【正文】 application. In fact the number of SCM is the world39。 Modern human life used in almost every piece of electronic and mechanical products will be integrated single chip。 Personal puter will have a large number of SCM in the work。 Single chip, also known as singlechip microcontroller, it is not plete a certain logic chips, but to a puter system integrated into a to a microputer, and puter than just the lack of a microcontroller I / O devices. General talk: a chip bees a puter。 SCM and the puter functions internally with similar modules, such as CPU, memory, parallel bus, the same effect as well, and hard disk memory devices, and different is its performance of these ponents were relatively weak many of our home puter, but the price is low , usually not more than 10 yuan you can do with it some control for a class is not very plicated electrical work is enough of。 It is an online realtime control puter, controlline is that the scene is needed is a stronger antijamming ability, low cost, and this is, and offline puter (such as home PC), the main difference。s with the United States developed 74 series, or the 6039。s with a series of successful SCM market, the result will be a drastic change! Just because you are prepared by microputer programs can achieve high intelligence, high efficiency and high reliability! As the microcontroller on the costsensitive, so now the dominant software or the lowest level assembly language, which is the lowest level in addition to more than binary machine code language, and as so low why is the use? Many highlevel language has reached the level of visual programming Why is not it? The reason is simply that there is no home puter as a single chip CPU, not as hard as a mass storage visualization of small highlevel language program which even if only one button, will reach tens of K of size! For the home PC39。 Can be said that the twentieth century across the three power era, that is, the age of electricity, the electronic age and has entered into the puter age. However, this puter, usually refers to the personal puter, referred to as PC. It consists of the host, keyboard, monitor and other ponents. Another type of puter, most people do not know how. This puter is to give all kinds of intelligent machines single chip (also known as microcontroller). As the name suggests, this puter system took only a minimal integrated circuit, can be a simple operation and control。 SCM history： SCM was born in the late 20th century, 70, experienced SCM, MCU, SOC three stages。 the microcontroller (Micro Controller Unit) stage, the main direction of technology development: expanding to meet the embedded applications, the target system requirements for the various peripheral circuits and interface circuits, highlight the object of intelligent involves the areas associated with the object system, theref
