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)

UPGRADE INSTRUCTIONS

MOTOROLA DSPD56362EVM Upgrade Manual 1-3

1.3.1 DSP Replacement

To upgrade the DSP:

1. Use a Philips-head screwdriver to remove the 4 screws on the DSP socket U1.

2. Remove the socket top.

3. Remove the generic DSP using a chip suction device and replace it with the DSP included in

the upgrade kit. Verify that the DSP is placed in the socket securely and that the pins make

contact with the socket. Refer to Figure 1-1 for the correct orientation of the DSP.

Caution: To avoid damaging the DSP, use an anti-static wrist band when handling this

device. Using a device other than a chip suction device to lift the DSP may damage the

fine-pitched pins.

4. Replace the socket top and screw the top down.

1.3.2 68HC11 Replacement

To upgrade the 68HC11:

1. Remove the 68HC11 microcontroller from the socket U7 using a PLCC chip extractor device.

2. Replace the component with the 68HC11 included in the upgrade kit. Refer to Figure 1-1 for

the correct orientation of the 68HC11.

1.3.3 EPROM Replacement

To upgrade the EPROM:

1. Remove the EPROM from the socket U6 using a PLCC chip extractor device.

2. Replace the component with the EPROM included in the upgrade kit. Refer to Figure 1-1 for

the correct orientation of the EPROM.

1.3.4 Jumper Settings

Figure 1-2 shows how to modify the jumper settings:
