The Xilinx DLC7 Parallel Cable IV is a high-speed download cable that interfaces a PC’s parallel port to Xilinx FPGAs, CPLDs, and ISP PROMs for device programming and configuration. Operating over an IEEE 1284 ECP-compliant parallel port, it achieves download speeds up to 5 Mb/s and supports multiple programming modes including JTAG, Xilinx Slave-Serial, and SPI protocols. The cable automatically senses and adapts to target I/O voltages spanning 1.5V to 5V, with integrated protection circuits that 3-state output buffers when target reference voltage drops below 1.3V DC.
