These are amongst others: 
 

 

GPMC (General-Purpose Memory Controller) 

 

PRU-MII1, PRU-MII2 (only available with AM3356, -7, -8, -9) 

 

PWMSS (Pulse-Width Modulation Subsystem) 

 

Enhanced Serial Audio Interface 

 

Ethernet 10/100 RMII 

 

More audio interfaces 

 

More I

2

C interfaces 

 

More SPI interfaces 

 

More UARTs 

 
 
All useful AM335x signals are routed to the TQMa335xL pads. 
There are no restrictions for customers using the TQMa335xL with respect to an integrated customised design. 
Please take note of that not all listed interfaces can be used simultaneously.
