CY4611B - USB 2.0 USB to ATA Reference Design
Updated to rev 2.5 on 9/1/2005. Now with Cypress's new EZ-USB FX2LP device enabling bus-powered operation and improved support for removable devices.
This reference design features the new EZ-USB FX2LP(TM) which enables bus-powered mass storage applications that take advantage of the high bandwidth capability of USB 2.0. This design supports ATA (Advanced Technology Attachment) specification modes through UDMA-100 for the highest performance USB mass storage solution available. The General Programmable Interface (GPIF) of the FX2LP allows glueless connection to the attached drive. This design provides all the materials necessary for production with the most flexible, highest-performance solution available.
