XC17S20XLVO8I

Overview

The XC17S20XLVO8I is a specialty memory circuit manufactured by Rochester Electronics, functioning as a non-volatile configuration PROM. It features a memory density of 178,144 bits organized as 178,144 words by 1 bit. The device operates in synchronous mode and is housed in an 8-pin Plastic Dual In-line Package (PDIP-8). It supports a wide industrial operating temperature range from -40 °C to +85 °C.

Feature Summary

• Provides reliable non-volatile storage for FPGA configuration data
• Supports synchronous operation modes for system integration
• Engineered for robust performance across extended industrial temperature ranges

Applications

• Configuration storage for Xilinx FPGAs
• Industrial embedded systems requiring secure boot data
• Automotive electronics compliant with ISO 26262 standards

Procurement Notes

Verify the specific suffix 'V' indicates voltage or package variations against official datasheets. Confirm lead times and lot traceability directly with authorized distributors. Ensure compatibility with target FPGA devices before procurement.

Selection Notes

Select this component when a small-capacity, single-bit-wide configuration memory is required for Spartan or Artix series FPGAs. Consider the PDIP-8 package constraints for PCB layout and thermal management in enclosed industrial enclosures.

Part Context

This part belongs to the XC17xx family of configuration PROMs designed specifically for Xilinx programmable logic devices. These components store the bitstream data used to initialize the FPGA fabric upon power-up, ensuring deterministic system startup behavior.

Replacement Considerations

Check for XC17S20E or XC17S20 variants depending on voltage requirements. Verify pinout compatibility and ensure the replacement supports the same synchronous interface protocol.
