Introduction

This document provides a description of how to upgrade the standard DSP56362EVM
Evaluation Module to the DSPD56362 and related components. After the upgrade is complete
the EVM system will be capable of autodectect/autoswitching of PCM, Dolby DigitalTM,
DTSTM and MPEG bitstreams in addition to various post decoder functions. The user interface
of the upgraded EVM is also described.

MOTOROLA DSPD56362EVM Upgrade Manual 1-1

SECTION 1

UPGRADE INSTRUCTIONS

1.1 INTRODUCTION

This section describes the instructions on how to upgrade the DSP56362EVM to have DSPD56362
decoder functionality. The DSP56362EVM upgrade kit allows user to replace the DSP, 68HC11, and
EPROM to add the following functionalities to the EVM:

• Auto-detection of Dolby DigitalTM, DTSTM, MPEG and PCM source.

• Standalone operation of EVM.

• LCD user interface for control and status operations.

1.2 UPGRADE KIT CONTENTS

The DSP56362EVM upgrade kit contains the following items:

• DSPD56362 Rev. D digital signal processor

• MC68HC711E9 Rev 3.0 microcontroller

• AT27LV010A Rev 1.0 EPROM

• Jumpers

• EVM Supplement Manual (this document)

The DSPD56362 Applications User Manual can be downloaded from Motorola’s website:
