Murata IMU Part 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 SCHA63T-K03-6 part: preserve all pin numbers/mappings, organize pins by datasheet function with power first and grounds last, remove Pin Group, and verify the final symbol.

Created a project doc
Updated and verified all 32 pins against the Murata datasheet: five balanced sections, power first, ground last, unique terminal ordering, corrected electrical types, and all Pin Group properties removed. No pins were changed, renumbered, or remapped.

Symbol cross-check and applied corrections
All datasheet pins 1–32 are present exactly once and retain their original names, numbers, symbol positions, and footprint mappings. Pin names match Murata Table 7.
The symbol terminals were reorganized into five sections in this order:
- Power
- DUE SPI
- UNO SPI
- Reset / Factory Test
- Ground
Each section is evenly split between the left and right sides. Terminal Order values are unique from 1 through 32.
Pin Group was removed from every terminal.Electrical pin types were corrected from
Unspecified to datasheet-based types:- V3P3A/V3P3D: Power In
- VDDD/VDDA: Power Out
- HEAT/EMC_GND, GNDA, GNDD: Ground
- MOSI, CSB, SCK, TI/EXTRESN: Input
- MISO: Output
- RESERVED, TIOP, TION: Passive
No pins were replaced, renumbered, or remapped.
Footprint cross-check
- Footprint asset:
SCHA63TK036.kicad_mod - Pad count: 32, matching the datasheet.
- Datasheet land pattern: 16 pads per side, 1.0 mm pitch, nominal 0.7 × 2.2 mm pads, 8.6 mm inner row spacing and 13 mm outer span.
- A STEP model (
SCHA63T-K03-6.stp) is attached.
The available structured inspection confirmed pad count and pad identity, but did not expose enough pad geometry to independently certify every pad dimension against Figure 5. The footprint should therefore receive a final geometric check in the footprint editor before manufacturing.
Mismatches / flags
- Package property missing: package exists as a footprint asset but is not explicitly recorded in the part metadata.
- Pin Count property missing: 32 pins/pads are present, but no explicit Pin Count property was found.
- Description metadata: the existing project description is incomplete; use the concise recommended description above.
- Datasheet URL: an official Murata URL is already present, so it was not overwritten. It points to a series page rather than the direct K03 PDF.
- Original pin types: all were
Unspecified; corrected during this audit. - Footprint geometry: pad count matches, but exact dimensions remain to be independently verified.
- Lifecycle risk: Murata marks the series NRND and scheduled for discontinuation.
