... BGA package is being discontinued for the XC95216. Architecture Description Each XC9500 device is a subsystem consisting of multiple Function Blocks (FBs) and I/O Blocks (IOBs) fully intercon- nected by the Fast CONNECT™ switch matrix. The IOB provides buffering for device inputs and outputs. Each FB 2 XC9572 XC95108 XC95144 - - ...
