AT24C02D-STUM-T-TUDI from Tudi, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCL | input | Serial clock input: data is positive-edge clocked into the device and negative-edge clocked out of it. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | SDA | bidirectional | Bidirectional open-drain serial data pin that may be wire-ORed with any number of other open-drain or open-collector devices. |
| 4 | VCC | power_in | Power supply; the datasheet specifies VCC of 1.7 V to 5.5 V at 400 kHz and 2.5 V to 5.5 V at 1 MHz. |
| 5 | WP | input | Write Protect: connecting to GND allows normal read/write operation, while connecting to VCC enables hardware write protection of the full array. |
