# AT24C01D-STUM-T-TUDI

**Tudi** · EEPROM · SOT-23-5

AT24C01D-STUM-T-TUDI from Tudi, in a SOT-23-5. 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. Used to positive-edge clock data into the EEPROM and negative-edge clock data out. Schmitt-triggered, open-drain bus line; requires an external pull-up resistor. |
| 2 | GND | power_in | Ground reference (0 V) for the device. |
| 3 | SDA | bidirectional | Serial data I/O. Bi-directional, open-drain; may be wire-ORed with other open-drain/open-collector devices. Requires an external pull-up resistor to VCC. |
| 4 | VCC | power_in | Positive supply input. Operating range 1.7 V to 5.5 V (D-variant tolerates up to 5.5 V, compatible down to 1.8 V). |
| 5 | WP | input | Write protect input. Tie to GND for normal read/write; tie to VCC to hardware-write-protect the full array. Internally biased low if left floating. |
