Why does the FRDM‑MCXA346 Design Files archive contain a schematic for FRDM‑MCXA166?

Hello,

while reviewing the FRDM‑MCXA346 design files from the NXP download section, I noticed that the included schematic is labeled for FRDM‑MCXA166 instead of FRDM‑MCXA346.

Could you clarify:

Is this intentional and are both boards sharing the same schematic?
Or is this a packaging error in the archive?
Are the MCXA166 and MCXA346 MCUs actually different devices, or is MCXA346 just a newer designation for MCXA166?

I would appreciate if someone from NXP could confirm whether the provided schematic is correct for FRDM‑MCXA346.

I downloaded the archive from the NXP page, and it is named "FRDM‑MCXA346‑DESIGN‑FILES.zip"

Thanks in advance!
