2 many operational codes for moving data from external
memory to cpu
3 rapid movement of code and data from externel address to
chip

microcontroller
1 specific purpose digital computer
2 one or two codes for moving data from external memory to
cpu
3 rapid movements of bits within the chip

Answer / pradeep

microprocessor:
> 1 or 2 bit handling Instruction
> There in in built memory
> There in no internal timer/counter
> Not having WDT,ADC,Serial port
> To make a computer some external accessory is required.
> general purpose digital computer.

microcontroller:
> More bit handling Instruction
> There is having internal memory
> In build timer/counter
> There is having WDT,ADC,Serial port In build.
> With out any external component can acts as a Digital Comp
> specific purpose digital computer.

Answer / sandeep

These are the diffrence. They are easy to understand.

Microprocessor = cpu
Microcontroller = cpu + peripherals + memory
Peripherals = ports + clock + timers + uarts + adc
converters +lcd drivers + dac + other stuff
Memory = eeprom + sram + eprom + flash

A microcontroller has a combination of all this stuff.
A microprocessor is just a CPU .

Some of them are 8051, 8255, 8253/8454(timer), 8279
(keyboard/display controller).

Hope, this information may be sufficient to you.

Answer / madhu rai

Microprocessor:-1.The ability to execute a stored set of
instructions to carry out user defined tasks.
2.The ability to be able to access external
memory chips to both read and write data from and to the
memory.

Microcontroller:-A microcontroller is a device which
integrates a number of the components of a microprocessor
system onto a single microchip.

So a microcontroller combines onto the same microchip :

Answer / vimalraj

Microprocessor:
it can be control Multiple Application.
eg. System Design.

Microcontroller:
it can be control Single or Particular Application Only.
eg. embedded systems.

Answer / a.shri ranjani

MICROPROCESSOR:
1.It has many instructions to move the data b/w memory and
CPU.
2.It has one or two bit handling instructions.
3.Access time for memory & I/O devices and more.
4.Microprocessor based system requires more hardware.
5.More flexible in design point of view.
6.It has single memory map for data &code
7.Less number of pins are multifunctioned.
MICROCONTROLLER:
1.It has one or two instructions to move data b/w memory to
CPU
2.It has many bit handling instructions.
3.Less access times for build-in memory and I/O devices.
4.It requires less hardware.
5.Less flexible in design point of view.
6.It has seperate memory map for data & code.
7.More number of pins are multifunctioned.

Answer / lavanya

MICROPROCESSOR MICROCONTROLLER
*General purpose applications. *Special purpose
applications.
*Used for processing data. *Used for controlling.
*Needs external memory. *On chip memory.
*We cannot interface it directly. *It can be interfaced
Eg:keyboaed interfacing using directly.
8255.

Answer / rajkumar s

microprocessor:it does not have seperate memory units for
code and data.
microcontroller:it will have seperate memory units for code
and data

Answer / joshy

microcontroller is using for specific task
processer is using for multi task
controller have cpu,periherals & memory
processer only cpu

Answer / jatin verma

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.
