  Hello Manohar, TM4C1290NCPDT is a possible option here. USB High Speed support is only available through an external USB PHY connected over ULPI but that support is possible and demonstrated with the following TI design: https://www.ti.com/tool/TIDM-T…

  Hello Viktorija, The transceiver in question provides a PHY that handles USB High Speed 2.0. Are they going to be operating in USB High Speed mode? If so, then they wouldn't need the VBUS and ID connections and could use them as non USB pins, and would…

  Hello Gute, gute1 said: unfortunately the TM4C123 does not have a high-speed built-in (only with external device) TM4C123x I don't think can support high speed in any situation. TM4C129x devices can support USB 2.0 High-speed using an external PHY…

  Hi, TM4C USB controller is compliant with USB 2.0 standard, not 3.0. This is the clarification I want to make on the MCU USB controller side. Please refer to the datasheet for detail. I also show the excerpt below. I find one USB 3.0 (TUSB1310A) but…

  Hi Andy, Great to see the proof of concept worked well. You should be able to clone how the bulk descriptors are handled for the most part then to make the custom MIDI descriptors. Might be a bit tedious with all the structures, but hopefully that gives…

  Hello Karen, TM4C devices do not support USB 3.0. I am not even sure if USB 3.0 was even a released standard when the USB interface was designed. USB 2.0 high speed requires an external USB PHY, we have a TI Design showing this: http://www.ti.com/tool…

  Hello Phil, The board does not have a USB 2.0 PHY installed, you would need to interface one to it via the EPI ULPI interface. We don't have a development board that we sell with USB 2.0 capability, but we do have a TI design including BOM and gerbers for…
