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 | A0 | input | Device address input bit 0. Hardwired to VCC or GND to set the I2C slave address; floats to logic low via an internal proprietary bias circuit. Allows up to 8 devices on the same bus. |+| 2 | A1 | input | Device address input bit 1. Hardwired to VCC or GND to set the I2C slave address; floats to logic low via an internal proprietary bias circuit. |+| 3 | A2 | input | Device address input bit 2. Hardwired to VCC or GND to set the I2C slave address; floats to logic low via an internal proprietary bias circuit. |+| 4 | GND | power_in | Ground reference (0 V). |+| 5 | SDA | bidirectional | Serial data line for the I2C-compatible 2-wire bus. Open-drain output, requires an external pull-up resistor; may be wire-ORed with any number of other open-drain or open-collector devices. |+| 6 | SCL | input | Serial clock input for the I2C-compatible 2-wire bus. Positive edge clocks data into the EEPROM; negative edge clocks data out. |+| 7 | WP | input | Write Protect. Tie to GND for normal read/write operation; tie to VCC to hardware-write-protect the entire array. |+| 8 | VCC | power_in | Power supply input, 1.7 V to 3.6 V (D-suffix low-voltage variant). Decouple locally with a 100 nF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Tudi |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `AT24C01D-SSHM-T-TUDI`+- `AT24C01D-SSHM-T-TUDIXHM-T`+- `AT24C01D-SSHM-T-TUDITH-T`+- `AT24C01D-SSHM-T-TUDIGT3-TUDI`+- `AT24C01D-SSHM-T-TUDIPUM-T`+- `AT24C01D-SSHM-T-TUDISTUM-T`++## CAD (KiCad official)++- Symbol: `AT24C01D-SSHM-T-TUDI`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Tudi datasheet](docs/at24c01d-sshm-t-tudi-datasheet.pdf) (18 pp, sha256 `ad7501132ec29638`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
