Waveshare USB Blaster V2, ALTERA Programmers & Debuggers 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 iteratively 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. USB Blaster Download Cable is designed for ALTERA FPGA, CPLD, Active Serial Configuration Devices and Enhanced Configuration Devices, USB 2.0 connection to the PC and JTAG, AS, PS to the target device.
