If design revisioning or other advanced feature support is
required, the XCFxxP can be used as an alternative to the
XCF01S, XCF02S, or XCF04S.
Assumes compression used.
The largest possible Virtex-II bitstream sizes are specified. Refer
to the Virtex-II User Guide for information on bitgen options
which affect bitstream size.
Programming
In-System Programming
In-System Programmable PROMs can be programmed
individually, or two or more can be daisy-chained together
and programmed in-system via the standard 4-pin JTAG
protocol as shown in
In-system programming
offers quick and efficient design iterations and eliminates
unnecessary package handling or socketing of devices. The
programming data sequence is delivered to the device
using either Xilinx iMPACT software and a Xilinx download
cable, a third-party JTAG development system, a
JTAG-compatible board tester, or a simple microprocessor
interface that emulates the JTAG instruction sequence. The
iMPACT software also outputs serial vector format (SVF)
files for use with any tools that accept SVF format, including
automatic test equipment. During in-system programming,
the CEO output is driven High. All other outputs are held in
a high-impedance state or held at clamp levels during
in-system programming. In-system programming is fully
supported across the recommended operating voltage and
temperature ranges.

OE/RESET
The 1/2/4 Mbit XCFxxS Platform Flash PROMs in-system
programming algorithm results in issuance of an internal
device reset that causes OE/RESET to pulse Low.
External Programming
Xilinx reprogrammable PROMs can also be programmed by
the Xilinx MultiPRO Desktop Tool or a third-party device
programmer. This provides the added flexibility of using
pre-programmed devices with an in-system programmable
option for future enhancements and design changes.
