(Single-Chip Microcomputer), is a set of CPU, RAM, ROM, from time to time, the count in one interface and a variety of microcontrollers. His small size, low cost, feature strong, smart widely used in industrial automation products and on. This article has designed a single chip at the core AT89C52 and several new types of chips composed of multi-function digital clock. Constitute a single chip by the main part of the major information processing, to receive operating instructions to form a variety of external control signals, the use of the simplest circuit, the cheapest a perfect circuit chip. The graduation project through its study and application in order to reach the study, design, development software and hardware.
