thermal pad XS1-L1 64 pins

Postby In_Control001 » Thu May 13, 2010 10:15 am

Hi guys,

SomeOne Knows how many Watts an XS1-L1 64 pins disipates.

I need this to design my board. I want to use 2 XS1-L1's on both side of my board.



Kind regards,
Jo

Probably not the most confused programmer anymore on the XCORE forum.

The big pad in centre of the chip (as opposed to the pins around the edge of the chip) MUST be connected to ground. It is the only digital ground connection (check the datasheet for 'PADDLE').

In addition to making the ground connection it does offer a low thermal resistance path to a ground plane. The L1 runs pretty cool though.

Does this answer your question?
