SC04B from icman(晶尊微), 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 supply ground pin for the device (电源地), with the VDD and GND pins forming the power inputs. |
| 2 | CMOD | bidirectional | Charge-collection capacitor connection that takes a fixed-value capacitor, typically 4.7 nF within a 1 nF to 10 nF range, independent of sensitivity. |
| 3 | CDC | bidirectional | Sensitivity capacitor connection with a 5 pF to 100 pF range, where a smaller capacitance gives higher sensitivity. |
| 4 | CIN0 | bidirectional | Sense-pad input for touch key 0 that detects the capacitance change, left floating when unused. |
| 5 | CIN1 | bidirectional | Sense-pad input for touch key 1 that detects the capacitance change, left floating when unused. |
| 6 | CIN2 | bidirectional | Sense-pad input for touch key 2 that detects the capacitance change, left floating when unused. |
| 7 | CIN3 | bidirectional | Sense-pad input for touch key 3 that detects the capacitance change, left floating when unused. |
| 8 | NC | unconnected | Listed as NC in the pin table with no function or connection specified in the datasheet. |
| 9 | NC | unconnected | Listed as NC in the pin table with no function or connection specified in the datasheet. |
| 10 | OUT3 | output | Open-drain NMOS output for touch key 3 with an internal 10 kΩ pull-up, where the valid active level is strong low and the pin is left floating when unused. |
| 11 | OUT2 | output | Open-drain NMOS output for touch key 2 with an internal 10 kΩ pull-up, where the valid active level is strong low and the pin is left floating when unused. |
| 12 | OUT1 | output | Open-drain NMOS output for touch key 1 with an internal 10 kΩ pull-up, where the valid active level is strong low and the pin is left floating when unused. |
| 13 | OUT0 | output | Open-drain NMOS output for touch key 0 with an internal 10 kΩ pull-up, where the valid active level is strong low and the pin is left floating when unused. |
| 14 | SLPEN | input | Sleep-mode enable input, where tying it to GND disables sleep and tying it to VDD allows the chip to enter sleep mode after no touch for more than 70 s. |
| 15 | MD | input | Output mode select input, where tying it to GND gives direct output (low while touched) and tying it to VDD gives latched output that toggles on each touch. |
| 16 | VDD | power_in | Positive supply input with an operating range of 2.6 V to 6.0 V and a maximum rating of 6.0 V. |
