Intel/Altera Cyclone IV FPGA Development Board -- DueProLogic

  • Intel/Altera Cyclone IV FPGA includes 6,000 Logic Elements with two clock multipliers. The Cyclone IV FPGA is the perfect balance of inexpensive cost versus plentiful logic cells, 20KBytes of SRAM, and General Purpose Input/Output pins. This is a great board to learn how to program FPGA's..
  • Built in programmer cable allows configuring the FPGA with a single Micro-B cable. The DPL can be powered from the USB cable or from the Barrel Connector. A separate JTAG header can also be used to program the FPGA using a compatible USB Blaster cable..
  • 6x6 LED Array allows character and animations to be displayed at ultra fast speed. LED blocks can be individually turned on/off to allow LED signals to be used as I/O's.
  • 70 Inputs/Outputs originating at the FPGA are available at Stackable Headers organized around the edge of the board. The user can configure these I/O's using the FPGA project code..
  • The DPL contains two oscillators, 66MHz and 100MHz. The 66MHz oscillator is used to provide clocking for the EPT ActiveHost USB communications core. The 100MHz oscillator can be used by the user clocked up using one of the onboard Clock-DLL modules..
