N556 vs N547 differences in Pin reset values

WilliamDavy — Fri, 23 Jan 2026 20:18:52 GMT

Are there any differences in the default Pin configuration (performed by the BootROM or otherwise) between the N556 vs the N547? Specifically, do all of the pins in the N556 follow the default values (typically high-Z inputs) as specified in the manual or are there any that are configured differently to the N547.

Hello @WilliamDavy

MCXN556 is not a mass‑market product. I’m sorry, but as the online support team, we do not have any materials available for this device. Please refer to the user manual and datasheet for details, or contact the people who provided the chip for further support.

Thank you.
