Parallel Cable IV Description
The Xilinx Parallel Cable IV (PC4) (Figure 1) 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 1.5V to
5V. 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 DS
593, Platform Cable USB II, for details.
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.
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.

Connecting to Host Computer

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