Preliminary specification
320 macrocell SRAM CPLD
PZ3320C/PZ3320N
(LZIA). The LZIA is a virtual crosspoint switch that connects the
Logic Blocks to each other and to the GZIA. The feedback from all
80 macrocells, input from the I/O pins, and the 64 bit input bus from
the GZIA are input into the LZIA. The LZIA outputs 36 signals into
each Logic Block and 64 signals into the GZIA.
XPLA2 Fast Module
Each Fast Module consists of four Logic Blocks of 20 macrocells
each. Depending on the package, either 8 or 12 of the 20 macrocells
in each Logic Block are connected to I/O pins, and the remaining
macrocells are used as buried nodes. These four Logic Blocks are
connected together by the Local Zero Power Interconnect Array
