An Overview of Microcontroller Unit: From Proper Selection to Specific Application

It is very difficult to choose a particular Microcontroller for specific application. Success or failure of any project largely depends on proper selection of the Microcontroller Unit. In this paper a brief overview of the unit is described as far as the right selection for particular application is concerned. So many manufactures are producing microcontroller in bulk amount. Comparison is based on products of few leading manufactures. System requirements, availability, performance, size, power dissipation, flexibility, Reliability, Maintainability, Environmental constraints, software support, correctness, safety, Cost, manufacturer’s history and track records are the vital factors to be considered whenever a system is to be implemented using a microcontroller which is the heart of the device. In this paper several factors are focused and follow up of those factors leads to success of the project.
