AVR Basics The AVR microcontrollers are divided into three groups: 1. tiny AVR 2. AVR (Classic AVR) 3. mega AVR 4. xmega AVR The difference between these devices lies in the available features. The tinyAVR μC are usually devices with lower pin-count or a reduced feature set compared to the mega & xmega AVR's. All AVR devices have identical
