XC17S20XLPD8C

Overview

The XC17S20XLPD8C is a specialty memory circuit manufactured by Xilinx, housed in an 8-pin PDIP package. It features a memory density of 559232 bits with a width of 1 bit, resulting in 559232 words. The maximum clock frequency (fCLK) is 10 MHz. The component has a moisture sensitivity level of 1 and contains one functional unit. It is classified as a memory circuit under JESD-30 code R-PDIP-T8.

Feature Summary

• Specialty memory circuit designed for configuration data storage
• Operates with a single-bit memory width architecture
• Supports standard DIP packaging for through-hole mounting

Applications

• FPGA configuration memory storage
• System initialization data retention
• Embedded control logic programming

Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by Xilinx, not AMD. Confirm the specific suffix 'PD8C' matches the required PDIP8 package and temperature grade. Ensure compatibility with existing FPGA configuration interfaces before procurement.

Selection Notes

Select this part when a non-volatile configuration memory solution is required for Xilinx devices. Consider the 10 MHz clock limit and 559 kbit capacity against system requirements. Verify package availability and lead times due to potential obsolescence status common with older CPLD/FPGA configuration parts.

Part Context

This component belongs to the Xilinx Spartan-XL or similar era configuration PROM family. It serves as a serial configuration device for loading bitstreams into programmable logic. The technology represents earlier generations of flash-based configuration memory used in embedded systems.

Replacement Considerations

Check for direct pin-compatible substitutes within the Xilinx XC17xxx series. Verify if newer generation configuration devices offer backward compatibility. Consult official cross-reference guides for updated components replacing legacy configuration PROMs.
