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 | Serial Clock input. Provides the clock for the 2-wire I2C-compatible interface; command/input data on SDA is latched on the rising edge of SCL and output data is clocked out on the falling edge. Schmitt-trigger filtered input. |+| 2 | GND | power_in | Ground reference for the power supply. Connect to the system ground. |+| 3 | SDA | bidirectional | Serial Data. Open-drain bidirectional I/O used to transfer address, command and data bytes to/from the device. Requires an external pull-up resistor to VCC. |+| 4 | VCC | power_in | Device power supply, 1.7 V to 5.5 V. Bypass with a local decoupling capacitor. Operation at invalid VCC levels may produce spurious results. |+| 5 | WP | input | Write Protect. When tied to VCC the whole memory array (and Identification Page) becomes read-only; when tied to GND write operations are enabled. If left floating the pin is internally pulled down to GND. When driven high, device/word address bytes are still ACKed but data bytes are not. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOT23-5 |+| Category | Memory |+| Pins | 5 |++## Ordering variants++- `AT24C02CM5CM5/TR`+- `AT24C02CM5CN`+- `AT24C02CM5CM/TR`+- `AT24C02CM5CMM/TR`+- `AT24C02CM5CMT/TR`+- `AT24C02CM5CDQ/TR`++## CAD (KiCad official)++- Symbol: `AT24C02CM5`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/at24c02cm5-datasheet.pdf) (27 pp, sha256 `5143baf87225b7f3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
