100-ball csBGA BGA Breakout and Routing Examples
These examples place a MachXO PLD in a 8x8 mm, 0.5 mm pitch, 100-ball csBGA package (LXMXO640-
M100/MN100) into two fabrication scenarios. One for a 6-layer stack up with maximum I/O utilization and a 4-layer
with about 15% fewer I/Os. The 4-layer (Example #2) design makes maximum use of via and trace geometry to
reduce layer count and ease fabrication while still maintaining high I/O usage.
