Part Metadata Review and Update
Thought for 2 mins 6 sec
I reviewed the current part project against the datasheet workflow: verify the existing datasheet URL first, then compare metadata, pin count, symbol pins, and footprint/pad mapping to the datasheet as the source of truth
Result
- Datasheet URL already exists, so no web search or property update was needed.
- Pin count matches: the project has 8 terminal components, and the datasheet’s SOP8 package also has 8 pins.
- Symbol-to-footprint pad mapping appears consistent for all 8 pins.
- I found a few metadata/property issues and missing pin-detail fields worth fixing.
Table
| Field | In project | Datasheet / evidence | Status |
|---|---|---|---|
| Description | NOR Flash | Serial NOR flash, 128 Mbit / 16 MByte, standard/dual/quad SPI | Needs improvement |
| Manufacturer Name | GigaDevice Semiconductor (HK) Limited | GigaDevice | Acceptable |
| Manufacturer Part Number | GD25WQ128ESIGR | Datasheet identifies GD25WQ128ESIG as the listed SOP8 industrial option; ...R parses like reel packing but is not explicitly listed in the valid ordering table | Possible mismatch / ambiguity |
| Part Type | Integrated Circuits | More specific: SPI NOR Flash | Too generic |
| Designator Prefix | IC | IC-type part, so this is fine | OK |
| Datasheet URL | Set | Official datasheet content was retrievable from the existing URL | OK |
| Package / Case Code | Not shown in project context | SOP8 208 mil, 8 leads, 1.27 mm pitch, body approx. 7.90 mm x 5.28 mm nominal | Missing / should be populated if absent |
Table
| Spec | Value |
|---|---|
| Memory type | SPI NOR Flash / Uniform Sector Dual and Quad Serial Flash |
| Density | 128 Mbit |
| Capacity | 16 MByte |
| Organization | 16M x 8 |
| Interface | Standard SPI, Dual SPI, Quad SPI |
| Supply voltage | 1.65 V to 3.6 V |
| Temperature range | -40 C to +85 C for the I grade |
| Max fast-read clock | 104 MHz at 2.3 V to 3.6 V |
| Package | SOP8 208 mil |
| Lead count | 8 |
| Pitch | 1.27 mm |
The project contains these 8 terminal components:
Datasheet pin table
Table
- Pin numbers are correct for all 8 terminals.
- Terminal names match the datasheet well, with only formatting differences like underscores and parentheses.
- All current Pin Type properties are
Unspecifiedon every terminal. That is incomplete for a part project and should be assigned from datasheet function mapping - I do not see
Pin Descriptionproperties on the terminals, so those appear missing. - For a simple 8-pin IC, one symbol block is fine; no sub-symbol split is needed
Table
I’m calling the IO1/IO2/IO3 pins Bi-Directional because the datasheet labels them as data input/output lines in dual/quad modes, even though their legacy single-bit functions are output/input/control.
Footprint check
The layout contains a footprint asset named
Footprint comparison
SOIC127P790X216-8N.kicad_mod with 8 pads mapped to the 8 terminal IDs.Table
| Check item | Datasheet | Footprint/layout | Status |
|---|---|---|---|
| Package family | SOP8 208 mil | SOIC-style 8-pin wide-body footprint | Likely compatible |
| Pin count | 8 | 8 pads | Match |
| Pitch | 1.27 mm | 127P implies 1.27 mm pitch | Match |
| Body width | Nominal 7.90 mm overall width E, body E1 nominal **5.28 mm` | 790 naming suggests 7.90 mm overall width | Match |
| Height | Max 2.16 mm | 216 naming suggests 2.16 mm | Match |
- Although the datasheet calls it SOP8 208 mil and the footprint filename uses SOIC, the dimensions look consistent with the datasheet package.
- Pad-to-terminal naming also matches:
Table
| Item | Issue |
|---|---|
| Pin Types | All 8 terminals are currently Unspecified |
| Pin Descriptions | Missing for all terminals |
| Description | NOR Flash is too generic and omits key searchable specs |
| Part Type | Integrated Circuits is too broad; SPI NOR Flash would be more useful |
| Package property | If Package or Case Code is not already set, it should be populated as SOP8 208MIL |
Table
| Item | Issue |
|---|---|
| MPN | Project uses GD25WQ128ESIGR, while the datasheet’s valid ordering table explicitly lists GD25WQ128ESIG for SOP8/I-grade. The datasheet separately explains R as reel packing, so this may be a legitimate packaging suffix, but it is not shown explicitly in the valid part-number list I retrieved. I’d flag this for manual confirmation. |
A better project description would be something like:
- 128 Mbit SPI NOR Flash memory, 16 MByte, 1.65 V to 3.6 V, standard/dual/quad SPI, SOP8 208 mil
- Symbol pin count and numbering: good
- Symbol names: good
- Footprint package geometry: looks correct for the datasheet package
- Footprint pad mapping: good
- Metadata completeness: partially incomplete
- Main issues: missing pin types, missing pin descriptions, overly generic description/part type, and a possible MPN suffix ambiguity
If you want, I can next update the part project properties and terminal properties to fill in the missing pin types/descriptions and tighten the metadata.
