Now with up to 42% less power consumption and a 12% increase in performance enabled by ISE® Design Suite， they provide up to 150K logic cells， integrated PCI Express® blocks， advanced memory support， 250MHz DSP slices， and 3.2Gbps low-power transceivers.
Spartan 6 LX150T Development Board
The Spartan-6 family provides leading system integration capabilities with the lowest total cost for high-volume applications. The thirteen-member family delivers expanded densities ranging from 3，840 to 147，443 logic cells， with half the power consumption of previous Spartan families， and faster， more comprehensive connectivity. Built on a mature 45 nm low-power copper process technology that delivers the optimal balance of cost， power， and performance， the Spartan-6 family offers a new， more efficient， dual-register 6-input lookup table （LUT） logic and a rich selection of built-in system-level blocks. These include 18 Kb （2 x 9 Kb） block RAMs， second generation DSP48A1 slices， SDRAM memory controllers， enhanced mixed-mode clock management blocks， SelectIO？technology， poweroptimized high-speed serial transceiver blocks， PCI Express？compatible Endpoint blocks， advanced system-level power management modes， auto-detect configuration options， and enhanced IP security with AES and Device DNA protection. These features provide a lowcost programmable alternative to custom ASIC products with unprecedented ease of use. Spartan-6 FPGAs offer the best solution for high-volume logic designs， consumer-oriented DSP designs， and cost-sensitive embedded applications. Spartan-6 FPGAs are the programmable silicon foundation for Targeted Design Platforms that deliver integrated software and hardware components that enable designers to focus on innovation as soon as their development cycle begins.
