Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | SCL | input | Serial clock input. Used to positive-edge clock data into the EEPROM and negative-edge clock data out. Schmitt-triggered, open-drain bus line; requires an external pull-up resistor. |+| 2 | GND | power_in | Ground reference (0 V) for the device. |+| 3 | SDA | bidirectional | Serial data I/O. Bi-directional, open-drain; may be wire-ORed with other open-drain/open-collector devices. Requires an external pull-up resistor to VCC. |+| 4 | VCC | power_in | Positive supply input. Operating range 1.7 V to 5.5 V (D-variant tolerates up to 5.5 V, compatible down to 1.8 V). |+| 5 | WP | input | Write protect input. Tie to GND for normal read/write; tie to VCC to hardware-write-protect the full array. Internally biased low if left floating. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Tudi |+| Package | SOT-23-5 |+| Category | Memory |+| Pins | 5 |++## Ordering variants++- `AT24C01D-STUM-T-TUDI`+- `AT24C01D-STUM-T-TUDISSHM-T-TUDI`+- `AT24C01D-STUM-T-TUDIXHM-T-TUDI`+- `AT24C01D-STUM-T-TUDITH-T-TUDI`+- `AT24C01D-STUM-T-TUDIGT3-TUDI`+- `AT24C01D-STUM-T-TUDIPUM-TUDI`++## CAD (KiCad official)++- Symbol: `AT24C01D-STUM-T-TUDI`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Tudi datasheet](docs/at24c01d-stum-t-tudi-datasheet.pdf) (18 pp, sha256 `ad7501132ec29638`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
