Single-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.
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 MCU Systems. SCM systems based on
this system until now is 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
and enter the mainstream market. The traditional 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 [1] model only
10 dollars.Modern SCM systems are no longer only i
