HG24C512N 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 | A0 | input | Device/page address input that must match its hardwired level to select one of up to four devices on the bus; if left unconnected it defaults to zero. |
| 2 | A1 | input | Device address input that must match its hardwired level to select one of up to four devices on the bus; if left unconnected it defaults to zero. |
| 3 | NC | unconnected | No connect; the pin is not connected internally. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Open-drain serial data pin for bidirectional transfer that is normally pulled high by an external device and may be wire-ORed with other open-drain devices. |
| 6 | SCL | input | Serial clock input: data is clocked into the device on the positive edge and clocked out on the negative edge, with Schmitt-trigger filtered inputs. |
| 7 | WP | input | Write protect: tying it to GND allows normal writes, tying it to VCC inhibits all write operations, and it is internally pulled down to GND if left unconnected. |
| 8 | VCC | power_in | Supply voltage; the datasheet gives 1.8 V to 3.6 V, 2.7 V to 5.5 V, or 4.5 V to 5.5 V depending on the version. |
