Datasheet title/version/date reported by web extraction: EM8900 Data Sheet, version 4.2, 6-Oct-2025
Note: The project does not currently expose a part-level Datasheet URL field through the available editable project metadata tool. The datasheet URL should be set to the official URL above when that property is available in the part editor.
Datasheet ordering/package notes
The official datasheet extraction reports ordering information for EM8900-V001-DF11B+, not EM8900-V001-DF10B+, while distributor data references EM8900-V001-DF10B+. Both are associated with EM8900 and DFN10 3 mm × 3 mm packaging. This suffix discrepancy should be confirmed with EM Microelectronic or the distributor before publishing the part as exact.

Needs confirmation/description update
Footprint review
Observed PCB footprint contains pads for AC, FB, LX2, LX1, LX0, AVSS0, AVSS1, AVSS2, DIS, VSUP, and EP, totaling 11 pads including the exposed pad. Silkscreen/fab outline indicates a 3 mm × 3 mm body with pin-1 marker, consistent with DFN10 3×3 at a high level.
Detailed pad geometry was not exposed in the layout inspection output, so terminal width/length, pitch, and exposed-pad dimensions could not be numerically verified from the tool output. The footprint should be checked against: 0.50 mm pitch, 0.25 ± 0.05 mm terminal width, 0.40 ± 0.10 mm terminal length, and 1.70 × 2.40 mm exposed pad.
Mismatches / issues to fix
Datasheet URL missing in project properties: The part project has no accessible datasheet URL set; official URL is https://www.emmicroelectronic.com/sites/default/files/products/files/8900-ds.pdf.
MPN suffix discrepancy: Project MPN is EM8900-V001-DF10B+, but the current official datasheet extraction lists EM8900-V001-DF11B+ in the ordering table. Confirm whether DF10B+ is a distributor/orderable alias, older suffix, or incorrect MPN.
Pin descriptions are not populated: All terminals currently show Pin Type: Unspecified and no visible Pin Description. Add datasheet descriptions to each terminal.
Exposed pad description missing/ambiguous: Project uses EP as Pin 11. Datasheet pin table lists only pins 1–10, while the mechanical drawing shows a central pad. Confirm whether EM requires exposed pad connection to AVSS/ground and document it in the EP pin description.
Footprint geometry not fully verified: High-level pad count/body style is consistent, but exact pad dimensions were not available from inspection output.
