(This question has come up a few times through other media, so I thought I would record it here)
The xn files for xCORE-200 boards (using the eXplorer as an example) have the following package identified:
<Package id="0" Type="XS2-UnA-512-FB236">
How does this relate to the xCORE-200 part numbers?

If we generalise the structure, the mapping is described by the following examples:
XS2-UnA-512-FB236 => XU2n-512-FB236
XS2-UFnA-512-FB236 => XUF2n-512-FB236
Where n is the two-digit number of cores.
If you like regular expressions, I think this describes the general case:
xn file syntax: XS2\-(\w+)nA-(\d{3})-(\w{5})
xCORE-200 target: X$1n-$2-$3
XS2-UnA-512-FB236 => XU2n-512-FB236
XS2-UFnA-512-FB236 => XUF2n-512-FB236
Where n is the two-digit number of cores.
