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 CIN2 CDC Capacitive Input Channel 2. The measured capacitance (sensor) is connected between the EXC2 pin and the CIN2 pin. If not used, this pin can be left open circuit or connected to GND. 4 CIN1 CDC Capacitive Input Channel 1. The measured capacitance (sensor) is connected between the EXC1 pin and the CIN1 pin. If not used, this pin can be left open circuit or connected to GND. 5 EXC2 CDC Excitation Output Channel 2. The measured capacitance is connected between the EXC2 pin and the CIN2 pin. If not used, this pin should be left as an open circuit. 6 EXC1 CDC Excitation Output Channel 1. The measured capacitance is connected between the EXC1 pin and the CIN1 pin. If not used, this pin should be left as an open circuit. 7 OUT1 Logic Output Channel 1. A high level on this output indicates proximity detected on CIN1. 8 OUT2 Logic Output Channel 2. A high level on this output indicates proximity detected on CIN2. 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. |
