7.1 Connecting the AS5130

The AS5130 can be connected to an external controller in several ways as listed below:

Serial 3-wire connection (default setting)

Serial 3-wire connection (OTP programming option)

1-wire PWM connection

Analog output

Analog Sin/Cos outputs with external interpolator

7.1.1 Serial 3-Wire Connection (Default Setting)

In this mode, the AS5130 is connected to the external controller via three SSI signals: Chip Select (CS), Clock (CLK) input and DIO (Data) in/

output. This configuration not only helps to read and write data but also defines different operation modes. The data transfer in all cases is done

via the DIO port.
