STM32H743IIT6 Part Datasheet Audit
Audit date: 2026-07-07 Project part UID: 49e9010d-6e1e-43b5-af55-1199223a797e
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.
Fix metadata and verify
Fix package metadata
Populate pin metadata
Run component review
Check official footprint

| Pin count / terminals | 176 terminals | 176-pin LQFP package | Match |
| Package or Case Code | TO | LQFP176 / LQFP 24 x 24 mm, 0.5 mm pitch | Mismatch: should be 176-LQFP or LQFP176, not TO |

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 onRight;Section = Control. - Terminal Order 29-30: analog-only
PC2_CandPC3_C;Pin Orientation = Left;Section = Analog. - Terminal Order 31-163: bidirectional GPIO/peripheral interface pins; distributed
Leftfor datasheet pins 1-88 andRightfor datasheet pins 89-176 to keep the symbol balanced;Section = Interface. - Terminal Order 164-176:
VSSAandVSSground 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.Full terminal-order groups
