Single-chip

Abstract：Single chip, also known as single-chip microcontroller, it is not complete a certain logic chips, but to a computer system integrated into a chip. SCM is also known as micro-controller (Microcontroller Unit), commonly used letters of the acronym MCU that it was first used in industrial control.Are 8-bit microcontroller early or4 bits.In fact the number of SCM is the world's largest computer. Modern human life used in almost every piece of electronic and mechanical products will be integrated single chip.

Key words:Single chip;Microcontroller Unit

SCM is also known as micro-controller (Microcontroller Unit), commonly used letters of the acronym MCU that it was first used in industrial control.Only a single chip by the CPU chip developed from a dedicated processor. The first design is by a large number of peripherals and CPU on a chip in the computer system, smaller, more easily integrated into a complex and demanding on the volume control device which. INTEL'sZ80 is the first designed in accordance with this idea processor, then on the development of microcontroller and dedicated processors have parted ways.

Are 8-bit microcontroller early or4 bits. One of the most successful is the INTEL 8031, for a simple, reliable and good performance was a lot of praise. Then developed in 8031 out of MCS51 MCUSystems. SCMsystems based on this system until nowis still widely used. With the increased requirements of industrial control field, began a 16-bit microcontroller, because the cost is not satisfactory but have not been very widely used. After 90 years with the great

development of consumer electronics, microcontroller technology has been a huge increase. With INTEL i960 series, especially the later series of widely used ARM, 32-bit microcontroller quickly replace high-end 16-bit MCU status andenterthemainstream market.Thetraditional 8-bit microcontroller performance have been the rapid increase capacity increase compared to 80 the number of times. Currently, high-end 32-bit microcontroller clocked over 300MHz, the performance catching the mid-90's dedicated processor, while the average model prices fall to one U.S. dollars, the most high-end model only 10 dollars.Modern SCM systems are no longer only in the development and use of bare metal environment, a large number of proprietary embedded operating system is widely used in the full range of SCM. The handheld computers and cell phones as the core processing of high-end microcontroller can even use a dedicated Windows and Linux operating systems.

SCM is more suitable than the specific processor used in embedded systems, so it was up to the application. In fact the number of SCM is the world's
