There are multiple ordering codes, depending on the included powersupply.• Spartan-3E Starter Kit Board (HS-SPAR3E-SK_xx)www.xilinx.com/s3estarterFor MicroBlaze™ processor development, consider the Spartan-3A DSP EmbeddedDevelopment board.• Spartan-3A DSP S3D1800A MicroBlaze Processor Edition (DO-SD1800A-EDK-DK-UNI-G)www.xilinx.com/products/devkits/DO-SD1800A-EDK-DK-UNI-G.htmFor PCI Express® applications, consider the Spartan-3 PCI Express Starter Kit.• Spartan-3 PCI Express Starter Kit (HW-S3PCIE-DK)www.xilinx.com/s3pcieFor simple Spartan-3 FPGA applications, consider the fairly basic Spartan-3 Starter Kitboard.• Spartan-3 Starter Kit (DO-SPAR3-DK)www.xilinx.com/s3starterAlso consider the capable boards offered by Xilinx partners:• Spartan-3 Generation Board Interactive Searchwww.xilinx.com/products/devboards/index.htmSpartan-3A and Spartan-3AN FPGAsThe Spartan-3AN FPGA platform offers nonvolatile pin-compatible versions of theSpartan-3A FPGA platform. The Spartan-3AN FPGAs support the same externalprogramming sources as Spartan-3A FPGAs, but add an additional internal SPI Flashprogramming mode. The internal SPI Flash can also be used for user data. TheSpartan-3A/3AN Starter Kit Board supports both external and Spartan-3AN internalconfiguration options.Spartan-3AN FPGAs require VCCAUX to be 3.3V while Spartan-3A FPGAs allow VCCAUXto be either 2.5V or 3.3V. The Spartan-3A/3AN Starter Kit Board uses a default VCCAUX of3.3V.Spartan-3A and Spartan-3AN FPGAs have different documentation and availability.
