SC09A from ICMAN Tech, in a SOP-16. 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 | GND | power_in | Ground / negative supply reference for the device. |
| 2 | CMOD | passive | Charge-collection capacitor input. Connect a fixed capacitor (1nF~10nF, 4.7nF recommended) to GND; value does not affect sensitivity. |
| 3 | CDC | passive | Sensitivity-setting capacitor input. Connect a capacitor between 15pF and 100pF to GND; smaller value → higher sensitivity. |
| 4 | CIN0 | bidirectional | Capacitive touch sense input for touch pad 0. Connect to sense pad; leave floating if unused. |
| 5 | CIN1 | bidirectional | Capacitive touch sense input for touch pad 1. Connect to sense pad; leave floating if unused. |
| 6 | CIN2 | bidirectional | Capacitive touch sense input for touch pad 2. Connect to sense pad; leave floating if unused. |
| 7 | CIN3 | bidirectional | Capacitive touch sense input for touch pad 3. Connect to sense pad; leave floating if unused. |
| 8 | CIN4 | bidirectional | Capacitive touch sense input for touch pad 4. Connect to sense pad; leave floating if unused. |
| 9 | CIN5 | bidirectional | Capacitive touch sense input for touch pad 5. Connect to sense pad; leave floating if unused. |
| 10 | CIN6 | bidirectional | Capacitive touch sense input for touch pad 6. Connect to sense pad; leave floating if unused. |
| 11 | CIN7 | bidirectional | Capacitive touch sense input for touch pad 7. Connect to sense pad; leave floating if unused. |
| 12 | CIN8 | bidirectional | Capacitive touch sense input for touch pad 8. Connect to sense pad; leave floating if unused. |
| 13 | INT | output | Key-active interrupt output. Open-drain NMOS: pulled low when any key is touched, high-Z when no key is touched. Requires an external pull-up (typ. 10kΩ) if used; leave floating if unused. |
| 14 | SCL | input | I2C serial clock input (CMOS input, driven by host controller). Max bus rate 400 kbit/s with 10kΩ pull-up. Tie to GND or VDD if the I2C interface is unused. |
| 15 | SDA | bidirectional | I2C serial data input/output. Has an internal weak pull-up; an external 10kΩ pull-up is still recommended for bus operation. Tie to GND/VDD or leave floating if unused. |
| 16 | VDD | power_in | Positive power supply input, 2.5V to 6.0V (abs max 6.0V, electrical spec table lists max 6.5V). Typical Idd = 1.74mA @5V, 0.84mA @3V in normal mode; decouple with 100nF to GND. |
