The Xilinx Parallel Cable IV (PC4) (Figure is a high-speed download cable that configures or programs all Xilinx FPGA, CPLD, and ISP PROM devices. The cable takes advantage of the IEEE 1284 ECP protocol and Xilinx iMPACT software to increase download speeds over eight times faster than existing solutions. The cable automatically senses and adapts to target I/O voltages and is able to accommodate a wide range of I/O standards from PC4 is designed for use in a desktop environment. Note: Xilinx also offers the Platform Cable USB II with a USB 2.0

interface to the host PC and similar capabilities as the Parallel Cable IV. See DS593, Platform Cable USB II, for details.

The cable is externally powered from either a power brick or by interfacing to a standard PC mouse or keyboard connection. A bi-color status LED indicates the presence of operating and target reference voltages.

PC4 supports the widely used industry-standard IEEE 1149.1 boundary-scan (JTAG) specification, the Xilinx slave-serial mode for Xilinx FPGA devices, and serial peripheral interface for serial-access flash PROM programming. PC4 supports indirect programming of select flash memories including the Platform Flash XL configuration and storage device (via an FPGA JTAG port). The cable interfaces to target systems using a ribbon cable that features integral alternating ground leads to reduce crosstalk and improve signal integrity.

Xilinx Parallel Cable IV error-free connection. A very small footprint, keyed mating connector is all that is required on the target system. Refer to Figure 4 for the appropriate connector pin assignments and sample vendor part numbers. Figure 5 shows the POD and its dimensions. The Parallel Cable IV can also interface to target systems using flying lead wires. However, these are not included with PC4. The flying lead wires and additional ribbon cables can be purchased separately from the Xilinx Online Store.

The PC4 connects to any PC using Microsoft® Windows® 2000, Windows XP, or Linux(1) operating systems through the built-in, standard IEEE 1284 DB25 parallel (printer) port connector.(2) To fully utilize the higher speeds of this cable, the host PC must have a parallel port that is enabled to support extended capability port (ECP) mode.(3) If ECP mode is not enabled, the PC4 defaults to compatibility mode and does not run at the optimum speeds listed.

1. 2. See the System Requirements section in the ISE software manual for more specific operating system requirements. Xilinx makes no representations about compatibility with thirdparty IEEE 1284 add-on adapters and does not support the addon adapters. Refer to host PC BIOS to see if ECP mode is enabled.

An insulation displacement connector (IDC) ribbon cable is supplied and recommended for connection to target systems. See Figure 2 and Figure 3. This cable incorporates multiple signal-ground pairs and facilitates
