TM4C129EKCPDT: TM4C129x series

Part Number: TM4C129EKCPDT
Other Parts Discussed in Thread: TM4C1294NCPDT, EK-TM4C1294XL

I am following the workshop - TM4C1294XL Connected LaunchPad Workshop. Now in TM4C129x Overview, it was mentioned that it supports USB HS with external PHY via ULPI (page 9/336 workshop book), -

but later in the microcontroller feature (page 13/336 workshop book), it's mentioned that the TM4C1294NCPDT support USB FUll and LOW-speed USB 2.0-


Can I develop USB 2.0 High-speed application using the board?

 

Thank you.

  • Hello Arindam,

    The TM4C1294NCPDT has integrated support for Full and Low Speed USB2.0. For High Speed USB 2.0, an external PHY is needed. So the TM4C1294NCPDT does support High Speed USB, but additional external hardware is needed for that.

    Now then, specifically for the LaunchPad, the EK-TM4C1294XL does NOT have the required hardware for High Speed USB development on board. We don't have an evaluation kit which has this built in, but the DK-TM4C129X has a header which is brought out that can allow connections for the ULPI connections needed for the external USB PHY.

    We also have a TI design for hardware and software design for High Speed USB: www.ti.com/.../TIDM-TM4C129USBHS
