What is the HD3SS3220 UFP Dongle EVM?
illustrates the EVM block diagram.
Figure 1. EVM Block Diagram
The HD3SS3220 UFP Dongle EVM is designed to evaluate HD3SS3220 devices for UFP
implementations. This EVM can also be used as a hardware reference design for any implementation
using the HD3SS3220 with a USB Type-C™ connector. PCB design files can be provided upon request to
aid PCB design with the HD3SS3220. The layout files can be used as a guideline to implement the
TUSB321A with illustrations of the routing and placement rules. Please note that the EVM design may
include test components for evaluation purposes not applicable for production. The EVM includes an on-
board USB Type-A plug to connect to legacy USB systems.
