Existing properties
| Property | Current value | Assessment |
|---|---|---|
| Manufacturer Part Number | PIC32MZ2048EFM100-I/PT | Present |
| Manufacturer Name | Microchip | Present |
| Part Type | Integrated Circuits | Present but generic |
| Package or Case Code | 100-TQFP | Present but not very specific |
| Designator Prefix | IC | Present but nonstandard for MCU library parts |
| Datasheet URL | datasheetarchive mirror PDF | Present, so no update was required by your rule |
Table
| Spec | Datasheet value |
|---|---|
| Family | PIC32MZ Embedded Connectivity with Floating Point Unit (EF) Family |

Good news
| Check | Result |
|---|---|
| Terminal count | 100 terminals present |
| Pin numbers | All appear populated |
| Pin naming style | Pin labels appear aligned with datasheet muxed-function naming |
| Major package consistency | 100-symbol terminals and 100-footprint pads are consistent with the 100-pin TQFP datasheet package |
Problems found
| Issue | Severity | Notes |
|---|---|---|
All pin types are Unspecified | High | This weakens ERC usefulness and part quality |
No Pin Description fields | Medium | Pin intent is not documented |
No Section fields | Medium | Makes a large MCU symbol harder to organize |
No Pin Group fields | Medium | Interface grouping is missing |
No Pin Orientation fields | Medium | Symbol readability is not curated |
No Sub-symbol Designator Suffix fields | Medium | For a 100-pin MCU, lack of sub-symbol grouping makes the symbol harder to use |
| Datasheet URL is not an official vendor URL | Low | It works, but it is a mirror, not clearly canonical |
Designator Prefix is IC | Low | For MCU library hygiene, U is usually a better fit |
Package code is only 100-TQFP | Low | Datasheet is more specific: 100-Lead TQFP, 12 x 12 x 1 mm |
Footprint audit
| Check | Result |
|---|---|
| Footprint pad count | 100 pads |
| Exposed pad | None found |
| Datasheet expectation | 100-lead perimeter TQFP, no exposed pad indicated for this package |
| Overall assessment | Footprint appears consistent with the datasheet package class |
Table
| Item | Current | Datasheet / expected | Flag |
|---|---|---|---|
| Pin Type | All Unspecified | Should be classified per pin function | Mismatch |
| Pin Description | Missing | Should have short functional descriptions | Missing |
| Section | Missing | Should group Power, Ground, GPIO, Analog, Clock, Debug, etc. | Missing |
| Pin Group | Missing | Should group ports/interfaces | Missing |
| Pin Orientation | Missing | Should be set for readable symbol use | Missing |
| Sub-symbol grouping | Missing | Recommended for a 100-pin MCU | Missing |
| Package or Case Code | 100-TQFP | Better as 100-Lead TQFP (12x12x1 mm) or equivalent canonical code | Incomplete |
| Designator Prefix | IC | U is more standard for MCU parts | Incomplete |
| Datasheet URL | Mirror URL | Official Microchip PDF preferred | Advisory |
- pin count matches the package
- footprint pad count matches the symbol
- package class matches the datasheet
- all pin types are unspecified
- no pin descriptions
- no functional grouping
- no sub-symbol organization
