Xilinx Spartan6 LX150T开发方案

　　Avnet公司的Xilinx Spartan-6 LX150T开发套件是采用Xilinx公司的XC6SLX150T-3FGG676器件，它的串行吉比特收发器接口（GTP）能连接到片上PCI Express® x1硬宏元或PCI Express x4软宏元，一个SFP连接器和一个SATA主接口。系统板包括DDR3，SDRAM，闪存，10/100/1000以太网PHY和串行口，其它特性还包括USB端口。

　　Spartan®-6 LX FPGAs are opTImized for applicaTIons that require the absolute lowest cost. 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.

　　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.
