256-ball caBGA BGA Breakout Examples
This BGA breakout and routing example places a MachXO PLD in a 14x14 mm, 0.8 mm pitch, 256-ball caBGA
package (LCMXO2280-B256/BN256) into two fabrication scenarios. One for a 6-layer stack up with maximum I/O
utilization and a 4-layer with about 10% fewer I/Os. The 6-layer design (Example #1), demonstrates the best use of
mechanically drill blind vias to place caps near power pins to minimize layers.
