XILINX FPGA Development Board Xilinx Spartan -3E XC3S250E with DVK600+ Core3S250E+10 Accessory Kits = Open3S250E Package A

Overview

Open3S250E is an FPGA development board that consists of the mother board DVK601 and the FPGA core board Core3S250E.

Open3S250E 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

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. 8I/Os_3 interface, for connecting accessory boards/modules
5. 8I/Os_4 interface, for connecting accessory boards/modules
6. 16I/Os_1 interface, for connecting accessory boards/modules
7. 16I/Os_2 interface, for connecting accessory boards/modules
8. 32I/Os_1 interface, for connecting accessory boards/modules
9. 32I/Os_2 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. FPGA expansion connectors
   • FPGA pins are accessible on expansion connectors
   • for connecting SDRAM accessory board
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. Buzzer
5. Joystick: five positions
6. Potentiometer: for LCD22 backlight adjustment, or LCD12864, LCD1602 contrast adjustment
7. Buzzer jumper
8. Joystick jumper
9. ONE-WIRE jumper

For jumpers 16-18:

• 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 DVK601 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 Core3S250E, the '8I/Os_3' and '8I/Os_4' are Not-Connected.

What's on the Core3S250E

1. XC3S250E: the XILINX Spartan-3E FPGA device which features:
   • Operating Frequency: 50MHz
   • Operating Voltage: 1.15V~3.3V
   • Package: QFP144
   • I/Os: 80
   • LEs: 250K
   • RAM: 216kb
   • 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. XCF02S, 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. Power switch
12. 50M active crystal oscillator
13. 5V DC jack
14. JTAG interface: for debugging/programming
15. FPGA pins expander, VCC, GND and all the I/O ports are accessible on expansion connectors for further expansion
16. LED jumpers
