02
Features
• Certified to MIL-PRF-38535 Appendix A QML
(Qualified Manufacturer Listing.)
• Also available under the following Standard Microcircuit
Drawings (SMD): 5962-94717 and 5962-95617.
• Configuration one-time programmable (OTP) read-only
memory designed to store configuration bitstreams of
Xilinx FPGA devices
• On-chip address counter, incremented by each rising
edge on the clock input
• Simple interface to the FPGA requires only one user
I/O pin
• Cascadable for storing longer or multiple bitstreams
• Programmable reset polarity (active High or active
Low) for compatibility with different FPGA solutions
• Low-power CMOS EPROM process
• Available in 5V version only
• Programming support by leading programmer
manufacturers.
• Design support using the Xilinx Alliance and
Foundation series software packages.
Product Specification
Description
The XC1700D QPRO™ family of configuration PROMs pro-
vide an easy-to-use, cost-effective method for storing Xilinx
FPGA configuration bitstreams.
When the FPGA is in Master Serial mode, it generates a
configuration clock that drives the PROM. A short access
time after the rising clock edge, data appears on the PROM
DATA output pin that is connected to the FPGA DIN pin. The
FPGA generates the appropriate number of clock pulses to
complete the configuration. Once configured, it disables the
PROM. When the FPGA is in Slave Serial mode, the PROM
and the FPGA must both be clocked by an incoming signal.
Multiple devices can be concatenated by using the CEO
output to drive the CE input of the following device. The
clock inputs and the DATA outputs of all PROMs in this
chain are interconnected. All devices are compatible and
can be cascaded with other members of the family.
For device programming, either the Xilinx Alliance™ or the
Foundation™ series development systems compiles the
FPGA design file into a standard HEX format which is then
transferred to most commercial PROM programmers.

Multiple devices can be cascaded to support additional FPGAs. An early DONE inhibits the PROM data output one CCLK
cycle before the FPGA I/Os become active.

Notes:
1. AC test load = 50 pF
2. All AC parameters are measured with VIL = 0.0V and VIH = 3.0V.
3. Guaranteed by design, not tested.
4. Float delays are measured with 5 pF AC loads. Transition is measured at ±200mV from steady state active levels.
