Part Datasheet Review and Validation

flux

Found the official ST datasheet and added its URL to the project properties. I’m now checking the imported pins and footprint against it.

Reviewed the STM32WLE5JC part and added the official ST datasheet URL: https://www.st.com/resource/en/datasheet/stm32wle5jc.pdf.
Key specs: STM32WLE5JC is an Arm Cortex-M4 Sub-GHz wireless MCU with LoRa/(G)FSK/(G)MSK/BPSK radio, 150–960 MHz RF range, 256 KB Flash, 64 KB SRAM, 1.8–3.6 V supply, and UFBGA-73 5 × 5 × 0.6 mm package with 0.5 mm pitch.
Findings / mismatches flagged:
  • The project description says “0.6mm UFBGA-73”, which is ambiguous/misleading: ST lists 5 × 5 × 0.6 mm body, 0.5 mm pitch.
  • Project metadata only has Package or Case Code = UFBGA; it should ideally specify UFBGA-73, 5 × 5 × 0.6 mm, 0.5 mm pitch.
  • Schematic has 73 terminal pins, matching the package ball count, and sampled pins match datasheet examples such as A1 = VSSSMPS, B1 = VLXSMPS, C1 = PB3.
  • Footprint shows a 5 mm × 5 mm outline and 73 BGA pads on a 0.5 mm grid, consistent with ST’s package summary.
  • Pin descriptions are mostly basic pin names/types only; detailed alternate/additional functions from the datasheet are not populated.
