Atmel Corporation 

The touch performance of the SAM L21 PTC is identical to that of 

the SAM D series, but 

A touch accelerator was added to reduce CPU load and reduce overall 

power consumption 

Overall power consumption of the module was reduced 
 

The PTC is located in the low power domain and can remain 

powered while the rest of the system is sleeping 
 

 
 

Wake up from touch on less than 2uA! 

 

Updated Peripherals 

Peripheral Touch Controller (PTC)
