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-wire to GND or VCC to select the device address on a shared I2C bus (up to 8 devices). Internally pulled down to GND when floating; Microchip recommends always tying to a known state (pull-up resistor ≤10 kΩ if used). |+| 2 | A1 | input | Device address input bit 1. Hard-wire to GND or VCC for I2C bus device addressing (matches slave address bits). Internally pulled to GND if floating; tie to a known state for reliable operation. |+| 3 | A2 | input | Device address input bit 2. Hard-wire to GND or VCC for I2C bus device addressing. Internally pulled to GND if floating; recommended pull-up resistor value ≤10 kΩ. |+| 4 | GND | power_in | Ground reference for the power supply. Connect to system ground. |+| 5 | SDA | bidirectional | I2C serial data line. Open-drain bidirectional I/O; requires an external pull-up resistor (≤10 kΩ) to VCC. Wire-OR compatible with other open-drain devices on the same bus. |+| 6 | SCL | input | I2C serial clock input. Positive-edge clocks data into the device; negative-edge clocks data out. Supports 100 kHz Standard, 400 kHz Fast, and 1 MHz Fast Mode Plus (FM+) operation. |+| 7 | WP | input | Write-Protect input. When tied to VCC, all write operations to the memory array are inhibited (full array hardware write protection). When tied to GND or left floating (internal pull-down active), normal read/write operations are permitted. |+| 8 | VCC | power_in | Device power supply. Operating range 1.7V to 5.5V (2.5V to 5.5V for 1 MHz FM+ operation). Bypass with a 0.1 µF ceramic capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOT-23-5 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `AT24C02C-STUM-TSTUM-T`+- `AT24C02C-STUM-TPU`+- `AT24C02C-STUM-TSSHM`+- `AT24C02C-STUM-TTSSM`+- `AT24C02C-STUM-TMAHM`+- `AT24C02C-STUM-TXHM`++## CAD (KiCad official)++- Symbol: `AT24C02C-STUM-T`+- 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:** [Microchip datasheet](docs/at24c02c-stum-t-datasheet.pdf) (45 pp, sha256 `d8c3107c3c5a425e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
