Hi

              The difference between microprocessor and microcontroller is the processor which can perform only software like operations it cannot control any parameters.hence the microcontroller will do that job.

                     In computers we are using the microprocessor and in industrial controls we are using microcontroller.

RE: differences between microprocessor and micro controller
  1. In Microprocessor more op-codes few bit handling instructions. But in Microcontroller: fewer op-codes more bit handling Instructions and also it is defined as a device that includes micro processor memory & input / output signal lines on a single chip.

RE: differences between microprocessor and micro controller
The basic Differnce is that a micro controller has got an inbuilt memory and ports where as micro processor needs memory to be interfaced with.

RE: differences between microprocessor and micro controller
The microprocessor is the integration of a number of useful functions into a single IC package.

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

Basically 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 : The CPU core Memory (both ROM and RAM) Some parallel digital I/O Essentially a microcontroller is obtained by integrating the key components of microprocessor RAM ROM and Digital I/O onto the same chip die. Modern microcontrollers also contain a wealth of other modules such as Serial I/O Timers and Analogue to Digital Converters.

Differences between microprocessor and micro controller
The basic difference is that microcontoller contains internal memory facilities such as ROM & RAM whereas in microprocessor we do not have such fadvantage.
In microcontroller we have many bit habdling instructions but in microprocessor we onlu one or two.

RE: differences between microprocessor and micro controller
Microcontollers are application specific while microprocessor is a multipurpose device which needs memory and i/o devices to be interfaced with.
up+i/o devices+ memory uc
