144-ball csBGA BGA Breakout Examples
These examples place an ispMACH 4000ZE in a 7x7 mm, 0.5 mm pitch, 144-ball csBGA package (LC4256ZE-
MN144) into two fabrication scenarios. One for a 6-layer stack up with maximum I/O utilization and a 4-layer with
about 5% fewer I/Os. The 6-layer (Example #1) design avoids uses of micro vias and takes advantage of removed
pads on inner layers to route all pins out to 6 layers with good layer structure for high-speed signal integrity.
