Overview

The AT43DK301 comes with everything designers need to develop a low-cost, selfand bus-powered USB Hub. To eliminate typical prototyping hassles, a fully populated stand-alone hub is included. Designers can take the stand-alone hub from the box to the system to see the operation of the AT43301 hub controller chip. The application note explains the component selection and resolves typical problems for the designer.

The hub may immediately be plugged into any USB system. The only requirements are that the system has an operational USB port and that the system has the USB drivers enabled on the operating system.

When connecting the hub, connect the power supply to the hub. The bus powered portion of the controller will configure without the power supply, but if devices are to be attached to the downstream ports, the power supply is required. Next, connect the upstream port to the USB connector on the computer.
