Single-chip 1. The definition ofa single-chip Single-chip is an integrated ona single chip puter system .Even though most of his features ina small chip , but it has a need plete the majority ponents : CPU , memory , internal and external bus system , most will have the the same time , such as munication interfaces , timers , real-time clock and other peripheral now the most powerful single-chip puter system can even voice , image , networking , input and plex system integration ona single chip. Also known as single-chip MCU ( Microcontroller ), because it was first used in the field of industrial by the single-chip CPU chip developed from the dedicated processor. The design concept is the first bya large number of peripherals and CPU ina single chip , puter system so that smaller , more easily integrated into plex and demanding on the volume control the Z80 is one of the first design in accordance with the idea of the processor , From then on, the MCU and the development ofa dedicated processor parted ways. Early single-chip 8-bit or all the of the most essful is INTELs 8031 , because the performance ofa simple and reliable access toa lot of good then in 8031to develop a single-chip puter system MCS51 on single-chip puter system of the system is still widely used until the field of indus
