Virtex-5 LX

Virtex-5 FPGA



The Xilinx® Virtex-5 LX Platform consists of six devices offering up to 330,000 logic cells, 1200 user I/Os, 10-Mbits of 36-Kbit block RAM, and 3.2-Mbits of distributed RAM, plus an abundance of hardened intellectual property (IP) blocks.
Based on the revolutionary new 65-nm ExpressFabric™ technology, the new Virtex-5 LX devices allow designs to be packed more efficiently, thus improving performance and utilization while reducing power consumption. Virtex-5 LX FPGAs deliver 30 percent higher performance, consume 45 percent less area and provide the industry’s lowest dynamic power – 35 percent lower than previous generation 90-nm FPGAs. The Virtex-5 LX family also features 550 MHz clocking technology with performance-tuned IP blocks. High-performance SelectIO™ features provide the fastest connection possible to external memory such as 667 Mbps DDR2 SDRAM and 1200 Mbps QDR II SRAM.
