The design AT89S51 microcontroller core chip, and the Model 1602 hungry for a digital LCD clock electronic circuit. AT89S51 SCM is a VLSI chip, which integrates CPU, Memory (RAM / ROM), I / O interface, timer / counter, serial communication interface circuit. With a high degree of integration, small size, high reliability and control functions, low power consumption characteristics. Model for the 1602 character LCD with micro-power consumption, small size, content rich, Ultra-thin and light many advantages, in a pocket-type instruments and low-power application system, which is increasingly widely used.
