Part Number: MSP432P401R
Tool/software: Code Composer Studio
Hello,
I am making a PCB for the MSP432P401R microcontroller. Could someone help me to get the part numbers for the HF and LF crystal oscillators used in the MSP432P401R launchpad? I tried to find it in the launchpad user's guide. But I did not get it.

Hi Keith,
Thank you for your quick answer to my post. I have another question. I am not sure if it is the right place to ask about it.
I am not going to use all the pins of MSP432P401R microcontroller. Do I need to pull down all the unused pins using external resistor? I was going through the following section of the technical reference manual. But, I am not completely sure whether it can also be done internally while I will write the code in CCS.

No, you can leave unused pins disconnected and can enable an internal pull-down if you'd like. Although, it might make sense to bring a few out to test points/pads in case you might need them in the future for debugging or a work around.
Thanks,
JD
