Part Datasheet and Metadata Review
Thought for 3 mins 36 sec
Here’s the requested review, executed in order.
Step 1 — Review available part information
- Part: MIMXRT1176DVMAA
- MPN: MIMXRT1176DVMAA
- Designator prefix: U
- Pin count (symbol/footprint): 289 balls (library metadata)
- Package (library metadata): MAPBGA-289_L14.0-W14.0-R17-C17-P0.80-TL
- Grid: 17 × 17
- Ball pitch: 0.80 mm
- Body size: 14.0 × 14.0 mm
- Schematic symbol present: yes (ball labels A..U rows with numeric 1..17, modeled as Terminal pins)
- Footprint present: yes (pads for each signal; 1:1 naming with symbol)
Step 2 — Datasheet URL
- Datasheet property on the part: not set.
- Attempted to locate official datasheet via web search, but the web tool returned no results. I cannot add the ‘Datasheet’ property without a valid URL.
- Action needed: please share the official datasheet link (PDF or NXP product page) and I will immediately attach it to the part and proceed with full extraction.
Step 3 — Datasheet scan and metadata extraction
- Blocked until a datasheet URL is available. Once provided, I will extract and summarize:
- Absolute Maximum Ratings
- Recommended Operating Conditions
- Electrical Characteristics
- Pin descriptions
- Package dimensions/land pattern
- Special/Key features
Step 4 — Cross-check of symbol and footprint vs datasheet (preliminary, without datasheet)
What matches so far
- Ball grid/pinout scheme: The symbol implements per-ball terminals with alphanumeric labels (e.g., VSS shows Pin Number A1), consistent with a 17×17 BGA.
- Pin coverage: The PCB footprint includes a pad for each symbol Terminal (1:1 mapping by name), indicating intended completeness.
Issues and risks to address after datasheet review
- Pin electrical types:
- Many ground balls are typed as “Power Out” (e.g., VSS). This is likely incorrect and can cause ERC confusion; these should be typed as “Ground” (or “Power In” per convention) per datasheet guidance.
- Several functional pins are “Unspecified” (examples: USB1_VBUS, USB2_DN, USB1_DN, MIPI_DSI_DP0, POR_B). These should be set to Input/Output/Bi-Directional/Power In as specified by the datasheet.
- Footprint verification items pending datasheet:
- Confirm body size (14 × 14 mm), ball pitch (0.80 mm), ball diameter, and keep-out recommendations.
- Confirm corner orientation (A1) indicator and silkscreen/fab markers.
- Confirm solder mask and paste apertures vs NXP recommended land pattern.
- Confirm any depopulated balls or NCs per MPN variant.
- Ordering/manufacturing risk without datasheet:
- Family-level documents sometimes have multiple package variants and tolerance notes that affect paste and assembly. Without confirming these, there is risk of assembly defects or misordered parts.
Next step
- Share the official NXP datasheet URL for MIMXRT1176DVMAA. I’ll immediately:
- Attach it to the part (“Datasheet” property).
- Extract all required metadata into concise tables.
- Complete a definitive symbol/footprint cross-check against the datasheet’s pin tables and mechanical package section.
