HG24C32M from HGSEMI, in a SOIC-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 | E0 | input | Hardware device-address input that must match the E0 bit of the device address; if left floating it is internally pulled down to Vss. |
| 2 | E1 | input | Hardware device-address input that must match the E1 bit of the device address; if left floating it is internally pulled down to Vss. |
| 3 | E2 | input | Hardware device-address input that must match the E2 bit of the device address; if left floating it is internally pulled down to Vss. |
| 4 | Vss | power_in | Ground reference for the VCC supply voltage. |
| 5 | SDA | bidirectional | Open-drain serial data input and output that is normally pulled high by an external device and may be wire-OR'ed with other open-drain or open-collector devices. |
| 6 | SCL | input | Serial clock input that clocks data in on the positive edge and clocks data out on the negative edge. |
| 7 | WCB | input | Active-low write control: when connected to VCC all write operations are inhibited, when connected to Vss normal writes are allowed, and if left floating it is internally pulled down to Vss. |
| 8 | VCC | power_in | Supply voltage, specified at 1.7 V to 5.5 V in operation, with an absolute maximum range of -0.5 V to 6.5 V. |
