XW09B from Sam wing, in a SOP-16. 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 | GND | power_in | Power ground (电源地) for the device. |
| 2 | C1 | passive | Internal balance capacitor interface; the datasheet gives a 1 nF to 10 nF range and recommends 4.7 nF, with the capacitor placed close to the IC. |
| 3 | CSEL | passive | Sensitivity-setting capacitor interface; the stated range is 0 to 100 pF, and a smaller capacitance gives higher sensitivity. |
| 4 | PAD0 | input | Capacitive touch sense pad 0; leave the pin floating when unused, and it has the highest priority in AO mode. |
| 5 | PAD1 | input | Capacitive touch sense pad 1; leave the pin floating when unused. |
| 6 | PAD2 | input | Capacitive touch sense pad 2; leave the pin floating when unused. |
| 7 | PAD3 | input | Capacitive touch sense pad 3; leave the pin floating when unused. |
| 8 | PAD4 | input | Capacitive touch sense pad 4; leave the pin floating when unused. |
| 9 | PAD5 | input | Capacitive touch sense pad 5; leave the pin floating when unused. |
| 10 | PAD6 | input | Capacitive touch sense pad 6; leave the pin floating when unused. |
| 11 | PAD7 | input | Capacitive touch sense pad 7; leave the pin floating when unused. |
| 12 | PAD8 | input | Capacitive touch sense pad 8; leave the pin floating when unused, and it has the lowest priority in AO mode. |
| 13 | INT | output | Key-active output, open-drain (OD) type. |
| 14 | AO | output | Analog voltage output that equals VDD with no key pressed and 5/16 VDD (PAD0) to 13/16 VDD (PAD8) for a single pressed key. |
| 15 | BUZZ | output | Buzzer drive output with a 2.7 kHz square wave that can drive a buzzer directly, with a stated source current of 30 mA at VDD = 5.0 V. |
| 16 | VDD | power_in | Positive supply; operating range 2.5 V to 5.5 V, with an absolute maximum rating of -0.3 V to 6.0 V. |
