INTROMUCTION

Earlier to Microcontrollers, Microprocessors were greatly used for each and every purpoVe. ÓicroproceVVorV were conWaining ALUH general purpoVe regiVWerH VWack poinWerH program counWerH clock counWer anT Vo many oWUer feaWureV wUicU W Microcontroller also possesses. But the difference between them exists with respect to ÓicroproceVVor conWainV large inVWrucWion VeW calleT aV CISC proceVVor wUereaV ÓicroconWroller conWainV leVV number of inVWrucWionV anT iV calleT aV RISC proceVVor. TUe acceVV Wime iV leVV in caVe of microconWrollerV compareT Wo microproceVVorV anT TUere are many verVionV of microconWrollerV 8051H 80528751H AT8951 from AWmel CorporaWion anT many more.
