Tudi · EEPROM · SOT-23-5
AT24C02C-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 EEPROM 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, normally pulled high by an external device and wire-ORable with other open-drain or open-collector devices; data may change only while SCL is low. |
| 4 | VCC | power_in | Power supply: 1.7 V to 5.5 V at 400 kHz, or 2.5 V to 5.5 V at 1 MHz. |
| 5 | WP | input | Write protect: tying to GND allows normal read/write operation, while tying to VCC enables hardware write protection of the full array. |
