msp432 launchpad max current

Other Parts Discussed in Thread: ENERGYTRACE

I cant found informations about EnergyTrace MSP432 LaunchPad maximum current value ?
Anybody knows ?

  • Lukasz,

    I don't know if it is the right answer, but in this thread

    it says "Target current exceeded with the maximum current (75mA) supported by EnergyTrace."

  • Hi Lukasz.

    I found this from  SLAU597A - MSP432P401R LaunchPad™ Development Kit User's Guide

    2.4.1 XDS110-ET USB Power
    The most common power-supply scenario is from USB through the XDS110-ET debugger. This provides
    5-V power from the USB and also regulates this power rail to 3.3 V for XDS110-ET operation and 3.3 V to
    the target side of the LaunchPad. Power from the XDS110-ET is controlled by the isolation block 3V3
    jumper, ensure this jumper is connected for power to be provided to the target MCU side.
    Under normal operation, the LDO on the XDS110-ET can supply up to 500 mA of current to the target side
    including any BoosterPacks plugged in. However, when debugging and using the EnergyTrace technology
    tool, this current is limited to 75 mA total. Be aware of this current limitation when using EnergyTrace
    technology.

  • Interesting to know, thanks.
