TMS320F28030: Pull down resistor

Part Number: TMS320F28030

Hello, there are several GPIO which have 15K, pull-down resistor.  At power-up (the device is reset and GPIO are inputs),  does the 15K pull-down pose a problem? 

thanks 

  • Allen,

    no a pull-down is actually recommended on signals that need to reliably boot into a desired state.

    If the pin defaults to enabling its internal pull up, I would recommend disabling the internal pull up for efficiency, but this should not cause a problem.

    Please note if desired a stronger external pull resistor can be used if that helps you application.

    Regards,
    Cody
