Cypress USB 2.0 to ATA/ATAPI solutions support for more than one IDE device
Can Cypress USB 2.0 to ATA solutions support more than one IDE device at the same time?
AT2 solution based on CY7C68300A can only support one ATA/ATAPI device at a time.
However the AT2LP solution based on CY7C68300C/CY7C68301C/CY7C68320C/CY7C68321C chipsets support more than one IDE at the same time. The entire possible combination of devices supported by AT2LP are given below
1. ATA/ATAPI master only
2. ATA/ATAPI Slave only
3. ATA/ATAPI master and ATA/ATAPI slave
4. CompactFlash only
5. ATA/ATAPI slave and CompactFlash or other removable IDE master
CY4615 DVK board based on CY7C68320C supports the above mentioned configurations
The CY4611 board based on the FX2 (CY7C68013) chip, can also support two ATA/ATAPI devices at the same time - one set to master and one set to slave.
