AVR MICROCONTROLLERATMEL CORPORATION

INTRODUCTION

Atmel Corporation is a leading manufacturer of integrated circuits

Atmel’s AVR RISC microcontroller series

RISC processor with a Harvard architecture

Harvard architecture◦refers to the fact that the CPU has a

program memory and a separate data memory

Families of AVR Microcontroller

KEIL μVISION4

KEIL was founded in 1982 by Günter and Reinhard Keil

In October 2005, Keil (Keil Elektronik GmbH in Munich, Germany, and Keil Software, Inc. in Plano, Texas) was acquired by ARM.

CONCLUSION

“Anyone can cook”, it is the slogan of the movie RATATOUILLE

like that “Anyone can Program” the objective of my report is to make it clear that

anyone can prototype and easily work with the microcontroller.
