- Verified the official NXP datasheet source. The direct part-number URL was not the active NXP datasheet, but the official NXP document is IMXRT1170CEC Rev. 5, 01/2024 at https://www.nxp.com/docs/en/data-sheet/IMXRT1170CEC.pdf, and it explicitly covers MIMXRT1176DVMAA.
- Audited project metadata against the datasheet:
- MPN: MIMXRT1176DVMAA matches.
- Package: MAPBGA-289_L14.0-W14.0-R17-C17-P0.80-TL matches the datasheet package family: 289-pin MAPBGA, 14 mm x 14 mm, 0.8 mm pitch.
- Manufacturer: should be normalized to NXP Semiconductors.
- Part Type: should be Microcontroller or Crossover MCU, not a sourcing/category label.
- Datasheet URL: missing and should be set to the official NXP URL above.
- Description: missing and should summarize the part as a dual-core i.MX RT1170 crossover MCU with 1 GHz Arm Cortex-M7, 400 MHz Arm Cortex-M4, 2 MB SRAM, and the 289 MAPBGA package.
- Audited schematic terminal count against the datasheet ball map:
- Datasheet: 289-ball 17 x 17 MAPBGA.
- Project schematic: 289 terminal elements.
- Project layout: 289 pads and 1 footprint.
- Count-level alignment is good.
- Audited the official ball map:
- Datasheet Table 115 lists a full 17 x 17 ball map from rows A through U, skipping I/O-style row letters as expected for BGA notation.
- The observed project terminals match many sampled datasheet pin/ball pairs, including USB, MIPI, GPIO, power, clock, control, and ground pins.
- Audited footprint/package details:
- Datasheet mechanical package: SOT1534-4 / LFBGA289, 14 mm x 14 mm x 1.37 mm nominal body, 289 balls, 0.8 mm pitch, 17 x 17 array.
- Project layout has a matching 289-pad footprint at count level.
Success criteria review
| Criterion | Status | Notes |
|---|---|---|
| Datasheet URL property updated | ❌ Blocked | I identified the official URL, but the project is read-only for this session, so I could not write the property. |
| Metadata and properties match datasheet | ⚠️ Partially verified | MPN and package match. Manufacturer, part type, description, operating temperature, and datasheet URL need updates. |
| Schematic terminals fully synchronized | ⚠️ Partially verified | Terminal count matches 289, but terminal metadata is incomplete: observed terminals have Pin Type: Unspecified, Terminal Type: unspecified, and no populated short pin descriptions. The part-project sync guidance requires exact terminal count, exact pin numbers, and per-terminal properties such as pin type, pin description, section, pin group, orientation, and sub-symbol grouping . |
| NC/exposed pad handling confirmed | ⚠️ Needs follow-up | The datasheet ball map is complete at 289 balls. The extracted datasheet note says NC signals are no-connect if present, but I did not find separate exposed-pad terminals in the sampled package data. |
| Footprint corresponds to package | ⚠️ Count-level verified | Layout has 289 pads, matching the datasheet. Full geometry validation still needs pad pitch/diameter/body-outline comparison in an editable or exportable footprint environment. |
Required updates when edit access is available
| Area | Required value/action |
|---|---|
| Datasheet URL | https://www.nxp.com/docs/en/data-sheet/IMXRT1170CEC.pdf |
| Manufacturer Name | NXP Semiconductors |
| Part Type | Microcontroller or Crossover MCU |
| Description | Crossover MCU with Arm Cortex-M7/M4 cores, 1 GHz M7, 400 MHz M4, 2 MB SRAM, 289 MAPBGA 14 mm x 14 mm package |
| Operating Temperature | 0°C to +95°C junction |
| Operating Voltage | Use 3.6 V as the max recommended external I/O/supply-domain operating voltage field, with domain-specific rails documented separately. The sync guidance says Operating Voltage should use the maximum recommended operating voltage as a numeric field where applicable . |
| Terminal pin types | Populate from signal category: VSS/DCDC_GND = Ground; VDD*/NVCC*/VDDA*/DCDC_IN = Power In; DCDC_DIG/DCDC_ANA = Power Out or Power domain depending project convention; GPIO* = Bi-Directional; USB/MIPI/CLK/crystal/control pins by function. |
| Terminal descriptions | Add short 3-6 word functional labels, not long datasheet text, per the part sync guidance . |
| Section / Pin Group / Orientation / Sub-symbol | Add for all terminals. For a >20-pin MCU/SoC, each terminal should belong to a sub-symbol, with power and ground in a dedicated Power group, per the grouping guidance . |
I could not apply the metadata and terminal-property updates because this session does not have edit permission on the project. The audit identified the needed corrections and verified the count-level schematic and footprint alignment, but the write portion of the plan remains pending until edit access is granted.
