The USB Blaster 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 Blaster cable to interactively download configuration data to a system during prototyping or to program data into the system during production. It surpports the ALTERA total series FPGA/CPLD devices, Active Serial Configuration Devices, Enhanced Configuration Devices, and supports AS, PS, JTAG three download modes.
