Pin Configuration Table 4. Pin Function Descriptions Pin No. Mnemonic Description 1 GND Ground Pin. 2 VDD Power Supply Voltage. This pin should be decoupled to GND using a low impedance capacitor, for example, 0.1 μF X7R multilayer ceramic. 3 NC This pin should be left as an open circuit or connected to GND. 4 CIN CDC Capacitive Input. The measured capacitance (sensor) is connected between the EXC pin and the CIN pin. 5 NC This pin should be left as an open circuit. 6 EXC CDC Excitation Output. The measured capacitance is connected between the EXC pin and the CIN pin. 7 OUT Logic Output. High level on this output indicates proximity detected on the capacitive input. 8 NC This pin should be left as an open circuit. 9 SCL Serial Interface Clock Input. Connects to the master clock line. Requires a pull-up resistor if not provided elsewhere in the system. 10 SDA Serial Interface Bidirectional Data. Connects to the master data line. Requires a pull-up resistor if not provided elsewhere in the system. |
