Hey this is handy, strange I/O pinout choice but I guess that's for the USB folks..

Why using link C rather than Link A?

Nice to have a smaller package, any idea on pricing couldn't find them listed on distis yet

But cool, will have some fun with this

On the data sheet page 10 it refers to 'DEBUG_N' but this isn't actually present on the package?

I assume its just a typo/bad diagram rather than a pinout error?

Because the link C pins aren't available in ULPI mode.

The text refers to DEBUG_N as well. I suppose this is copy-pasta from the older
documents (it is identical text).

I presume you meant link A pins, but the link pins are available in ULPI mode, as links, just not as GPIO.

I would have preferred a 4 bit port to 4 pins of the 32 bit port, but then I'm not a big USB user.

I also notice the words 'MCU' and 'Microcontroller' are not used in the datasheet which is encouraging

There is another mention of DEBUG_N on page 8 which I also presume is a copy and paste mistake.

Is there anything we need to understand about this package's operation given the missing debug pin, i.e. does it have any knock on effects?

Also can the X0D52-55 pins be used in a select input without issues due to overlap on the 32bit port, especially if all the other GPIO pins are in use?

That one yes :-) P4B

Yeah that's right I think. The docs (XS1-L hardware design checklist) suggest
otherwise.

Hi Corin,
Please what will be the price for these devices? and when will they be available (not listed on Digikey yet)?

I think the price will be probably like the '64 part.
