CAP1106-1-AIA-TR from Microchip Tech, in a DFN-10-EP(3x3). 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 | CS1 | bidirectional | Capacitive touch sensor input 1 (analog I/O); connect to ground when unused. |
| 2 | ALERT# | output | Active-low alert/interrupt output for SMBus alert, open drain and 5V tolerant; connect to ground when unused. |
| 3 | SMDATA | bidirectional | Bi-directional open-drain SMBus data line, 5V tolerant; requires a pull-up resistor. |
| 4 | SMCLK | input | SMBus clock input, 5V tolerant; requires a pull-up resistor. |
| 5 | VDD | power_in | Positive power supply; VDD is 3.0 V to 3.6 V (typical 3.3 V) per Table 3-2. |
| 6 | CS6 | bidirectional | Capacitive touch sensor input 6 (analog I/O); connect to ground when unused. |
| 7 | CS5 | bidirectional | Capacitive touch sensor input 5 (analog I/O); connect to ground when unused. |
| 8 | CS4 | bidirectional | Capacitive touch sensor input 4 (analog I/O); connect to ground when unused. |
| 9 | CS3 | bidirectional | Capacitive touch sensor input 3 (analog I/O); connect to ground when unused. |
| 10 | CS2 | bidirectional | Capacitive touch sensor input 2 (analog I/O); connect to ground when unused. |
| 11 | GND | power_in | Exposed pad (from the footprint; not named in the datasheet pin table). |
