Overview

OpenEP3C16-C is an FPGA development board that consists of the mother board DVK600 and the FPGA core board CoreEP3C16.

OpenEP3C16-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 III series FPGA devices. OpenEP3C16-C enables you to start your design with the Nios II processor easily and quickly.

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. 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

9. SDRAM interface
   • for connecting SDRAM accessory board
   • also works as FPGA CPLD pins expansion connectors
10. LCD interface, for connecting LCD22, LCD12864, LCD1602
11. ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
12. 5V DC jack
13. Joystick: five positions
14. Buzzer
15. Potentiometer: for LCD22 backlight adjustment, or LCD12864, LCD1602 contrast adjustment
16. Power switch
17. Buzzer jumper
18. ONE-WIRE jumper
19. Joystick jumper

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.

What's on the CoreEP3C16

1. EP3C16Q240C8N:the ALTERA Cyclone III FPGA device which features:
   • Operating Frequency: 50MHz
   • Operating Voltage: 1.15V～3.465V
   • Package: QFP240
   • I/Os: 136
   • LEs: 15408
   • RAM: 504kb
   • PLLs: 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. EPCS16, onboard serial FLASH memory, for storing code
6. Power indicator
7. LEDs
8. Reset button
9. nCONFIG button: for re-configuring the FPGA chip, the equivalent of power reseting
10. 50M active crystal oscillator
11. JTAG interface: for debugging/programming
12. FPGA pins expander, VCC, GND and all the I/O ports are accessible on expansion connectors for further expansion

Note: The OpenEP3C16-C does NOT integrate any programming/debugging function, a programmer/debugger is required.
