Temperature sensor 

 

Illustration 5: 

Block diagram temperature sensor 

 
As with the TQMa53 a temperature sensor is also provided on the STK-MBa53. The same sensor as on the TQMa53 is used.  
It is connected to the same I2C bus (I2C2).  
The sensor on the STK-MBa53 has a different I2C address, (see Table 9 section 4.1.2, I2C address mapping).

The characteristic curve of the sensor is shown in the following illustration. The decimal values are the two's complement of 
register value "Temp". More details are to be taken from the data sheet.
