Looks like an amazing alternative to LP when you need USB or more pins, flash, ram. Nice work!


Just noticed you criss-cross the USB D+/D- lines with a via. It has been discussed elsewhere in this forum that it's better not to (although I don't know if it's a real problem or just exaggeration). One solution is to enter through the corner and connect to the pads from the "inside" of the chip.


EDIT: Maybe a CCW 45

The design guide tells you to limit the number of vias, but they are OK.

Route the high-speed USB signals using a minimum of vias and corners. This reduces signal reflections and impedance changes.

I did consider doing something like below, but I am not sure if this will be any better.

Placing 5510 or USB on the bottom layer would probably be the best solution here.

Are there any software USB diagnostic tools I could use that will show mi transfer errors?






Also, relative to some other designs out there, I don't think my design is that problematic.
