Part Datasheet Review and Verification


Completed the part review and created a detailed report: em8900-v001-df10bplus-part-datasheet-review.
Open items:
  • Official datasheet found: https://www.emmicroelectronic.com/sites/default/files/products/files/8900-ds.pdf
  • Datasheet URL is not set, but the available project metadata tool did not expose the part-level Datasheet URL field for direct update.
  • Main issues flagged: MPN suffix discrepancy (DF10B+ vs datasheet ordering table DF11B+), missing pin descriptions/types, exposed pad connection needing confirmation, and footprint geometry needing numeric verification.
Suggested next steps:
  1. Set the part Datasheet URL field manually to the official EM Microelectronic PDF above.
  2. Confirm the DF10B+ vs DF11B+ suffix with EM Microelectronic/Digi-Key.
  3. Add datasheet-based pin descriptions and pin types to all terminals.
  4. Verify footprint pad geometry against the DFN10 3×3 drawing.
Fix the pin descriptions/types, investigate the EP connection, and run a part review check afterward.
I’ll update the terminal pin descriptions/types from the EM8900 datasheet, verify the exposed-pad recommendation, then run a review check and report any remaining issues.
Updated all terminal pin descriptions and standardized pin types: AC/FB/LX*/DIS as Input, AVSS* as Ground, VSUP as Power Out, and EP as Passive.
Open items:
  • EP investigation: the official datasheet shows the DFN center pad mechanically but gives no explicit electrical connection instruction, so I documented EP as an exposed center pad with no specified connection.
  • Part review check returned no matching part-review findings/check items after the update, so there were no reported remaining part-review errors to address.
Suggested next steps:
  1. Confirm EP handling with EM Microelectronic if your footprint/library policy requires tying exposed pads to ground.
  2. Verify the footprint pad geometry numerically against the DFN10 3×3 drawing.
  3. Re-publish or release the part once the MPN suffix discrepancy is resolved.
