برد FPGA اسپارتان spartan-3e

· Main chip XILINX company General FPGA : Spartan-3E series XC3S500PQE208

· Onboard 64Mbit SDRM HY57V641620

· Onboard M25P16 serial configuration chip, supports JTAG / SPI Flash Mode

· Onboard 50MHz active crystal, a system master clock work

· Using high-power LDO power management chip LM1085-3.3V , maximum support3A of 3.3V voltage output

· Use 1117-1.2V regulator chip, providing FPGA core voltage

· Use 1117-2.5V regulator chip, providing FPGA core voltage

· Careful decoupling design, using a large number of decoupling capacitors

· It provides dual 5V DC power socket, core board to facilitate use alone and in combination

· Red Power LED and IN5819 high-speed Schottky diode to prevent reverse power

· 1 System Reset button Reset , also can be used as user input keys

· 1 a FPGA reconfiguration key

· 2 two LED lights, water lights do experiments

· Self-locking button power switch

· 1 System Reset RESET , can be used as user input keys

· Reconfiguration button and configure success indicator is very intuitive for download

· Well-designed distribution of IO resources, in addition to SDRAM all outside IOleads , three expansion interface socket, general purpose 2.54mm pitch

· JTAG interface corresponds to the downloaded file is .bit , logic downloaded to theFPGA , the speed is fast, but lost power after the next, learning usually recommend using this interface

· M25P16 logic through JTAG interfaces indirect download, slower, will not be lost after power off, in case you need the firmware
