What is difference between micro controller and micro processor?

Answer 1

* Microcontrollers are sub class of Microprocessor. * Microcontrollers are generally target specific. * For example when the application requirement is to capture 2 analog signals, 5 digital signals, store 512 bytes of data, and to place a time stamp (date & time). Ø Here in the case of processor we need a ADC to process the analog signal, ROM (512 bytes or greater memory size) to store 512 bytes of data, RTC (Real time clock) to get present date and time, of course digital signals can be captured using the I/O port pins, and a RAM also has to be added. This makes the size of the PCB pretty big. Ø In the case of controller all these are found inside it, our task is to select the controller based on the requirement. The microcontroller is basically a processor with some special features like ADC, DAC, RAM, ROM, etc., in it.
microprocessor is able to perform all the task done by micro controller but the microprocessor does not have any timers and counters internally for that operations it need the timers and counters from external. but micro controller can perform all the operations

Answer 2

An application specific processor uses a section of RISC and CISC Instruction set. That means it uses microcontrollers to acieve some dedicated task or application. An application specific processor executes multiple dedicated application in a syste
m having main control processor for controlling the operating of a system

Answer 3

microprocessor doesn't have its own memory

while microcontroller have its own memory

Answer 4

Both cannot be applicable for same applications, for complex signals DSP processor is used... where as the microcontroller

is used to control simple signals..

Answer 5

micro processor is havig off-chip memory.Micro controller is having on-chip memory.
