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.
