PAD DESCRIPTIONS

8.1

SDA Serial Address/Data Input/Output

This is a bi-directional pad used to transfer addresses

and data into and data out of the device. It is an open

drain terminal, therefore the SDA bus requires a pull-up

Ω for 100 kHz, 1KΩ for 400

kHz).

For normal data transfer SDA is allowed to change only

during SCL low. Changes during SCL high are reserved

for indicating the START and STOP conditions.

8.2

SCL Serial Clock

This input is used to synchronize the data transfer from

and to the device.

8.3

DC Don’t Connect

This pad is used for test purposes and should not be

resistor.
