FPGA development board designed for XILINX Spartan-3E series, features the XC3S500E onboard, and integrates various standard interfaces, pretty easy for peripheral expansions.

XC3S500E development boardOverview


Open3S500E is an FPGA development board that consists of the mother board DVK600 and the FPGA core board Core3S500E.

Open3S500E supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with XILINX Spartan-3E series FPGA devices.

What's on the mother board

FPGA CPLD development board on board resource
  1. FPGA CPLD core board connector: for easily connecting core boards which integrate an FPGA CPLD chip onboard
  2. 8I/Os_1 interface, for connecting accessory boards/modules
  3. 8I/Os_2 interface, for connecting accessory boards/modules
  4. 16I/Os_1 interface, for connecting accessory boards/modules
  5. 16I/Os_2 interface, for connecting accessory boards/modules
  6. 32I/Os_1 interface, for connecting accessory boards/modules
  7. 32I/Os_2 interface, for connecting accessory boards/modules
  8. 32I/Os_3 interface, for connecting accessory boards/modules

All the I/O interfaces above:

  • capable of being simulated as USART, I2C, SPI, PS/2, etc.
  • capable of driving devices such as FRAM, FLASH, USB, Ethernet, etc.
  1. SDRAM interface
    • for connecting SDRAM accessory board
    • also works as FPGA CPLD pins expansion connectors
  2. LCD interface, for connecting LCD22, LCD12864, LCD1602
  3. ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
  4. 5V DC jack
  5. Joystick: five positions
  6. Buzzer
  7. Potentiometer: for LCD22 backlight adjustment, or LCD12864, LCD1602 contrast adjustment
  8. Power switch
  9. Buzzer jumper
  10. ONE-WIRE jumper
  11. Joystick jumper

For jumpers 17-19:

  • short the jumper to connect to I/Os used in example code
  • open the jumper to connect to other custom pins via jumper wires

The DVK600 supports a wide range of different core boards, therefore, some of the interfaces may be Not-Connected and useless while connecting to certain core board. For instance, while connecting to Core3S500E/CoreEP2C8, the '? 32I/Os_3' is Not-Connected.

What's on the Core3S500E

XC3S500E core board on board resource

    • Operating Frequency: 50MHz
    • Operating Voltage: 1.15V~3.3V
    • Package: QFP208
    • I/Os: 116
    • LEs: 500K
    • RAM: 360kb
    • DCMs: 4
    • Debugging/Programming: supports JTAG
  2. AMS1117-3.3, 3.3V voltage regulator
  3. AMS1117-2.5, 2.5V voltage regulator
  4. AMS1117-1.2, 1.2V voltage regulator
  5. XCF04S, onboard serial FLASH memory, for storing code
  6. Power indicator
  7. LEDs
  8. FPGA initialization indicator
  9. Reset button
  10. nCONFIG button: for re-configuring the FPGA chip, the equivalent of power reseting
  11. 50M active crystal oscillator
  12. JTAG interface: for debugging/programming
  13. FPGA pins expander, VCC, GND and all the I/O ports are accessible on expansion connectors for further expansion

Note: The Open3S500E does NOT integrate any programming/debugging function, a programmer/debugger is required.
