STM32C031 Datasheet Audit


Check this 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. Remove the Pin Group property from all pins if it exists. Place Power pins first and Ground pins last. Within each section, distribute the pins as evenly as possible between the left and right sides; for example, split 10 pins as 5/5 and 11 pins as 5/6 or 6/5. If a section contains only one pin, leave it on the most appropriate side. Keep the symbol compact, balanced, and visually symmetrical. If a pin function is unclear, assign Unclear / Check datasheet, then apply all changes directly to the schematic component.
I’ll apply this to the current MPN, STM32C031K6T6. I’ll preserve every pin number and mapping, remove Pin Group, assign datasheet-based sections/types/orientations/orders, and rebalance the symbol with power first and ground last.

Updated the official datasheet URL and reorganized all 32 symbol pins without changing names, numbers, or mappings. Pins are balanced 16/16 left/right, Power is first, Ground last, and all Pin Group properties were removed.
The Part Datasheet Audit contains the full findings. Critical issue: the LQFP32 footprint appears scaled approximately 1000× too small; incorrect Logic/AND classification and missing package metadata were also flagged. An internal part-quality report was filed.
I checked the official datasheet, and everything is correct, taking into account that the dimensions are specified in millimeters, not meters.
You’re correct—the footprint values are stored in meters, so 0.0008 m = 0.80 mm; there is no 1000× scaling error. I corrected the Part Datasheet Audit and withdrew the fabrication-blocking warning.
