XC17S15ASO20C

Overview

The XC17S15ASO20C is a serial configuration PROM manufactured by AMD, designed for programming Xilinx Field-Programmable Gate Arrays (FPGAs). It features a 150kb memory capacity and utilizes One-Time Programmable (OTP) technology. The device operates within a supply voltage range of 3V to 3.6V. It is housed in a 20-SOIC package and is rated for commercial temperature operation.

Feature Summary

• Provides non-volatile storage for FPGA configuration data
• Utilizes one-time programmable architecture for secure bitstream retention
• Compatible with standard Xilinx FPGA initialization sequences

Applications

• Configuration of Xilinx Spartan and Virtex FPGA devices
• Industrial control systems requiring reliable FPGA boot-up
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix 'SO20C' to confirm the 20-pin SOIC package and commercial temperature grade. Confirm that the OTP nature of the device aligns with permanent configuration requirements, as data cannot be erased or rewritten after programming.

Selection Notes

Select this component when a dedicated serial PROM is required for Xilinx FPGA initialization rather than using internal block RAM. Ensure the 150kb capacity meets the size of the target design's configuration bitstream. Verify voltage compatibility with the FPGA's VCCO pins during startup.

Part Context

This part belongs to the AMD (formerly Xilinx) XC17S series of configuration PROMs. These devices are specifically engineered to store the binary configuration files necessary to initialize Xilinx FPGAs upon power-up, ensuring the device starts in the correct operational state.

Replacement Considerations

Check for direct pin-compatible substitutes within the XC17S family, such as other density variants if the bitstream size allows. Verify that any alternative maintains the same OTP characteristics and voltage specifications.
