Introduced single-chip Single-chip is an integrated on a single chip a complete computer system. Even though most of his features in a small chip, but it has a need to complete the majority of computer components: CPU, memory, internal and external bus system, most will have the Core. At the same time, such as integrated communication interfaces, timers, real-time clock and other peripheral equipment. And now the most powerful single-chip microcomputer system can even voice, image, networking, input and output complex system integration on a single chip.  Single-chip and computer use is also similar to the module, such as CPU, memory, parallel bus, as well as the role and the same hard disk memory, is it different from the performance of these components are relatively weak in our home computer a lot, but the price is low, there is generally no more than 10 yuan you can use it to make some control for a class of electrical work is not very complex is sufficient. We are using automatic drum washing machines, smoke hood, VCD and so on inside the home appliances can see its shadow! It is mainly as part of the core components of the control. Single-chip widely used in instruments and meters, household appliances, medical equipment, aerospace, specialized equipment and the intelligent management in areas such as process control, generally can be divided into the following areas: 1. In the smart application of instrumentation  Single-chip with small size, low power consumption, control, and expansion flexibility, miniaturization and ease of use, widely used in instrumentation, the combination of different types of sensors, can be realized, such as voltage, power, frequency, humidity, temperature, flow, speed, thickness, angle, length, hardness, element, measurement of physical pressure. SCM makes use of digital instrumentation, intelligence, miniaturization and functional than the use of electronic or digital circuitry even stronger. For example, precision measure
