• Manufacturer Part Number: AT43DK312A
• Description: KIT USB HUB DEVELOPMENT AT43312A
• Manufacturer: Atmel

Specifications of AT43DK312A

• Lead Free Status / RoHS Status: Contains lead / RoHS non-compliant

Stand-alone Hub
The hub may immediately be plugged into any USB sys-
tem. 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.
The bus-powered portion of the controller will configure
without the power supply attached. However, the power
supply must be connected if the devices are to be attached
to the downstream ports. Next, connect the upstream port
to the USB connector on the computer. Windows will flash
a “New Hardware Found” box indicating the “Atmel USB
Hub” was detected and automatically load the generic USB
hub drivers. USB check tests or downstream devices can
then be used on the configured hub.
