Table 4-1 Pin Functions
PIN TYPE(1) DESCRIPTION
NO. NAME
1 SCL I I2C clock input
2 SDA I/O 12C data input/output
3 CLKIN I Controller Clock input. Tie this pin to GND if internal oscillator is selected
4 ADDR I I2C Address selection pin: when ADDR=L, I2C address = 0x2A, when ADDR=H, I2C address = 0x2B.
5 INTB O Configurable Interrupt output pin
6 SD I Shutdown input
7 VDD P Power Supply
8 GND G Ground
9 IN0A A Capacitive sensor input 0
10 IN0B A Capacitive sensor input 0
11 IN1A A Capacitive sensor input 1
12 IN1B A Capacitive sensor input 1
13 IN2A A Capacitive sensor input 2 (FDC2114 / FDC2214 only)
14 IN2B A Capacitive sensor input 2 (FDC2114 / FDC2214 only)
15 IN3A A Capacitive sensor input 3 (FDC2114 / FDC2214 only)
16 IN3B A Capacitive sensor input 3 (FDC2114 / FDC2214 only)
DAP DAP(2) N/A Connect to ground
(1) I = Input, O = Output, P=Power, G=Ground, A=Analog
(2) There is an internal electrical connection between the exposed Die Attach Pad (DAP) and the GND pin of the device. Although the DAP can be left floating, connect the DAP to the same potential as the GND pin of the device for best performance. Do not use the DAP as the primary ground for the device. The device GND pin must always be connected to ground.
