Description
The QPro™ series XQ1701L are Xilinx 3.3V high-density
configuration PROMs. The XQR1701L are radiation hard-
ened. These devices are manufactured on Xilinx QML certi-
fied manufacturing lines utilizing epitaxial substrates and
TID lot qualification (per method 1019).
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 D
IN
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.
Figure 1
shows a simplied block diagram.
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 Foun-
dation series development system compiles the FPGA
design file into a standard Hex format, which is then trans-
ferred to most commercial PROM programmers.
