The chip is custom, and is designed by Commodore, and fabricated
by MOS Technology (Commodore Semiconductor?).  I dont beleive they
are second sourced, or are distributed for public consumption.  Data
sheets (rudimentry) can be found in the Amiga hardware manual's appendix.
You can also find info in various books on the C-64 for the chip
6522 (Can't remember number offhand), which is only slightly modified
to make the 8520.

The only place I know where you can buy these chips are as replacement parts
from a Commodore dealer.
