Third Generation Field-Programmable Gate Arrays
– Abundant flip-flops
– Flexible function generators
– On-chip ultra-fast RAM
The XC4000 families of Field-Programmable Gate Arrays (FPGAs) provide the benefits of custom
CMOS VLSI, while avoiding the initial cost, time delay, and inherent risk of a conventional masked gate array.
– Dedicated high-speed carry-propagation circuit – Wide edge decoders
The XC4000 families provide a regular, flexible, programmable architecture of Configurable Logic Blocks (CLBs),
– Hierarchy of interconnect lines
interconnected by a powerful hierarchy of versatile routing
– Internal 3-state bus capability
resources, and surrounded by a perimeter of program-

Flexible Array Architecture
XC4000-family devices have generous routing resources to accommodate the most complex interconnect patterns.
– Programmable logic blocks and I/O blocks
XC4000A devices have reduced sets of routing resources,
– Programmable interconnects and wide decoders
sufficient for their smaller size. XC4000H high I/O devices

CMOS Process
– High-speed logic and Interconnect
maintain the same routing resources and CLB structure as the XC4000 family, while nearly doubling the available I/O.
– Low power consumption
The devices are customized by loading configu...
