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).
