OpenEP2C8-C Standard, ALTERA Development Board

5,200.00

OpenEP2C8-C is an FPGA development board that consists of the mother board DVK600 and the FPGA core board CoreEP2C8.

OpenEP2C8-C 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 ALTERA Cyclone II series FPGA devices. OpenEP2C8-C enables you to start your design with the Nios II processor easily and quickly.

Product Description

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 ‘⑧ 32I/Os_3’ is Not-Connected.

  2. AMS1117-3.3, 3.3V voltage regulator
  3. AMS1117-1.2, 1.2V voltage regulator
  4. EPCS16, onboard serial FLASH memory, for storing code
  5. Power indicator
  6. LEDs
  7. Reset button
  8. nCONFIG button: for re-configuring the FPGA chip, the equivalent of power reseting
  9. 50M active crystal oscillator
