TQMa335xL interface 

3.3.1

 

Pin assignment 

The multiple pin configurations of all AM335x-internal function units must be taken note of. 
The pin assignment shown in Table 38 refers to the corresponding 

BSP provided by TQ-Systems GmbH

The electrical and pin characteristics are to be taken from the AM335x (1), (3) and PMIC Data Sheet (6). 
 

3.3.2

 

Pinout TQMa335xL 

The TQMa335xL has a total of 209 pads. The following table shows the pad-out as top view through the TQMa335xL.  

(NC: the pad does not exist.)
