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. Hard-wired to VCC or GND to set the chip's I2C slave address, allowing up to 8 devices on a single 2-wire bus. |+| 2 | A1 | input | Device address input bit 1. Hard-wired to VCC or GND to set the chip's I2C slave address. |+| 3 | A2 | input | Device address input bit 2. Hard-wired to VCC or GND to set the chip's I2C slave address. |+| 4 | GND | power_in | Ground reference (0 V) for the device. |+| 5 | SDA | bidirectional | I2C serial data line. Open-drain bidirectional pin; requires an external pull-up resistor to VCC. May be wire-ORed with any number of other open-drain or open-collector devices. |+| 6 | SCL | input | I2C serial clock input. Positive edge clocks data into the EEPROM, negative edge clocks data out. Requires an external pull-up resistor. |+| 7 | WP | input | Write Protect input. Tie to GND for normal read/write operations; tie to VCC to enable hardware write-protect of the full array. |+| 8 | VCC | power_in | Positive supply voltage input. Operating range 1.7 V to 5.5 V (WI variant compatible down to 1.8 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Tudi |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `CAT24C01WI-GT3-TUDI`+- `CAT24C01D-SSHM-T-TUDI`+- `CAT24C01C-SSHM-T-TUDI`+- `CAT24C01YI-GT3-TUDI`+- `CAT24C01D-XHM-T-TUDI`+- `CAT24C01C-XHM-T-TUDI`+- `CAT24C01B-TH-T-TUDI`+- `CAT24C01D-PUM-TUDI`+- `CAT24C01C-PUM-TUDI`+- `CAT24C01C-STUM-T-TUDI`+- `CAT24C01D-STUM-T-TUDI`++## CAD (KiCad official)++- Symbol: `CAT24C01WI-GT3-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/cat24c01wi-gt3-tudi-datasheet.pdf) (18 pp, sha256 `ad7501132ec29638`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
