SD3010 from WAVE, in a SOP-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 connection; the datasheet pin drawing labels pin 1 as NC. |
| 2 | NC | unconnected | No connection; the datasheet pin drawing labels pin 2 as NC. |
| 3 | NC | unconnected | No connection; the datasheet pin drawing labels pin 3 as NC. |
| 4 | GND | power_in | Negative supply (ground). |
| 5 | SDA | bidirectional | Serial data input/output with an N-channel open-drain output and CMOS input; normally pulled up to VDD with a resistor and wire-ANDed with other open-drain devices. |
| 6 | SCL | input | Serial clock CMOS input; signals are processed on SCL rising/falling edges so rise/fall times must meet the datasheet, and the MCU port should be a CMOS output rather than open-drain. |
| 7 | INT | output | N-channel open-drain alarm/interrupt output whose mode is set by the control registers and which can be disabled by rewriting them. |
| 8 | VDD | power_in | Positive power supply, 1.8V to 5.5V. |
