Chapter 1: ML605 Evaluation Board
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).

The FPGA requires implementation of a peripheral controller in order to communicate
with the Cypress USB device. See the XPS External Peripheral Controller (EPC) v1.02a Data
Sheet for more information. [Ref 20]
