Micropocessors; need external preferals to work like
EEPROM for program to be runned, RAM to save data into it, external clock,
external I/O ports and of course collections of buffers, Bi-Directionals,
and decoders.
Microcontrollers; are integerated device contains CPU core, and EEPROM,
RAM, I/O ports, Internal Clock, of course it's functions are weak and slow
if compared with Microporocessors, but they wholy stand alone system
Microprocessor is only the processor and no peripherals are integrated like
memort controller DMA etc.
but the are very high speed chips
where as the microcontroller are integrated with various devices like ADC DAC USB memmory etc the are not so high speed and since every thing is integrated it is easier to use and cost is very less compared to Processors
Microprocessor is a microprocessor although is more powerful than microcontroller. Microcontroller indeed is a computer,loosely based, because has everything.
Take one example I/O ports. Computer has them. Microcontroller has them. Microprocessor does not have them. Difference between computer to a microcontroller is level of those I/O ports. There are more differences like power etc. like even ancient computers are faster then a microcontroller for example.
Re: What's the microcontroller and what's the microprocessor
Microcontrollers having builtin memory and general purpose IOs.(You can it switch as serial,parallel,special ,analog, pwm and other.
Microprocessor can you use only with outer pheripherial.
Microcontrollers are used in the field industry control or the embedded application, they have the IO device such as the timer/counter, UART, PWM, AD/DA, SPI, FastIrda etc.
Microprocessors are used in the field computer.
Re: What's the microcontroller and what's the microprocessor
Hi,
Microcontroller is a system on a single chip, whereas the microprocessor is a chip in a computer system.
Microcontroller with its integrated pheripherals is a low cost chip and is mainly used in embedded systems, which require limited data processing .
Microprocessor is mainly used in general purpose PC's.
The main difference lies in processing speed and data handling capacity.
Re: What's the microcontroller and what's the microprocessor
"A microcontroller is a computer-on-a-chip optimised to control electronic devices. It is a type of microprocessor emphasizing self-sufficiency and cost-effectiveness, in contrast to a general-purpose microprocessor"
