Selecting a Microcontroller Architecture for your Embedded Project

comparing 8051,PIC,AVR and MSP430 architecture for embedded projects

Selecting a Microcontroller architecture for your embedded system project can be one of the easiest or difficult decisions you will ever face as an electronics engineer or as a casual hobbyist.There are bewildering arrays of micro controllers from hundreds of vendors with different price points and feature sets.

The best and easiest advice i will give to any person is to go with an architecture or microcontroller you are already familiar with.Most of your embedded projects can be implemented with your favorite micro controller architecture.However this approach will not work when you are working on a project with strict constraints on Power,Space or project budget.In such cases we have to select a custom microcontroller architecture that will suit our unique needs.

This article written for students or hobbyists who  are starting out on embedded systems and wants to select their first microcontroller.
