Pin Grouping Datasheet

flux

Grouped all 60 STSPIN9P24TR terminals by datasheet-backed function, including EPAD1–EPAD5, with each physical pin assigned to exactly one Pin Group. I also set Section equal to Pin Group, added pin descriptions, normalized Pin Type values, and verified the updates.
Open items:
  • None.
Suggested next steps:
  • Regenerate/review the parametric symbol layout.
  • Run a quick part-quality review against the datasheet pin table.
  • Publish the component if the symbol/footprint now looks correct.

  • Make the functional group more general.
  • Add a Section property to all pins, and apply the same value used in the Pin Group property to each pin's Section property.
Assign a Terminal Order from 1 to 10, starting with Power. Power should be Terminal Order 1, and Ground should be last, Terminal Order 10. For Orientation, set Power to "Top" and Ground to "Bottom." For the remaining sections/groups, you may decide the Terminal Order and Orientation yourself. For Orientation, distribute them between "Left" and "Right" — don't put everything on one side. Each group/section should have a different orientation.

I’ll simplify the pin groups into broader categories, keep Section identical to Pin Group on every terminal, and rebalance order/orientation with Power first and Ground last.

flux

Updated the STSPIN9P24TR pins to broader functional groups: Power, Output, Analog, Control, Status, and Ground. Every pin now has a matching Section value, Power is order 1 / Top, Ground is order 10 / Bottom, and the remaining groups are distributed Left/Right with distinct orders.
Open items:
  • None.
Suggested next steps:
  • Regenerate/review the parametric symbol view.
  • Run a quick visual check to confirm the grouped symbol layout is readable.
