Description
This document will help application designers to become familiar with the megaAVR® families to migrate to the AVR® Dx MCU families, covering both differences and similarities. The comparison applies to most of the megaAVR vs. the AVR Dx products. In this document, the focus is on the ATmega128 and AVR128DA64, two generations of 128 KB Flash MCUs available in 64-pin packages.
