Check this schematic component against the datasheet for [MPN].
Compare all pins with the datasheet and assign for each pin: pin orientation, section, and terminal order.
Important:
Do not replace pins, do not change pin numbers, and do not remap pins.
Only assign the correct properties: orientation, section, and terminal order.
Power pins must be first in the terminal order.
Ground / GND pins must be last.
Place all other pins between them into sections according to the datasheet: Input, Output, Control, Analog, Digital, Interface, RF, NC, Unclear / Check datasheet.
If one section has many pins, do not place all pins on one side of the symbol. Distribute them logically on both sides of the symbol: Left and Right, so the schematic symbol is balanced and easy to read.
If a pin function is unclear, do not guess; assign section Unclear / Check datasheet.
Terminal order must be logical for the schematic and match the datasheet.
Apply these assignments directly to the schematic component.

Understood — I’ll keep every existing pin and pin number intact, and only assign Orientation, Section, and Terminal Order based on the STM32H743IIT6 LQFP176 datasheet.

flux

All 176 existing terminals have now been assigned Pin Orientation, Section, and Terminal Order without changing pin numbers or remapping pins; I’m verifying the applied metadata and finishing the datasheet audit.

Completed: all 176 existing STM32H743IIT6 terminals were checked against the LQFP176 datasheet pinout and assigned Pin Orientation, Section, and Terminal Order without changing pin numbers or remapping pins; details are in STM32H743IIT6 Part Datasheet Audit.
Open items flagged: Package or Case Code is incorrectly TO instead of LQFP176/176-LQFP, and terminal Pin Type / Pin Description metadata is still incomplete because your edit scope limited changes to orientation, section, and order.
Suggested next steps: update the package metadata, populate pin types/descriptions from Table 9/Table 10, then run the component review checks again.

Symbol pin comparison result
All 176 existing schematic terminals were checked against the datasheet LQFP176 pinout. Pin names and pin numbers match the datasheet pinout used for STM32H743IIT6; no pins were replaced, renumbered, or remapped.
Applied terminal assignments
The following properties were applied directly to the existing 176 terminal components:
  • Terminal Order 1-20: supply pins; Pin Orientation = Top; Section = Power.
  • Terminal Order 21-28: reset, boot, power-down, wakeup, and oscillator controls; inputs on Left, oscillator outputs on Right; Section = Control.
  • Terminal Order 29-30: analog-only PC2_C and PC3_C; Pin Orientation = Left; Section = Analog.
  • Terminal Order 31-163: bidirectional GPIO/peripheral interface pins; distributed Left for datasheet pins 1-88 and Right for datasheet pins 89-176 to keep the symbol balanced; Section = Interface.
  • Terminal Order 164-176: VSSA and VSS ground pins; Pin Orientation = Bottom; Section = Ground.
Note: Ground is not in the current Section autocomplete list, but it was intentionally assigned to satisfy the ground-last requirement and was accepted by the property tool.

Follow-up items
  1. Change project Package or Case Code from TO to LQFP176 or 176-LQFP.
  2. Optionally update terminal Pin Type from datasheet classes (S, I, I/O, ANA) to improve ERC.
  3. Optionally populate Pin Description with Table 9 functions and key Table 10 alternate functions.
  4. Optionally change Part Type from Integrated Circuits to Microcontroller for clearer classification.
