Waveshare 7686 OpenEP2C5-C Standard

OpenEP2C5-C is an FPGA development board that consists of the mother board DVK601 and the FPGA core board CoreEP2C5.

OpenEP2C5-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. OpenEP2C5-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. 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

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

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 CoreEP2C5

1. EP2C5T144C8N:the ALTERA Cyclone II FPGA device which features:
   • Operating Frequency:50MHz
   • Operating Voltage:1.15V~3.465V
   • Package:QFP144
   • I/Os:79
   • LEs:4.6K
   • RAM:120kb
   • PLLs:2
   • Debugging/Programming: supports JTAG
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. Power switch
10. 50M active crystal oscillator
11. 5V DC jack
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
14. LED jumpers, short the jumpers to drive the LEDs
