Description: USB V2 Download Cable, compatible with FOR ALTERA USB FPGA/CPLD programmer. The USB Download Cable interfaces a USB port on a host computer to an Altera FPGA mounted on a printed circuit board. The cable sends configuration data from the PC to a standard 10-pin header connected to the FPGA. You can use the USB cable to iteratively download configuration data to a system during prototyping or to program data into the system during production. It surpports most of the for ALTERA FPGA/CPLD devices, Active Serial Configuration devices, Enhanced Configuration devices, and supports AS, PS, JTAG three download modes. Hardware Solution: High speed FT245+CPLD+244 solution, similar download speed as the for-original ALTERA USB , with the same operation.Download speed 1-3 times faster than other schemes, such as 68013 or C8051F. Supports most of the ALTERA FPGA/CPLD devices, Active Serial Configuration devices, and Enhanced Configuration Devices. Supports AS, PS, JTAG three download modes. High-speed, stable, and internal FT245R+CPLD designed. Supports 1.2-5V programming voltage. Supports Nios II of embedded processor communication and debugging. Supported Softwares: for Quartus II integrated development environment. for NIOS II IDE integrated development environment. for NIOS II integrated development environment. Supported Devices: Tested devices are listed below, including but not limited to: for CPLD: MAX3000, MAX7000A/B/S, MAX9000 and MAX II etc. for FPGA: Stratix, Stratix II, Cyclone, Cyclone II, CycloneIII, ACEX 1K, 20K and FLEX 10K etc. Active Serial Configuration Devices including: EPCS1, EPCS4, EPCS16 etc. Enhanced Configuration Devices including: EPC1, EPC4 etc. Connects to PC: Computer connection via USB 2.0 interface. Connects to target board: Target board connection via JTAG, AS, PS interfaces. The figure 1, 2,and 3 below shows the header pi
