from Ekeeda Hello friends in this video
we will study a new chapter called as
microcontroller now before starting a
microcontroller we need to understand
the difference between microcontroller
and micro processor now what is micro
processor that may already know the chip
which is installed in our computer we
called it as what micro processor now if
you see the difference between the micro
processor and micro controller you can
say micro controller can be used for the
online applications whereas micro
processor can be used for the offline
applications so let us see what is micro
controller in detail micro controller
let us see a definition of micro
controller a micro controller is a
complete micro processor system
consisting of micro processor limited
amount of room a Pierrot Ram
input/output port built on single
integrated circuit so you can say a
micro controller has a limited amount of
memory dan fo micro processor and in the
starting of the video we have already
discussed the basic difference between
micro controller and micro processor is
that micro controller can be used for
the online applications whereas micro
processor can be used for the offline
application so our home computer is you
can say it is a micro processor whereas
your ATM machine okay which works for
which works only online you can call it
as what micro controller so what my
definition of micro controller says a
micro controller is a complete micro
processor system but it has the limited
amount of memory into it it has the
limited amount of RAM it has the limited
amount of room EP row and input/output
ports and all they are integrated on the
single IC it is in fact a micro
controller but it is called so because
it is used to perform a control function
as we discussed it is used to perform
what control function so that's why it
is called as micro controller it is more
complex than micro processor because it
consists of many input and output
component
of the microcontrollers our intel 8 0 4
8 and Intel 8:05 and in this topic we
are going to discuss more about in del
h0 fiber micro controller
next is applications of micro controller
or you can say advantages of micro
controller over micro processor so
number one advantage is that it is a low
cost it is low cost than what micro
processor so the cost of micro
controller is less than micro processor
number two we have already studied micro
controller has more input output
component so that's why we called it as
what it is more complex why it is
complex because it has more input/output
component number three it can be used in
many low cost products such as
electronic toys or it can be used in the
microwave ovens or it can be used in the
machines it can be used in the chemical
instrumentation it can be used in the
medical instrumentation and so on it can
be used with a wide variety of
intelligent products such as your
personal computers keyboard so these are
some of the applications of micro
controller over microprocessor the
number one we saw it is low cost it is
it is comparatively cheap cheap then
whom micro processor then number two it
is complex because it has many
input/output component then we saw it
can be used in wide variety of the low
cost products such as what electronic
toys then machines then medical
instrumentation chemical instrumentation
etc and it can be used in the wide
variety of intelligent products such as
what personal computer keyboards now
next we will see what are the features
of micro controller now we will have
look onto some features of 8:05 and
micro controller now this question is
very important as for your exam because
this patient may come for three max or
it may come for four max so obviously if
it comes for three max you have to write
any six features and if it comes for
four max then you have to explain at
least eight features so let us have a
look onto a feature number one it has a
bit ALU we already know what is a in you
are automatic and logical unit so 8:05
in microcontroller has 8-bit nu number
two it has four kilobyte of roll now
3 it has 128 bytes of RAM so the Rome is
of 4 kilobyte and the RAM is of 120 by
128 bytes so you can compare you can see
how limited memory it has as compared to
whom microprocessor next it has extended
dual tiny'mon counter it can address up
to 64 KB of program memory and it can
address up to 64 KB of data memory then
it has powerful instruction set
consisting of 111 instruction
instruction what is instruction said
that also we have studied in the
microprocessor so same as a
microprocessor microcontroller 8:05 and
microcontroller has some instruction set
and there are around 111 instructions
into it and it has two external
interrupts so these are the eight
features of microcontroller we'll have a
recap of this eight features again
number one it is a it has eight bit of
MU the number two it has four kilobyte
of role and 128 byte of RAM then it has
16 bit duel time event counter it can
address up to 64 KB of data memory as
well as program memory then it has the
powerful instruction set consists of 111
instruction and it has two external
interrupts so these are eight important
features of micro processor micro
controller thanks for watching this
video in the next video we will study a
memory map of 8:05 and micro controller
