Product Description
Features
Description
• 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 versati...
