AT24C04CN from HGSEMI, 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 | NC | unconnected | No connect; the DIP-8 pin configuration shows pin 1 as NC. |
| 2 | E1 | input | Device address input that can be tied to VCC or GND in any combination, and is internally pulled down to GND if left floating. |
| 3 | E2 | input | Device address input that can be tied to VCC or GND in any combination, and is internally pulled down to GND if left floating. |
| 4 | GND | power_in | Ground reference for the power supply, to be connected to system ground. |
| 5 | SDA | bidirectional | Serial data, an open-drain bidirectional input/output pin used to transfer data to and from the device. |
| 6 | SCL | input | Serial clock input that controls data flow; input data is latched on the rising edge of SCL and output data is clocked out on the falling edge. |
| 7 | WP | input | Write protection input; tied to VCC it makes the whole memory read-only, tied to GND it enables writes, and it is internally pulled down to GND if left floating. |
| 8 | VCC | power_in | Device power supply, 1.7V to 5.5V; operation at invalid VCC voltages may produce spurious results. |
