Pin Descriptions

The SCL input is used to clock all data into and out of the device.

The SDA is a bidirectional pin used to transfer data into and out of the device.

It is an open drain output and may be wire-ORed with any number of open drain or open collector

outputs.

The S0, S1 and S2 are device address inputs that are used to set three bits of the slave address. A

total of eight devices can be connected to the same bus.

WC (Write Control)

If the WC is High level, WRITE operations will not be executed. If the WC is Low level, the AK6003A

will be enabled to perform WRITE operation.

As the WC is internally pulled down to GND, the AK6003A will be enabled to perform WRITE

operation if the WC is left floating.

WC must not change from the start condition input to the stop condition input.
