Completed the review and created Part Datasheet Review — NRF54LM20B-PAAA-R7.

Key findings: the official datasheet says this is a CSP98, 98-ball, 0.35 mm pitch part, but the Flux part currently has 99 terminals, including an apparent extra C7 terminal while P1.21 is missing its proper C7 ball assignment. Several other terminals are missing pin numbers/positions, all inspected pins are typed Unspecified, and metadata like Mount = Wire and Logic AND classification does not match an RF SoC.

Suggested next steps:

I’ll apply the datasheet-backed pin map cleanup, update terminal metadata, correct the part classification, then inspect the footprint geometry against CSP98 expectations.

I have the current pin list and allowed metadata values; next I’m applying the CSP98 ball-map corrections and terminal classifications from the Nordic datasheet.

Completed the pin-map cleanup and verification. The part now has 98 terminals/pads, the stray C7 terminal was removed, P1.21/ now maps to ball C7, pin types/descriptions were updated, and the footprint verifies as a 0.35 mm-pitch CSP98 grid with 98 pads.
