Mercury Code Cyclone V

Mercury Code Cyclone V Industrial Low Cost Development Board

The DB5CEA7 is the fourth generation of DBC industrial Development Boards. The latest version is based on the Altera Cyclone V Low cost FPGA 5CEFA7F27C7N. Two DDR3 memory banks are connected by a 16 bit width using the hard Memory Controller IP of the FPGA and a 8 bit width using a soft memory controller in the same I/O Bank.
Several Industrial peripherals are implemented like Dual Ethernet (10/100Mbit), Dual CAN Transceiver, quad RS485 and RS232. A LVDS Based TFT interface is implemented, 8 User LEDs, 4 Buttons and a Navigation key. For extension 32 GPIO Pins are available for 3.3 V and 16 GPIOs with selectable IO Voltage. Additional 16 Channels 24V I/O are provided for direct implementation into PLC Systems.
