CY4615B AT2LP DDK User’s Guide

The AT2LP DDK board is a tool to demonstrate the features of the AT2LP (CY7C68300C and

CY7C68320C) mass storage bridge chips. Since the 100-pin CY7C68320C device is a

superset of the 56-pin CY7C68300C and CY7C68320C devices, this board can be used as an

evaluation platform for all devices in the AT2LP family.

Getting Started

By default, the AT2LP DDK board will be configured as a bridge to one or two ATA devices

in a self-powered configuration. If you would like to use this board as a bus-powered device or

if you would like to use the CompactFlash socket, you will need to change the board

configuration using the jumpers on the DDK board and the PC-based programming utility.

Here’s how to set up your board for the first time.

1. If you are using more than one device, configure one as a master and the other as slave.

If you’re only using one device, master/slave configuration will not matter.

2. Plug it into the 40-pin connector via the 80-pin ribbon cable.

3. Connect the 4-pin power connector to your external power supply

4. Connect your ATA device to an external power supply

5. Turn on the power supply and plug the USB cable into a host.
