EVB-USB4715 OVERVIEW

The EVB-USB4715 is a demonstration and evaluation platform that provides the nec-

essary requirements and interface options for evaluating the USB4715, a 4-Port HS

USB Smart Hub on a 4-layer RoHS-compliant Printed Circuit Board (PCB). This will

allow the user to gain an understanding of the product and accelerate the integration

of the USB4715 into the user’s design. The USB4715 is compliant with USB 2.0

High-Speed (HS), Full-Speed (FS), and Low-Speed (LS) USB signaling. The evaluation

platform supports four downstream ports; two USB 2.0 ports with Type-C™ connectors

and two standard Type-A USB 2.0 ports. The EVB-USB4715 platform also supports

battery charging on all four ports (maximum of 10A* at any one time). The

EVB-USB4715 is configured for operation through internal default settings and sup-

ports custom configurations through SMBus or through the external 16-Mbit SPI Flash

device. The EVB-USB4715 supports FlexConnect role reversal for any of the four

downstream ports with the upstream port. The EVB-USB4715 demonstrates driver

compatibility with Microsoft® Windows® 10, Windows 8.x, Windows 7, Windows XP,

Mac OS® X 10.4+, and Linux® hub drivers.
