Spartan-3A/3AN FPGA Starter Kit Board User Guidewww.xilinx.com 19UG334 (v1.1) June 19, 2008Key Components and FeaturesRUsing one or two external multimeters, measure the corresponding difference in currentconsumption, as described in “Measuring Power Across Voltage Supply Jumpers,” page137.Caution! Do not set the SUSPEND switch to “SUSPEND” while programming the parallel NORFlash PROM using configuration bitstream #4, as described in Table 1-2.RS-232 Serial Port Control OptionOptionally, control the demonstration design using a serial port connection to a PC orworkstation. On a PC, use the HyperTerminal program to communicate to the FPGAapplication, as shown in Figure 1-6. Using a standard, straight-through 9-pin serial cable,connect the PC’s 9-pin RS-232 port to the board’s DCE connector (see Figure 7-1, page 63).When the demonstration design begins operating, it transmits a message using the serialport.Press a number key on the PC to load the associated MultiBoot bitstream listed in Table 1-2.Key Components and FeaturesThe key features of the Spartan-3A FPGA Starter Kit board or the Spartan-3AN FPGAStarter Kit board are:• Spartan-3A FPGA Starter Kit Board: Xilinx 700K-gate XC3S700A Spartan-3A FPGAin the Pb-free 484-ball BGA package (FGG484)• Spartan-3AN FPGA Starter Kit Board: Xilinx 700K-gate XC3S700AN Spartan-3ANnonvolatile FPGA in the Pb-free 484-ball BGA package (FGG484)♦ Internal 8 Mbit In-System Flash memory♦ Store FPGA configuration bitstream or nonvolatile data• 4 Mbit Xilinx Platform Flash configuration PROM• 64 MByte (512 Mbit) of DDR2 SDRAM, 32Mx16 data interface• 4 MByte (32 Mbit) of parallel NOR FlashFigure 1-6: Use HyperTerminal and a Standard Serial Cable to Connect to BoardUG334_c1_06_052707
