1.Microprocessor used for multipurpose such as calculating
and input/output etc. On the other hand, Micro-controller
used for specific purpose such as signals processing function.
2.Intel 8085,8086 are the examples of microprocessor, on the
other hand Microchip's pic series and Atmel's AVR series are
examples of micro-controllers.
3.Microprocessors are all-rounder and micro-controllers are
the master of one.
4.Microprocessor is just a cpu with internal registers and
requires external peripherals to interface with keyboard,
mouse, monitor,etc. On the other hand,Micro controller is a
complete system in itself. Timer, clock, ram, rom, memory
and drivers are inbuilt in micro-controller.
5.If you want to run a video game you need a microprocessor.
on the other hand,If you want to run a microwave oven you
need a micro-controller.
6.Microprocessor is designed for general purpose use in a
Computer. on the other hand, Micro-controllers are
frequently found in automobiles, office machines, toys,
ovens and washing machines etc.
7.Microprocessor used for processing not for controlling the
data of external devices, whereas micro-controller is used
to control the processing or events of environment.
8.Microprocessor does not having input/output ports. on the
other hand, micro-controller having input/output ports.
9.Microprocessor has normally more op-codes, few bit
handling instructions. on the other hand, in
Micro-controller op-codes are fewer and bit handling
Instructions are more.
10.Micro-controller are normally smaller in size as compared
to Microporcessor.
11.Microporcessor is a single Ic package, whereas
Mirco-controller is a single Chip.
12.Microporcessor needs other components for takes/provide
the input/output. on the other hand Mirco-controller do not
need other components.
