Structure and function of the MCS-51 series
Structure and function of the MCS-51 series one-chip
computer MCS-51 is a name of a piece of one-chip computer
series which Intel Company produces. This company
introduced 8 top-grade one-chip computers of MCS-51 series
in 1980 after introducing 8 one-chip computers of MCS-48
series in 1976. It belong to a lot of kinds this line of
one-chip computer the chips have,such as 8051, 8031, 8751,
80C51BH, 80C31BH,etc., their basic composition, basic
performance and instruction system are all the same. 8051
daily representatives- 51 serial one-chip computers .
An one-chip computer system is made up of several
following parts: ( 1) One microprocessor of 8 (CPU). ( 2)
At slice data memory RAM (128B/256B),it use not depositting
not can reading /data that write, such as result not middle
of operation, final result and data wanted to show, etc.
( 3) Procedure memory ROM/EPROM (4KB/8KB ), is used to
preserve the procedure , some initial data and form in
slice. But does not take ROM/EPROM within some one-chip
computers, such as 8031 , 8032, 80C ,etc.. ( 4) Four 8 run
side by side I/O interface P0 four P3, each mouth can use
as introduction , may use as exporting too. ( 5) Two timer
/ counter, each timer / counter may set up and count in the
way, used to count to the external incident, can set up
into a timing way too, and can according to count or result
of timing realize the control of the computer. ( 6) Five
cut off cutting off the control system of the source . ( 7)
One all duplexing serial I/O mouth of UART (universal
asynchronous receiver/transmitter (UART) ), is it realize
