Waveshare OpenEP4CE10-C Standard FPGA development board designed for ALTERA Cyclone IV series,

Overview

OpenEP4CE10-C is an FPGA development board that consists of the mother board DVK600 and the FPGA core board CoreEP4CE10.

OpenEP4CE10-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 IV series FPGA devices. OpenEP4CE10-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.
