XC17S150APD8I

Overview

The XC17S150APD8I is a serial configuration PROM designed for Xilinx FPGAs, specifically the XC2S150 series. It provides non-volatile storage for FPGA configuration data in an 8-pin DIP package. The device supports industrial temperature ranges and interfaces via standard serial protocols to load bitstreams into the target FPGA upon power-up.

Feature Summary

• Provides reliable non-volatile storage for FPGA configuration bitstreams
• Supports serial interface for compact board layout and simplified wiring
• Designed for industrial temperature operation to ensure stability in demanding environments

Applications

• Configuration memory for Xilinx Spartan-II XC2S150 FPGAs
• Industrial control systems requiring robust FPGA initialization
• Embedded applications needing persistent configuration storage

Procurement Notes

Verify component authenticity through authorized AMD/Xilinx distributors. Confirm package type matches the required 8-DIP form factor. Check revision history for any manufacturing updates that may affect compatibility with specific FPGA revisions. Ensure environmental ratings meet the operational requirements of the target application.

Selection Notes

Select this part when using Xilinx Spartan-II devices requiring external configuration storage. Compare pinout compatibility with existing PCB layouts. Consider lifetime status as the source indicates obsolescence; evaluate long-term supply availability for production runs before finalizing design choices.

Part Context

This component belongs to the Xilinx configuration PROM family, historically used to store bitstream data for Spartan-II FPGAs. It serves as a critical initialization element in designs where internal block RAM is insufficient or volatile storage is unacceptable for maintaining configuration across power cycles.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the stated obsolete lifecycle status, direct replacements may require redesigning the configuration circuitry or sourcing from secondary markets.
