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 least-significant bit of the I2C slave address, allowing up to 8 devices on one bus. Internal biasing pulls the pin toward logic low if left floating, but tying to a defined level is recommended. |+| 2 | A1 | input | Device address input bit 1. Hardwired to VCC or GND to set bit 1 of the I2C slave address. Internal proprietary bias defaults the pin low if floated. |+| 3 | A2 | input | Device address input bit 2. Hardwired to VCC or GND to set the most-significant of the 3 device-address bits (bits form '1010 A2 A1 A0 R/W'). Internal proprietary bias defaults the pin low if floated. |+| 4 | GND | power_in | Ground reference (0 V) for the device supply and I/O signals. |+| 5 | SDA | bidirectional | I2C serial data line. Open-drain bidirectional pin used for address and data transfer; requires an external pull-up resistor to VCC and may be wire-ORed with other open-drain devices. Input/output capacitance ≤8 pF. |+| 6 | SCL | input | I2C serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Maximum clock frequency is 1 MHz (VCC ≥ 2.5 V) or 400 kHz (VCC ≥ 1.7 V). Input capacitance ≤6 pF. |+| 7 | WP | input | Write protect input. Tie to GND for normal read/write operation; tie to VCC to write-protect the entire 1K array in hardware. |+| 8 | VCC | power_in | Positive supply voltage. Operating range 1.7 V to 5.5 V @ 400 kHz, or 2.5 V to 5.5 V @ 1 MHz. Typical standby current ISB ≈ 30 nA; read/write currents 0.14 mA / 0.28 mA typical at 5 V, 400 kHz. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Tudi |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `AT24C01C-SSHM-T-TUDI`+- `AT24C01C-SSHM-T-TUDIXHM-T`+- `AT24C01C-SSHM-T-TUDIPUM`+- `AT24C01C-SSHM-T-TUDISTUM-T`++## CAD (KiCad official)++- Symbol: `AT24C01C-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/at24c01c-sshm-t-tudi-datasheet.pdf) (None pp, sha256 `ad7501132ec29638`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
