This paper studies the design and implementation of digital clock system based on digital display. The system has time to set up and display, alarm clock, timer function, MSP430 microcontroller as the core system of low power digital clock system based on MCU and MSP430. System with digital tube display, with keys to provide a friendly user interface, simple operation, the digital clock can long-term, continuous, reliable and stable work at the same time, also has the characteristics of small volume and low power consumption, easy to carry, easy to use. The system software includes the design of microcontroller programming. SCM software programming to achieve the main button, digital display, clock, alarm clock, timer module.   In the design of the full use of internal resources of the microcontroller, involves the keyboard control, digital display, interrupt system, timer/counter and serial communication etc
