Board Overview

This section introduces the Atmel SAM3N Evaluation Kit design. It introduces system-level concepts,
such as power distribution, memory, and interface assignments.

The SAM3N-EK board is based on the integration of an ARM

®

Cortex

®

-M3 processor with on-board

Flash and a set of popular peripherals. It is designed to provide a high performance processor evaluation
solution with high flexibility for various kinds of applications.
