everett.pattisonA micro controller contains a lot of the parts a normal computer would have inside it. Some of these parts are the microprocessor, RAM, ROM and EEPROM memory and even Analog to Digital converters and input/output pins for controlling peripheral devices. A computer usually has all the hardware for these separately while the micro controller incorporates all these into a single integrated circuit.
So I guess you could say a microprocessor is a part of a micro controller in a way. -

may be but not totally as micro controller has less ports compared to processoreverett.pattisonA micro controller contains a lot of the parts a normal computer would have inside it.

Well yes, like most things, it can have more or less of something. But the basic idea is that micro controller has a smaller, less powerful processor than a computer microprocessor.narayana murthymay be but not totally as micro controller has less ports compared to processor

Exactly and now a days MCU manufacturer are launching small size microcontroller with advanced features.everett.pattisonWell yes, like most things, it can have more or less of something.

wow i don't know it can you explain it bro pleasegodfatherExactly and now a days MCU manufacturer are launching small size microcontroller with advanced features. -
P Santhosh Kumarits nice..
now i got an idea 😒
.... Thank u sir.. -

Like in 8051 microcontroller you don't have inbuilt ADC while now a days Microcontroller are available with low pin count and inbuilt ADC, Inbuilt Current and Voltage measurement which is useful in Energy Meter solutions.narayana murthywow i don't know it can you explain it bro please -

No need So Thank you Us We all Ceans are here to help each other. have a happy time on CE.P Santhosh Kumarits nice..
now i got an idea 😒

venueeemicro controller the name it self we have it controlls ,i.e no need of external effort but micro processor can work with in our control only.......

but i think all the modern micro controllers have all those featuresgodfatherLike in 8051 microcontroller you don't have inbuilt ADC while now a days Microcontroller are available with low pin count and inbuilt ADC, Inbuilt Current and Voltage measurement which is useful in Energy Meter solutions.
i think now a days manufactures are just thinking of improving capability but i got a doubt why can't we add more other advanced features other than adc and dac's -
Morningdot HabluHmm a nice thread to discuss the difference bet microprocessor and microcontroller.
I want to add one difference that no one mentioned here.Actually in microcontroller you have the facility to access or perform operation on single bit(like you can write MOV A,P1 to transfer the bit on p1 to accumulator).But in the case of microprocessor u cant.In microprocessor you only can perform operation on byte/bytes. -
maraitamilanmicrocontroller can be call it as microprocessor while the microprocessor cannot

praba230890ooohhh don't get confused by these answers....All u got to remember is that microcontroller's got memory in build with it whereas in processor it is not.....then after that only everything matters....

Well there are more advanced features than that. Most micro controllers incorporate an RS232 style serial module in their devices now for communication between devices. Some of comparator modules, some of Pulse-Width-Modulation (PWM) modules, and some have interrupts.narayana murthybut i think all the modern micro controllers have all those features

They have already implement lot of other modules also what i have said was just an example now a days Controller are available with internal I2C,SPI,RTC more than 2-3 Timer,ADC Channel,Current Channel,PWM,USB,CAN,LIN and many more.narayana murthybut i think all the modern micro controllers have all those features
