Reviewed the PCA9450CHNY part information against the official NXP datasheet and recorded the findings in PCA9450CHNY Part Review.

Summary: the MPN, i.MX8M Plus target, HVQFN56 package, 57 layout pads including EP, and pin numbering are broadly consistent. I flagged two naming mismatches (BUCK_A_GND vs BUCK_AGND, SW_OUT vs SWOUT), incomplete pin type/description metadata, EP being represented as pin 57, and the need to verify the footprint geometry against the SOT949-6 mechanical drawings.

I’ll update every terminal with datasheet-derived Pin Type and Section values, then re-read the schematic to verify the metadata landed correctly.

The first update landed, but the editor flagged non-standard Pin Type/Section labels. I’m normalizing them to the platform’s accepted values while preserving the datasheet intent.

Updated all 57 PCA9450CHNY terminals with datasheet-based Pin Type and Section metadata, then verified the schematic.

I normalized the values to accepted options: power pins are now Power In/Power Out, ground pins are Ground, I/O pins are Input/Output/Bi-Directional, and open-drain outputs POR_B/IRQ_B are Open Collector. Sections are assigned by primary function: Voltage Regulator, Power, Reset, Clock, Enable, Control, and Interface.
