I found the official NXP datasheet and recorded it in the project metadata for traceability. Now I’m checking the 57 symbol pins and footprint pads against the datasheet.

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.
