Part Information Review and Verification
Worked for 1 min 19 sec
Pin metadata is updated; I’m now confirming the vendor datasheet URL and applying it if the part metadata is editable through the current tools.
Worked for 1 min 28 sec
Verified the pin metadata and Microchip datasheet URL; I’m running ERC/DRC now.
Worked for 1 min 23 sec
Updated the terminal pin types/descriptions and set the Datasheet URL to the Microchip-hosted PDF:
https://ww1.microchip.com/downloads/en/DeviceDoc/atmel-8700-seeprom-at24c01c-02c-datasheet.pdf.Open items
- ERC/DRC ran successfully at
2026-07-08T18:11:13.779Z; no errors, warnings, or open issues were returned. - The project-level Datasheet URL property is marked non-standard by Flux metadata tooling, but it is present and verified in the part project properties.
Suggested next steps
- Optionally update the part classification from broad “Integrated Circuits” to a more specific EEPROM/memory category if available.
- Re-run part review checks after publishing or library re-indexing to confirm the metadata propagates cleanly.

Part Information Review: AT24C02C-SSHM-T
Date: 2026-07-08
Scope
Reviewed available project part metadata, symbol terminals, footprint data, and datasheet-extracted specifications for the Microchip AT24C02C-SSHM-T part project.
Existing Part Information in Project
Table
| Field | Project Value | Review |
|---|---|---|
| Manufacturer Part Number | AT24C02C-SSHM-T | Matches datasheet/order code. |
| Manufacturer Name | Microchip | Correct for current branding of former Atmel part family. |
| Description | EEPROM | Correct but terse. Recommend expanding to “2-Kbit I2C serial EEPROM, 256 x 8, 1.7–5.5 V, SOIC-8”. |
| Part Type | Integrated Circuits | Broad but acceptable; should ideally be Memory / EEPROM if a more specific classification is available. |
| Datasheet URL | https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/0eed00b521d0c5e54a4242ca31ee4661bae33dd47b0980843a9ce240c34270a8.pdf | Already set, so no URL update was required by the request. The extracted PDF content matches the official AT24C01C/02C datasheet content. |
| Designator Prefix | IC | Appropriate. |
| Terminal / pad count | 8 | Correct for AT24C02C-SSHM-T 8S1 SOIC package. |
Note: Flux library search for the same UID also surfaced a Datasheet URL indexed as
https://componentsearchengine.com/Datasheets/2/AT24C02C-SSHM-T.pdf and type-specific metadata of Logic / AND. The current project properties inspected directly do not show those Logic / AND fields, but if present in hidden/indexed metadata they should be corrected because this part is an EEPROM, not a logic gate.Datasheet Identity and Ordering Information

Pinout Cross-Check
Table
| Pin | Project Terminal | Datasheet Function | Datasheet Type | Project Type | Result |
|---|---|---|---|---|---|
| 1 | A0 | Address input | Input | Unspecified | Pin number/name match; type missing. |
| 2 | A1 | Address input | Input | Unspecified | Pin number/name match; type missing. |
| 3 | A2 | Address input | Input | Unspecified | Pin number/name match; type missing. |

Symbol Review
The schematic symbol exposes the correct eight terminals with correct terminal names and pin numbers:
- Pin 1: A0
- Pin 2: A1
- Pin 3: A2
- Pin 4: GND
- Pin 5: SDA
- Pin 6: SCL
- Pin 7: WP
- Pin 8: VCC
No pin-number mismatch was found. The main symbol issue is metadata completeness: all terminal Pin Type values are currently
Unspecified, and datasheet-derived Pin Description fields are not populated.Footprint Review
Existing footprint asset:
SOIC127P600X175-8N.kicad_modObserved footprint data:
- 8 SMD pads.
- 1.27 mm pad pitch.
- Pad size approximately 0.65 mm x 1.525 mm.
- Pad centers: pins 1–4 on one side, pins 5–8 on the opposite side.
- Pin 1 chamfer / marker geometry is present in fab/silkscreen data.
- Footprint name decodes as SOIC, 1.27 mm pitch, approximately 6.00 mm lead span, 1.75 mm height, 8 narrow pins.
Datasheet package data for 8S1:
Table
| Dimension | Datasheet Value |
|---|---|
| Package | 8S1, 8-lead JEDEC SOIC |
| Body length D | 4.80 mm to 5.05 mm |
| Body width E1 | 3.81 mm to 3.99 mm |
| Lead span E | 5.79 mm to 6.20 mm |
| Pitch e | 1.27 mm BSC |
| Height A | 1.35 mm to 1.75 mm |
Result: The footprint appears compatible with Microchip 8S1 JEDEC SOIC-8. No clear footprint/package mismatch was found. As with any generic JEDEC footprint, final manufacturing confidence depends on verifying the exact land pattern against the manufacturer’s package drawing and the assembler’s soldering rules.
Mismatches and Improvements Flagged
- Pin types missing: All eight symbol terminals are
Unspecified. They should be assigned from the datasheet: A0/A1/A2/SCL/WP = Input, SDA = bidirectional/open-drain, VCC = Power, GND = Ground/Power. - Pin descriptions missing: Datasheet pin descriptions should be added for all pins.
- Description is too terse: “EEPROM” is correct but not very useful for search/BOM review. Recommend adding density, interface, voltage range, and package.
- Part classification is broad: “Integrated Circuits” is acceptable but should ideally be Memory / EEPROM / I2C Serial EEPROM if supported.
- Possible indexed metadata error: Library search surfaced Logic / AND type-specific metadata for this UID. That is wrong for AT24C02C-SSHM-T and should be corrected if present in editable hidden/type-specific fields.
- Datasheet URL note: A Datasheet URL was already present in the project, so no update was required. The current URL is an uploaded PDF rather than a vendor-domain URL; replace it with a Microchip-hosted URL if strict source-domain traceability is required.
Recommended Property Updates
Suggested concise pin descriptions:
Table
| Pin | Name | Suggested Pin Type | Suggested Pin Description |
|---|---|---|---|
| 1 | A0 | Input | Device address input bit A0; must match I2C device address bit. |
| 2 | A1 | Input | Device address input bit A1; must match I2C device address bit. |
| 3 | A2 | Input | Device address input bit A2; must match I2C device address bit. |
| 4 | GND | Ground | Ground reference for device power supply. |
| 5 | SDA | Bi-Directional | I2C serial data input/output; open-drain bus pin requiring pull-up. |
| 6 | SCL | Input | I2C serial clock input. |
| 7 | WP | Input | Write-protect input; GND/floating allows writes, VCC/high protects full array. |
| 8 | VCC | Power In | Device power supply, recommended 1.7 V to 5.5 V. |
Suggested part description:
2-Kbit I2C serial EEPROM, 256 x 8, 1.7–5.5 V, industrial temperature, SOIC-8.
Overall Result
The pinout and footprint are consistent with the datasheet for AT24C02C-SSHM-T. The main issues are metadata quality/completeness rather than functional symbol or footprint errors.
