FAQ

What is the primary function of the XC17128EPDG8C in FPGA-based systems?

The XC17128EPDG8C serves as a dedicated serial configuration PROM for Xilinx Virtex-E and Spartan-II FPGAs. It stores and delivers the FPGA bitstream at power-on or during in-system programming. Its 128 Kb capacity, 5 V operation, and 10 ns access time ensure reliable, timing-compliant initialization without external logic. The XC17128EPDG8C is optimized for direct integration into legacy Xilinx configuration chains.

Does the XC17128EPDG8C support in-system programming (ISP)?

Yes, the XC17128EPDG8C supports in-system programming via its serial interface (CS#, SK, DI, DO). It accepts new configuration data under 5 V supply using standard Xilinx programming protocols. Programming requires a compatible controller or Xilinx impact tool with appropriate adapter. The XC17128EPDG8C retains programmed data for 20 years at +85°C and withstands 100,000 write/erase cycles.

Is the XC17128EPDG8C pin-compatible with earlier Xilinx XC1700 series PROMs?

Yes, the XC17128EPDG8C uses the same SOIC-8 pinout and electrical interface as the Xilinx XC17128PC8 and XC1764 series, enabling direct PCB-level replacement. Signal definitions (CS#, SK, DI, DO, VCC, VSS) match JEDEC-standard assignments. The XC17128EPDG8C maintains identical timing and voltage thresholds, eliminating layout changes when upgrading from legacy Xilinx PROMs.

What temperature range is specified for the XC17128EPDG8C?

The XC17128EPDG8C is rated for industrial operation from –40°C to +85°C. This range is fully tested and guaranteed per JEDEC JESD22-A108 qualification standards. The device maintains 10 ns access time and valid read/write functionality across the full range. The XC17128EPDG8C is commonly deployed in factory automation, outdoor telecom, and avionics applications where ambient thermal extremes occur.

Can the XC17128EPDG8C be used with modern Xilinx 7-series or UltraScale FPGAs?

No, the XC17128EPDG8C is not compatible with Xilinx 7-series or UltraScale FPGAs. It is designed exclusively for Virtex-E, Spartan-II, and related legacy families that use the XC1700-series serial configuration protocol. Modern FPGAs require different configuration modes (e.g., SelectMAP, JTAG, or QSPI flash interfaces). The XC17128EPDG8C lacks the voltage tolerance, command set, and timing structure required for newer architectures.
