Part Metadata Audit and Datasheet Review

flux

I found the official ST datasheet and recorded it in the project metadata because a dedicated project-level Datasheet URL field is not available here. I’m now checking the 73 terminal pins against the UFBGA73 datasheet pinout.

Completed the part audit and created STM32WLE5JCI6 Part Audit.
Key findings: the part matches the expected STM32WLE5JCI6 UFBGA73 family at a high level — 73 schematic terminals and 73 footprint pads. I found the official ST datasheet URL and recorded it in project metadata because this workspace does not expose a dedicated project-level Datasheet URL property.
Flagged gaps: missing part-level MPN/manufacturer/package metadata, all terminal pin types are still Unspecified, pin descriptions are not populated, some pin labels should be normalized, and the footprint geometry still needs mechanical verification against the ST UFBGA73 drawing before manufacturing.

Fix the missing pin descriptions, pin types section based on the datasheet.

I’ll populate each terminal’s Pin Description, Pin Type, and Section from the STM32WLE5JC datasheet signal groups, then re-read the schematic to confirm the metadata is present.

flux

Done. I populated all 73 terminals with datasheet-based Pin Description, normalized Pin Type, and functional Section values.
I also corrected the initial non-standard values to Flux-supported ones like Bi-Directional, Power In, Power Out, Ground, Input, and Output, then verified the schematic metadata was updated.

STM32WLE5JCI6 Part Audit
Scope
Reviewed available part information in the current Flux part project: schematic terminals, pad count, layout footprint, metadata/properties, and available web/datasheet information.
Official Datasheet
The project did not expose a dedicated project-level Datasheet URL property for this part-project audit. I recorded the official datasheet URL in the project Implementation Details property.

Symbol / Terminal Cross-Check
Observed symbol terminals include the expected major signal groups for the UFBGA73 STM32WLE5JC family:
  • GPIO: PA0-PA15, PB0-PB15, PC0-PC6, PC13-PC15
  • Debug/system: PA13, PA14, PA15, NRST, PH3
  • Oscillator: PC14-OSC32_IN, PC15-OSC32_OUT, OSC_IN, OSC_OUT
  • RF: RFI_P, RFI_N, RFO_LP, RFO_HP, VR_PA, VDDRF, VDDRF1V55, VDDPA, VSSRF_1..VSSRF_4

The observed 73 schematic terminals match the observed 73 footprint pads.
Flagged Mismatches / Gaps
  1. Datasheet property location: No dedicated Datasheet URL project property is available in this workspace for the part itself. The URL was recorded in Implementation Details instead.
  2. MPN/manufacturer/package metadata: The current schematic terminal components do not carry part-level Manufacturer Part Number, Manufacturer Name, or Package or Case Code properties. The project name/description imply the MPN, but BOM/part metadata is incomplete.
  3. Pin descriptions: All inspected terminal components show Pin Type: Unspecified and do not include useful Pin Description text. This limits ERC/review quality and makes the symbol less self-documenting.
  4. Pin names needing normalization: Some terminal names include alternate function text (PB0-VDD_TCXO, PC14-_OSC32_IN, PC15-OSC32_OUT) while others use simplified aliases (OSC_IN, OSC_OUT) rather than explicit PH0/PH1 naming. This is not necessarily electrically wrong, but should be normalized to datasheet primary pin names plus alternate functions in pin descriptions.
  5. Full ball-map verification limitation: The official PDF was found, but the complete UFBGA73 ball-map table could not be reliably extracted by the available datasheet/OCR tooling. The current pin-number coordinate set and signal groups look consistent with UFBGA73, but final signoff should compare every ball against the PDF table manually or with a machine-readable ST pinout source.
  6. Footprint geometry not fully exposed: Layout inspection confirms 73 pads and one footprint, but did not expose pad diameter, solder mask, ball pitch, package outline, or courtyard dimensions. These should be checked against UFBGA73 5 x 5 mm, 0.5 mm pitch mechanical data before manufacturing.
  • Add true part-level metadata where the platform supports it: MPN STM32WLE5JCI6, manufacturer STMicroelectronics, package UFBGA73, datasheet URL https://www.st.com/resource/en/datasheet/stm32wle5jc.pdf.
  • Populate pin descriptions and pin types from the datasheet pin table.
  • Normalize oscillator/debug/alternate-function labels so primary ball names and alternate functions are clear.
  • Verify footprint geometry against the ST UFBGA73 mechanical drawing before using this part in a production board.
