Principle of MCU
       Single-chip is an integrated on a singlechip puter system. Even though most of his features in a smallchip, but it has a need plete the majority ponents: CPU,memory, internal and external bus system, most will have the Core. At the sametime, such as munication interfaces, timers, real-time clock andother peripheral equipment. And now the most powerful single-chip putersystem can even voice, image, networking, input and plex systemintegration on a single chip. 
       Also known as single-chip MCU(Microcontroller), because it was first used in the field of industrialcontrol. Only by the single-chip CPU chip developed from the dedicatedprocessor. The design concept is the first by a large number of peripherals andCPU in a single chip, puter system so that smaller, more easilyintegrated into plex and demanding on the volume control devices. INTELthe Z80 is one of the first design in accordance with the idea of theprocessor, From then on, the MCU and the development of a dedicated processorparted ways. 
      Early single-chip 8-bit or all of the of the most essful is INTEL's 8031, because the performance of a simpleand reliable access to a lot of good praise. Since then in 8031 to develop asingle-chip puter system MCS51 series.
