with the MCU and the multi-function digital clock, not only makes the measurement more accurate and stable time, environmental testing temperature is more simple, convenient, flexible, provides better quality and convenience to our daily life. Therefore, the single chip not o
