Introduction to Microcontroller 8051 – Microcontroller and Its Applications


Do subscribe to Ekeeda channel and press bell icon to get updates about latest Engineering HSC and IIT-JEE Mains and Advanced videos.Hello Friends, In this video we will study that what is a Microcontroller so let us start with the topic. This word Microcontroller it is composed of two terms micro plus controller micro means very small in size and controller beings a device which controls the operations of all the devices okay so here we have the word micro for small and controller means controls all the operations so micro controller we can say that they are the devices which are very small in size and they control the operations of the of all the other devices okay now micro controller or general micro controller it consists of various components like memories there and this memory can be either RAM or room Ram is the random access memory and Rome is the read-only memory okay so this microcontroller it can have memory it can have serial input output ports also it can have the peripheral devices okay and timers and counters all those are there in the microcontroller so we can say that the microcontroller it generally consists of all these components so a microcontroller talking about its components it will have built-in RAM roam input/output ports serial ports timers interrupts and clocks of gauge hall will be present in the microcontroller so we can say that microcontroller it is nothing but it’s an on-chip computer ok all the devices of the computer they are embedded on a single chip that will be called a microcontroller so another name for microcontroller is the on chip computer because it is having all the components which are embedded on a single chip now if we compare this microcontroller with the micro processors so micro processors they are having the central processing unit that is CPU they will have a separate memory separate block for the input/output ports and separate block for the interrupts timers and clock circuits so everything is separate on that micro processors so but in the case of micro controllers because it is having all the things on one chip so we can say that all the features of the micro processors they are of the micro processors they are contained in the micro controller so micro controller it is comprising the features or it has a micro processor plus it has the memory section and the input/output section also you so all the components of the microcontroller they are in the microprocessor plus the internal remainder and the parallel and serial ports so if we combine all these things we will find out the microcontroller so we can say that microcontrollers incorporates all features of the microprocessor now as the microcontroller because it is a type of controller it is controlling all the functions so they are very powerful devices you so as they are controlling the functions so when the via the microcontrollers they are used in the any application so they will access the dedicated devices which are controlling all the functions if we take an example here the example of this is like a microcontroller they can be used as the engine controllers in the automobiles they are also used in the washing machine in the V CD players and in the microwave ovens for controlling the temperature there in the ovens if we want to control the temperature that is done by the microcontroller so for any specific task if we want to use some device for a specific task we use the micro controllers so as an engine controller in automobiles also as the exposure and focus controllers in the cameras also the microcontrollers are used so in all the applications we’re controlling is required microcontrollers can be used now as the microcontrollers it has all the devices which are embedded on the single chip that is the memory and those input/output both serial ports timers counters all are present on a single chip so for their manufacturing the CMOS technology is used and you do the CMOS technology the size of these microcontroller is very small that is by the word micro is there that is microcontrollers they are very small in size because we are using the CMOS technology and all these small devices they are embedded on the same chip so these aren’t chip peripherals the input/output port serial ports they are selected according to the tasks performed by the microcontroller in a particular application so if you want to use the microcontroller for automobiles we will have the different operations have to be performed for microwave ovens in different operations are to be performed so for depending upon the applications the peripherals are chosen so we can say that on chip peripherals they are selected according to the tasks performed in the application so on super refills they are selected depending upon the specifics that is specifications of the target application for which application the microcontroller is to be used now as these microcontrollers they are powerful devices digital processors so the degree of control provided by these micro controllers and the programmability it provides significantly it is going to significantly enhance the effectiveness of the application because if in an application if you are using a microcontroller in place of a microprocessor the effectiveness or the efficiency of the application will be increased in the case of microcontroller because they are very powerful devices digital processors and they can better control the operations of the applications so these microcontrollers we can say that they increase the efficiency of the application now different applications of this microcontroller we know that they can be used in washing machines in BCD player in microwave oven in robotics also micro controllers are used and in industries also micro controllers are used so these are the various applications of the micro controller we have the applications in the robotic field also and in the industrial field also okay now talking about the development of the micro controllers the Intel company it designed the first micro controller which is the 8:05 1 micro controller until design the first microcontroller and this first microcontroller is known as 8:05 one micro controller this microcontroller was developed in late 1970s means in nineteen now it is we can say 1981 it was developed by the Intel and this microcontroller it is an 8-bit microcontroller 8-bit microcontroller means we can classify this microcontroller on the basis of the bits processed by them so 8:05 phone is an 8-bit microcontroller means it can read write and process 8-bit data so whatever microcontroller which is dealing with 8-bit data that will be called an 8-bit microcontroller if it is dealing with 16-bit data then it will be called 16-bit microcontroller and if it is dealing with 32-bit data then it will be called as 32-bit microcontroller so 8:05 point was 8-bit microcontroller and all the microcontrollers which belong to this family they are known as MCS 51 family ok so all these micro controllers which are of 8-bit they will belong to this family so this was done little bit introduction of what is a microcontroller what which is the first microcontroller design and what are the applications of this microcontrollers so I hope that now this topic is clear to you that what is a microcontroller thank you
