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 | I2C Serial Clock input. Positive edge clocks data in and negative edge clocks data out. Schmitt-trigger, noise-filtered input. Requires an external pull-up to VCC (typically 1.3 kΩ at 2.5-5.5 V, 10 kΩ at 1.7 V). |+| 2 | Vss | power_in | Ground reference for the VCC supply. |+| 3 | SDA | bidirectional | I2C Serial Data input/output. Open-drain, may be wire-OR'ed with other open-drain devices. Requires an external pull-up to VCC. Data out has VOL ≤ 0.4 V @ IOL = 2.1 mA (VCC = 3.0 V). |+| 4 | Vcc | power_in | Supply voltage. Operating range 1.7 V to 5.5 V. Standby current ≤ 1 µA @ 3.3 V, ≤ 3 µA @ 5.5 V. Absolute maximum 6.5 V. |+| 5 | WCB | input | Write Control input, active low. Tie to VSS (or leave floating; internal pull-down to VSS) to allow normal write operations. Tie to VCC to inhibit all write operations and write-protect the entire memory array. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOT-23-5 |+| Category | Memory |+| Pins | 5 |++## Ordering variants++- `AT24C02M5/TR`+- `AT24C02M5N`+- `AT24C02M5M/TR`+- `AT24C02M5M-4K/TR`+- `AT24C02M5MM/TR`+- `AT24C02M5MT/TR`+- `AT24C02M5DQ3/TR`+- `AT24C02M5DQ2/TR`++## CAD (KiCad official)++- Symbol: `AT24C02M5`+- 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:** [HGSEMI datasheet](docs/at24c02m5-datasheet.pdf) (None pp, sha256 `14a1ed1066ebdfb3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
