Description

CSN_IRQN

Digital

Input/Output

Chip select input for the SPI interface; external pull-up resistor required.

Push/pull interrupt output for I2C or SPI interface.

Programmable options, see Table 3.

RX1

Analog Input

Connect the receiver coil 1 (sine) between the RX2 and RX1 pins.

RX2

RX3

Analog Input

Connect the receiver coil 2 (cosine) between the RX4 and RX3 pins.

RX4

TX1

Analog

Input/Output

Connect the transmitter coil between the TX1 and TX2 pins. The resonant frequency

is adjusted with a parallel capacitor CT between TX1 and TX2 or with capacitors CT1

from TX2 to GND and CT2 from TX1 to GND.

TX2

VDDA

Supply

Internal analog voltage supply. Connect a capacitor CVA to the GND pin.

GND

Supply

Common ground connection.

VDD

Supply

External supply voltage. Connect two parallel capacitors CVD to the GND pin.

SCK_SCL

Digital Input

Clock input for digital programming and diagnostic interfaces:

 I2C interface: SCL clock input; external pull-up resistor mandatory,

see Figure 18, Figure 19, and Figure 20.

 SPI interface: SCK clock input; external pull-up resistor is optional,

see Figure 16 and Figure 17.
