Part Datasheet Audit


Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
I’ll audit the part metadata and existing assets, locate the official ST datasheet if needed, update the Datasheet property, then cross-check symbol pins, footprint, and descriptions against the manufacturer documentation.

Part Datasheet Audit Scope and source
Audited the current part project for ST25R3916B-AQET against the official STMicroelectronics datasheet:
Existing part metadata Ordering-code interpretation
  • ST25: NFC/RFID devices
  • R: NFC/HF reader
  • 3916B: full-feature NFC reader
  • A: -40 °C to +105 °C ambient range
  • QE: 32-pin UFQFPN, 5 x 5 x 0.55 mm, non-wettable flanks
  • T: tape-and-reel
Symbol and terminal audit
The symbol contains all 32 numbered pins plus terminal 33 for the exposed ground pad. Most pin names and numbers match Table 2 of the datasheet.
Audit complete. The existing Datasheet URL is already the official STMicroelectronics datasheet, so no property update was needed.
Key issues found:
  • TAD1/TAD2 are swapped between pins 2 and 25.
  • AQET is UFQFPN32, not WLCSP/36-UFBGA.
  • Footprint pads differ from ST’s recommended land pattern.
  • All pin types are unspecified and pin descriptions are missing.
  • “Logic Function: AND” is incorrect.
Full specifications and comparisons are in Part Datasheet Audit. I also filed an internal part-quality report.
