Usb Controller - Xilinx ML605 Hardware User's Manual

13. USB Controller

The ML605 provides USB support via a Cypress CY7C67300 EZ-Host™ Programmable
Embedded USB Host and Peripheral Controller (U81). The host port is a USB Type-A
connector (J5). A USB keyboard (without an internal USB hub) will be able to connect to
this USB Host port to demonstrate functionality. The peripheral port is a USB Type Mini-B
(J20).
Table 1-16: USB Controller Connections
See the Cypress CY7C67300 Data Sheet for more information.
In addition, see the USB Specifications for more information.
The FPGA requires implementation of a peripheral controller in order to communicate
with the Cypress USB device. See the XPS External Peripheral Controller (EPC) Data Sheet
(DS581) for more information.
