Part Audit Review
Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
Thought for 9 sec
I’ll audit the part metadata and geometry, source the official Cypress/Infineon datasheet if needed, update the Datasheet property, then report any symbol, footprint, or pin-description mismatches.

Audit complete. The 8-pin symbol mapping and footprint geometry are consistent with the datasheet; key issues are missing package/type metadata, absent pin descriptions, and all pin electrical types being unspecified. A datasheet URL was already present, so it was not changed, though the legacy HTTP Cypress link should eventually be replaced by the official Infineon HTTPS PDF.

Table
| Field | Existing value | Review |
|---|---|---|
| MPN | CY15B102Q-SXE | Correct |
| Manufacturer | Infineon | Correct current manufacturer; description still says Cypress Semiconductor |
| Description | Cypress Semiconductor, CY15B102Q-SXE | Identifies the part but is too minimal and uses the legacy manufacturer name |
| Pin count | 8 | Correct |
| Designator prefix | IC | Reasonable |
| Datasheet URL | Cypress HTTP download URL | Present, so no update was required by the request; however it is insecure/legacy and should preferably be replaced with the official Infineon HTTPS PDF |
| Part Type | Empty | Missing |
| Package property | Not set | Missing; should identify PG-DSO-8 / 8-pin SOIC, 208-mil body, package drawing 001-85261 |

Pin Cross-Check
Table
| Pin | Datasheet signal | Existing terminal | Mapping | Existing pin metadata |
|---|---|---|---|---|
| 1 | /CS | ~CS | Correct | Pin Type is Unspecified; Pin Description missing |
| 2 | SO | SO | Correct | Pin Type is Unspecified; Pin Description missing |
| 3 | /WP | ~WP | Correct | Pin Type is Unspecified; Pin Description missing |
| 4 | VSS | VSS | Correct | Pin Type is Unspecified; Pin Description missing |
| 5 | SI | SI | Correct | Pin Type is Unspecified; Pin Description missing |
| 6 | SCK | SCK | Correct | Pin Type is Unspecified; Pin Description missing |
| 7 | /HOLD | ~HOLD | Correct | Pin Type is Unspecified; Pin Description missing |
| 8 | VDD | VDD | Correct | Pin Type is Unspecified; Pin Description missing |
The schematic symbol pin numbers and names match the datasheet. The active-low naming convention using
~ is acceptable. The symbol should be improved by setting electrical types: SCK, SI, /CS, /WP, and /HOLD as inputs; SO as output; VDD and VSS as power. Each terminal should also receive the datasheet-derived Pin Description.Footprint Cross-Check
- Eight pads are present.
- Pad numbering/order maps correctly to the datasheet pinout.
- Pad pitch is 1.27 mm.
- Pad row center spacing is approximately 7.35 mm, and pad size is approximately 0.65 x 1.65 mm, consistent with a practical land pattern for the wide 208-mil SOIC package.
- The datasheet supplies a package outline but no explicit recommended PCB land pattern. Therefore the footprint cannot be certified directly against a manufacturer land-pattern table, but its observed geometry is plausible and consistent with the package dimensions.
- Pin 1 orientation should remain verified visually against the footprint's pin-1 marker/3D model before release; the data inspection confirms mapping but not a clearly readable marker.
Mismatches and Quality Flags
- Missing Part Type — the property is blank; recommended value: F-RAM / Nonvolatile Memory.
- Missing package metadata — no Package or Case Code is set; recommended:
PG-DSO-8 / SOIC-8 208 mil (001-85261). - Missing pin descriptions — all terminals lack functional descriptions.
- Incorrectly unspecified pin electrical types — all pins are marked Unspecified, reducing ERC usefulness.
- Minimal/legacy description — should describe the device as a 2-Mbit automotive SPI F-RAM and use Infineon as current manufacturer, optionally noting Cypress legacy branding.
- Datasheet URL quality — a URL exists, so it was not changed under the user's condition; it is HTTP and legacy. The official Infineon HTTPS PDF above is the preferred replacement.
- Footprint evidence limitation — geometry appears appropriate, but the datasheet does not publish a recommended land pattern, so exact solder-land compliance cannot be proven solely from this datasheet.
Overall Assessment
The critical pin numbering, signal names, and footprint pad arrangement are consistent with the CY15B102Q-SXE datasheet. The main deficiencies are metadata completeness and ERC quality rather than a functional pinout error. No Datasheet property update was made because the property was already populated.
