64-ball ucBGA BGA Breakout and Routing Example
This example places an ispMACH 4000ZE CPLD in a 4x4 mm, 0.4 mm pitch, 64-ball ucBGA package (LC4064ZE-
UMN64) in an n-layer stack up with maximum I/O utilization. This example demonstrates a modified dogbone
fanout technique to get access to all pins yet limiting number of layers and via schedules, while setting up layers to
use reference planes for high-speed signal traces.
