1、Technology Development and Application of Single-chipAbstract: Since the advent of single chip since the compact because of its flexibility, low cost, control, and ease of production, such as advantages, in all areas of society have been widely used. In this paper, single-chip technology development
2、 and application are discussed.Key words: single-chip application1 single-chip technology The so-called single-chip microcomputer (m1crocontroller) is defined as an integrated chip, integrated microprocessor (CPU), memory, basic I / O interfaces and timer / counter, communications components, that i
3、s, in a one chip micro-computer basic functions. In 1970 after the successful development of micro-computer, with the emergence of a single chip (ie, single-chip micro-computer). Intel Corporation in 1971 the U.S. production of four single-chip 4004 and 1972, the embryonic form of the production of
4、8-bit single-chip 8008, in particular the 1976 MCS-48 single-chip has been available, in a short span of 20 years, experienced a replacement of four, the speed of its development approximately every two or three more next-generation, integrated double double feature. The speed of its development, ap
5、plication scope, has reached alarming proportions, it has penetrated into the production and all areas of life. Although many varieties of single-chip, but when one of the most typical of a number of Intels MCS-51 series single chip. MCS-51 is the MCS-48 based on the in the early 80s developed, alth
6、ough it is still 8-bit microcontroller, but there are a lot of enhanced features. As a result of PHILIPS, ATMEL, WELBORD, LG and other IC manufacturers nearly home births are the main product 51 series compatible with a wide variety, compatibility, and informative features such as hardware and softw
7、are. Therefore, MCS-51 Application of a very wide range of MCS-48 become the most important single-chip variety. MCS-51 until now is still the mainstream models of single-chip microcomputer. Intel in particular domestic MCS-51 series of the most widely used single-chip microcomputer. 8-bit single-ch
8、ip microcomputer as a result of the high cost performance, it is estimated that nearly a decade, the 8-bit single-chip MCU will continue to be the mainstream models.2 single-chip technology With the development of computer technology and control systems in a wide range of applications, as well as eq
9、uipment to small and intelligent development, as one of the single-chip high-tech for its small size, powerful, low cost, and other advantages of the use of flexible, show a strong vitality. It is generally better compared to the integrated circuit of anti-interference ability, the environmental tem
10、perature and humidity have better adaptability, can be stable under the conditions in the industrial work. And single-chip widely used in a variety of instruments and meters, so that intelligent instrumentation and improve their measurement speed and measurement accuracy, to strengthen control funct
11、ions. Such as the MCS-51 series single-chip microcomputer to control the state of auto-navigation of the ship logger, tobacco moisture tester, Intelligent Ultrasonic Thickness Gauge and so on. Also widely used in single-chip real-time control system, for example, a variety of industrial furnace temp
12、erature, acidity, chemical composition measurement and control. Measurement technology, automation technology and single-chip technology, and give full play to its data processing capabilities and real-time control functions, allowing the system to work at its best, improve the production efficiency
13、 and product quality. From the aerospace, petroleum geology, mining metallurgical, machinery and electronics, light industry, textile industry and other distribution systems and intelligent control and electromechanical integration equipment and products, to the posts and telecommunications, househo
14、ld equipment and instruments, single-chip microcomputer has played an enormous role in . Its applications can be broadly divided into the following aspects: electromechanical integration equipment, the control core. Mechatronics is the direction of the development of machinery and equipment. Promote
15、 the emergence of single-chip integration of mechanical and electrical technology, mechanical and electrical products as the controller, and give full play to the advantages of its own, greatly enhanced the function of the machine, raise the machine automation, intelligent. The most typical mechanic

Large-scale data acquisition systems, data acquisition synchronization requirements and better real-time. As the use of single-chip front-end acquisition unit, collected by the host computer to issue commands, and then collected the data one by one to the main computer for processing. For example, som
