The Single-chip Microcomputers
Abstract
: nowadays, almost
nobody are not familiar with the computer.
Exactly,
people’
s life will
not continue without the computer. Now, the
computer is more and
more likely to be
used in an automatic system design to
imit
ate human being’s brain.
This essay will introduce something
about Single-chip Microcomputers.

the Single-chip Microcomputer or MCU

If
you
meet
the
massive

then
the
system
can
be
the
embedded

(such
as

called
the

SCM

Subsequently,
the
MCU embedded applications to meet the
