flux

Updated the part’s Datasheet URL to the official Azoteq IQS7211A PDF and completed the symbol/footprint cross-check. Full findings are in Part Datasheet Cross-Check: IQS7211A.
Open items:
  • Live metadata reports IQS7211A103QFR, while the initial project context said IQS7211A101QNR.
  • Symbol pin labels differ from the datasheet on several pins, especially CRXn/TXn vs RXn/TXn, GPIO aliases, and MCLR/GPIO6 vs MCLR/VPP.
  • TX8 and RDY are marked bidirectional but datasheet lists them as outputs.
  • If the intended part is QNR, the footprint should be checked against the QNR-specific footprint/corner-pad keep-out guidance.
Suggested next steps:
  1. Confirm whether the target MPN is IQS7211A103QFR or IQS7211A101QNR.
  2. Rename/update the symbol pins to datasheet-exact labels and pin types.
  3. Verify or revise the footprint for the confirmed QFR/QNR variant.

Check IQS7211A103QFR schematic component against the datasheet for [MPN] and assign the correct pin orientation, section, and terminal order without changing, replacing, renumbering, or remapping any pins. Place Power pins first , Ground pins last , and distribute all other pins evenly along the left and right edges so the symbol remains compact, balanced, and approximately symmetrical. If a pin function is unclear, assign Unclear / Check datasheet, then apply all changes directly to the schematic component.

I’ll verify the IQS7211A103QFR pin functions against the datasheet, then update only symbol metadata (orientation, section, terminal order) without changing pin numbers or mappings.

flux

Updated the IQS7211A103QFR schematic terminals with datasheet-based Pin Orientation, Section, and Terminal Order only; no pins were renamed, renumbered, replaced, or remapped.
Open items:
  • Ground was accepted for VSS and FLOAT, but Flux warned it is not in the current Section autocomplete list.
  • Existing pin labels such as CRXn/TXn and GPIO aliases were intentionally left unchanged per your constraint.
Suggested next steps:
  1. Regenerate/refresh the symbol view if needed to apply the new orientation/order visually.
  2. Optionally update pin types later for TX8/RDY if you want strict datasheet electrical typing.
  3. Optionally rename labels to datasheet-exact names in a separate pass.
