OpenEP4CE6-C is an FPGA development board that consists of the mother board DVK601 and the FPGA core board CoreEP4CE6.
OpenEP4CE6-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. OpenEP4CE6-C enables you to start your design with the Nios II processor easily and quickly.
What's on the mother board
FPGA CPLD core board connector: for easily connecting core boards which integrate an FPGA CPLD chip onboard, such as Core3S250E
8I/Os_1 interface, for connecting accessory boards/modules
8I/Os_2 interface, for connecting accessory boards/modules
8I/Os_3 interface, for connecting accessory boards/modules
8I/Os_4 interface, for connecting accessory boards/modules
16I/Os_1 interface, for connecting accessory boards/modules
16I/Os_2 interface, for connecting accessory boards/modules
32I/Os_1 interface, for connecting accessory boards/modules
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.
FPGA expansion connectors
FPGA pins are accessible on expansion connectors
for connecting SDRAM accessory board
LCD interface, for connecting LCD22, LCD12864, LCD1602
ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
Joystick: five positions
Potentiometer: for LCD22 backlight adjustment, or LCD12864, LCD1602 contrast adjustment
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
