Example 75°C:

75°�� / 0.0625°�� = 1200 = �� 0100 1011 0000 = �� 4��0

Example -40°C:

|−40°��| / 0.0625°�� + 1 = 640 + 1 = �� 0010 1000 0000 + 1 = 1101 0111 1111 + 1 =

1101 10000 0000 = �� 80

Serial Interface

The device employs a standard I²C-serial bus.

6.3.1

Bus Description

A data transfer must be invoked by a master device (e.g. microcontroller) which de-fines the access to

the slave device. The master device defines and generates the serial clock (SCL) and the start/stop

conditions.

In order to address a specific device, a START condition has to be generated by the master device by

pulling the data line (SDA) from a logic high level to a logic low lev-el while the serial clock signal

(SCL) is kept at high level.
