24LC01B-I from Tudi, in a DIP-8. 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 | A0 | input | Device address input hardwired to select the device address bit; the datasheet states that the pin is biased to logic low internally if left floating. |
| 2 | A1 | input | Device address input hardwired to select the device address bit; the datasheet states that the pin is biased to logic low internally if left floating. |
| 3 | A2 | input | Device address input hardwired to select the device address bit; the datasheet states that the pin is biased to logic low internally if left floating. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Open-drain serial data pin that may be wire-ORed with other open-drain or open-collector devices; data may change only while SCL is low. |
| 6 | SCL | input | Serial clock input; data is clocked into the device on the SCL rising edge and out of the device on the falling edge. |
| 7 | WP | input | Write protect pin: connecting it to GND allows normal read/write operations, while connecting it to VCC enables hardware write protection of the full array. |
| 8 | VCC | power_in | Power supply, 1.7 V to 5.5 V for operation at 400 kHz and 2.5 V to 5.5 V for operation at 1 MHz. |
