https://devzone.nordicsemi.com/f/nordic-q-a/128973/nrf54lm20x-qfn-package-reference-designHi, I’m using the nRF54LM20x in the QFN52 package and noticed that reference designs are available for the other nRF54LM20x packages, but I couldn’t find one specifically for the QFN52. Should the nRF54L15 QFN52 reference design be used as-is ? en-USTelligent Community 13Tue, 18 Aug 2026 11:51:18 GMThttps://devzone.nordicsemi.com/thread/570388?ContentTypeID=1Tue, 18 Aug 2026 11:51:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e13c5210-fb7b-436a-ab7d-754ec6288fa5SwRa<p>Hi Jerome,</p> <p><span>You cannot use the nRF54L15 design/pin mapping for nRF54LM20x. We have a preliminary reference layout for QFN52 available which is available on request for customers with NDA from the sales team. Please contact your RSM if you need the preliminary reference layout. (Please note that it is just a preliminary design and the optimized design will be available later on.)</span></p> <p><span>SWO and TRACE are not available for nRF54LM20x for the QFN52 package.
