Part Datasheet Review and Validation
Worked for 5 mins 30 sec
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:
- Fix the missing ball assignments and remove/merge the stray
C7terminal. - Update pin descriptions/types from the datasheet.
- Correct package/mount/type metadata to CSP98/SMD/RF SoC.
- Re-check the footprint geometry against the 98-ball CSP land pattern.
Thought for 1 min 3 sec
I’ll apply the datasheet-backed pin map cleanup, update terminal metadata, correct the part classification, then inspect the footprint geometry against CSP98 expectations.
Worked for 50 sec
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.
Worked for 13 mins 41 sec
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.Open items:
- Some schematic terminals still have null visual symbol positions, though their electrical pin numbers and descriptions are now correct.
- Library-search metadata may still show stale global classification until the part is republished/updated through the library workflow.
Detailed results are in Pin Map Fix Verification — NRF54LM20B-PAAA-R7.
