AVR32933: EVK1105AU Getting Started Guide
Features
• Powering up the board
• Preparing the board for audio playback
• Playing music
1 Introduction
The EVK1105AU is a reference design and development system for the
AT32UC3A0512AU, a 32-bit Atmel
Corporation.
From a hardware point of view, the EVK1105AU is identical to the EVK1105, so
you can refer to the EVK1105 for more information (schematics, BOM, etc.). The
only difference is that the main microcontroller is an AT32UC3A0512AU instead of
an AT32UC3A0512.
The AT32UC3A0512AU is an audio microcontroller that authorizes execution of
Atmel licensed Audio firmware IPs such as commercial MP3, AAC, WMA audio
decoders.
The kit is equipped with a rich set of memories and peripherals that make the
EVK1105AU a perfect audio platform. This guide shows the user how to get quickly
started with this kit.
