Microcontroller: Microcontroller is termed as one on chip laptop which incorporates range of peripherals like RAM, EEPROM, Timers etc., needed to perform some predefined task.
The laptop on one hand is meant to perform all the overall purpose tasks on one machine such as you will use a laptop to run a code to perform calculations otherwise you will use a computer to store some transmission file or to access web through the browser, whereas the microcontrollers are meant to perform solely the precise tasks, for e.g., shift the AC off mechanically once temperature drops to a precise outlined limit and once more turning it ON once temperature rises on top of the outlined limit.
There are range of standard families of microcontrollers that are utilized in completely special applications as per their capability and practicableness to perform the required task, most typical of those are 8051, AVR and PIC microcontrollers. During this article we are going to introduce you with AVR relations of microcontrollers.
History of AVR
AVR was residential inside the year 1996 by Atmel conglomerate. The design of AVR was industrial by Alf-Egil Bogen and Vegard Wollan. AVR derives its name from its developers and stands for Alf-Egil Bogen Vegard Wollan reduced instruction set computing microcontroller, conjointly called Advanced Virtual reduced instruction set computing. The AT90S8515 was the primary microcontroller that was supported AVR design but the primary microcontroller to hit the industrial market was AT90S1200 within the year 1997.
AVR microcontrollers are out there in 3 categories:
1. TinyAVR – Less memory, small size, appropriate just for easier applications
2. MegaAVR – These are the foremost standard ones having smart quantity of memory (upto 256 KB), higher range of built-in peripherals and appropriate for moderate to complex applications.
3. XmegaAVR – Used commercially for complicated applications, that need giant program memory and high speed.
The following table compares the higher than mentioned AVR series of microcontrollers:
