17512LJC Overview
The XC1700 family of configuration PROMs provides an easy-to-use, cost-effective method for storing large 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.
