Part Number: TIDA-00287
Other Parts Discussed in Thread: TUSB4041I, TUSB8020B, TUSB8041A


I use the UP-Core. Fore some reasons I build a new Circuit for these Chip.
The new circuit should have two more USB 3.0 ports.
Is it pissoble to use these reference Design ?
with these design I would like to bring the two USB3.0 ports too the PCIE of my 100 Pin-Exheat at the UP Core.

Could someone help me?

friendly regards

  • Texas Instruments does not currently support any devices that go from PCIE to USB. You could use the USB 2.0 on the 100 Pins to expand to two or more USB 2.0s if you use a USB hub IC like the TUSB4041I.


  • Hello Mario,

    The TUSB8020B on the above mentioned reference design is a USB compliant Hub, so it would let you get two USB ports by using one of the available USB ports for the upstream connection; so you will have one additional USB 3.0 port (two USB SS ports total) on your UP board.

    If you need to have two or even three additional USB 3.0 ports (3 or 4 USB SS ports total), I would recommend you to check our TUSB4041A device.

  • Hello Jorge,

    I can't find any devices off the TUSB4041A. Is it possible with these component to get USB3.0 ports to the PCIe of my UP-Core?
    Then the component will be ideal too fix my problem. Is it possible to get a reference layout or a Datasheet of these?


  • Mario,

    The EVMs serve as reference designs for the TUSB4041 (USB 2.0 4 port hub) and the TUSB8041A (USB 3.0 4 port Hub), but we do not have a reference design to connect a hub to the PCIe of a UP-Core. You would need to use a USB host controller to do that. TI does not have a recommended USB host controller.
