Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | C1 | passive | Internal reference capacitor interface. Connect a 4.7 nF NPO capacitor (range 1 nF-10 nF) between this pin and ground; place capacitor as close to the IC as possible. |+| 2 | KEY1 | input | Capacitive touch key 1 input. Highest priority key. Optionally add a 0-10 pF NPO capacitor to ground for sensitivity trim (open = highest sensitivity). |+| 3 | KEY2 | input | Capacitive touch key 2 input. Second priority. Optionally add a 0-10 pF NPO capacitor to ground for sensitivity trim. |+| 4 | KEY3 | input | Capacitive touch key 3 input. Lowest priority. Optionally add a 0-10 pF NPO capacitor to ground for sensitivity trim. |+| 5 | OUT2 | output | Encoded data output bit 2 (MSB of 2-bit key code). Combined with OUT1: 00=KEY1, 01=KEY2, 10=KEY3, 11=no key pressed. High/low logic level output. |+| 6 | OUT1 | output | Encoded data output bit 1 (LSB of 2-bit key code). Combined with OUT2 to encode which key is pressed. High/low logic level output. |+| 7 | VDD | power_in | Positive supply, 2.5 V to 5.5 V. Recommend a 100 nF decoupling cap to GND and an optional 20 Ω series resistor from the board VDD rail to suppress noise. Typical Ivdd = 394 uA @ 3.0 V, 666 uA @ 5.0 V. |+| 8 | GND | power_in | Power ground / reference. Common return for supply, output logic, and touch reference. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Sam wing |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `AI32C`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Sam wing datasheet](docs/ai32c-datasheet.pdf) (7 pp, sha256 `59ec1134044746a1`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
