1. Executive Summary
This project cleans up the existing NXP MIMX8MM6CVTKZAA part project by applying datasheet-driven terminal normalization. The cleanup standard uses datasheet signal names as terminal designators, ball coordinates in the
Pin Number property, and enriched terminal metadata for control, power, JTAG, reset, boot, and analog functions. The same pass also records explicit pin behavior tags where the datasheet specifies open-drain, pull-up, or pull-down behavior.2. Goals and Non-Goals

3. System Overview
This is a part-project data cleanup effort for the NXP i.MX 8M Mini industrial applications processor in FCBGA486 package. Each project component represents one terminal entry of the device package, and the goal is to make the part project internally consistent, easier to audit against the datasheet, and safer to reuse in schematic designs.

4. Requirements
The part project must reflect the datasheet as the single source of truth for terminal identity and metadata.
4.1 Functional Requirements
- Terminal designator must use the datasheet signal name.
Pin Numbermust retain the datasheet ball coordinate.- Control, power, JTAG, reset, boot, and analog terminals must have a populated
Pin Description. - Pins with datasheet-specified open-drain or pull-up or pull-down behavior must be explicitly tagged in terminal metadata.
4.2 Electrical Requirements
- Power and ground terminals must carry explicit power-reference descriptions.
- Clock, reset, and boot-strap terminals must preserve their datasheet electrical direction and internal pull state where specified.
- Analog terminals must preserve datasheet analog function notes and any external connection guidance explicitly stated in the datasheet.
4.3 Environmental and Reliability Requirements
Operating ranges, expected lifetime, handling constraints, safety/compliance.

5. Constraints
Hard limits that shape the design choices.
...
5.1 Mechanical Constraints
Size, mounting, connector access, enclosure interactions.
...
5.2 Power and Thermal Constraints
Power source limits, dissipation ceilings, heat-sensitive components.
...
5.3 Layout / Implementation Constraints
High-level layout rules (keepouts, grounding intent, routing classes), without detailed PCB guidance.
...
5.4 Cost and Sourcing Constraints
Target cost range, availability requirements, preferred vendors/alternates policy.
...
6. Assumptions and Dependencies
What we assume is true, and what the design depends on (parts, standards, external systems).
...
7. Validation Criteria
The cleanup pass is accepted when the project reflects a single naming convention, the targeted functional terminal families have datasheet-based descriptions, and open-drain or pull-state behavior is explicitly captured where specified.
7.1 Acceptance Tests
- All visible reversed-name terminals are renamed to their datasheet signal names.
- Sampled targeted terminals for control, reset, JTAG, boot, power, and analog functions include populated
Pin Descriptionmetadata. Pin Behaviormetadata is present on terminals whose datasheet entry explicitly states open-drain, pull-up, or pull-down behavior.
7.2 Review Checklist
- Confirm signal-name designators and ball-coordinate
Pin Numberproperties are paired consistently. - Confirm no targeted terminal retains an ambiguous or missing electrical role after cleanup.
- Document any remaining inaccessible or unverified terminals as explicit exceptions.
