Difference between 8051 and 8096 microcontroller

Answer 1

Difference between Microprocessor and Microcontroller

Microprocessor Micro Controller

1G mobile phone

1G mobile phone

Microprocessor is heart of Computer system. Micro Controller is a heart of embedded system.

It is just a processor. Memory and I/O components have to be connected externally Micro controller has external processor along with internal memory and i/O components

Since memory and I/O has to be connected externally, the circuit becomes large. Since memory and I/O are present internally, the circuit is small.

Cannot be used in compact systems and hence inefficient Can be used in compact systems and hence it is an efficient technique

Cost of the entire system increases Cost of the entire system is low

Due to external components, the entire power consumption is high. Hence it is not suitable to used with devices running on stored power like batteries. Since external components are low, total power consumption is less and can be used with devices running on stored power like batteries.

Most of the microprocessors do not have power saving features. Most of the micro controllers have power saving modes like idle mode and power saving mode. This helps to reduce power consumption even further.

Since memory and I/O components are all external, each instruction will need external operation, hence it is relatively slower. Since components are internal, most of the operations are internal instruction, hence speed is fast.

Microprocessor have less number of registers, hence more operations are memory based. Micro controller have more number of registers, hence the programs are easier to write.

Microprocessors are based on von Neumann model/architecture where program and data are stored in same memory module Micro controllers are based on Harvard architecture where program memory and Data memory are separate

Mainly used in personal computers Used mainly in washing machine, MP3 players

Answer 2

Difference between 8051 and 8096 microcontroller is given below

Explanation:

• Bits comparison:

if we compare the bit between the 8051 and 8096 microcontrollers.The 8051 microcontroller holds the 8 bits whereas in the 8096 microcontroller it holds the 16 bit.

• Accuracy:

If we compare the accuracy between the 8051 and 8096 microcontrollers.The 8051 microcontrollers executed the arithmetic operation such as addition operation, etc however in 8096 microcontrollers they give precise and correct results then compare to 8051.
