The XC3S1600E requires an 8 Mbit PROM. Two solutions
are possible: either a single 8 Mbit XCF08P parallel/serial
PROM or two 4 Mbit XCF04S serial PROMs cascaded. The
two XCF04S PROMs use a 3.3V V
XCF08P requires a 1.8V V
not already have a 1.8V supply available, the two cascaded
XCF04S PROM solution is recommended.
CCLK Frequency
In Master Serial mode, the FPGA’s internal oscillator gener-
ates the configuration clock frequency. The FPGA provides
this clock on its CCLK output pin, driving the PROM’s CLK
input pin. The FPGA starts configuration at its lowest fre-
quency and increases its frequency for the remainder of the
configuration process if so specified in the configuration bit-
stream. The maximum frequency is specified using the
ConfigRate
maximum ConfigRate settings, approximately equal to
MHz, for various Platform Flash devices and I/O voltages.
For the serial XCFxxS PROMs, the maximum frequency
also depends on the interface voltage.
