Xilinx XC1701SO20I

OTP1 Мб4,5 В ~ 5,5 В

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. The FPGA generates the appropriate number of clock pulses to complete the configuration. After 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. 

For device programming, either the Xilinx Alliance or Foundation software compiles the FPGA design file into a standard Hex format, which is then transferred to most commercial PROM programmers.
