XC17S40SO20I

Configuration PROMs For FPGAs Overview

The AMD XC17S40SO20I is a one-time programmable (OTP) configuration PROM designed for Field Programmable Gate Arrays (FPGAs). It provides 400 kilobits of non-volatile memory to store FPGA configuration data. The device operates within a supply voltage range of 4.5V to 5.5V and is rated for an industrial operating temperature range of -40°C to 85°C. It is housed in a 20-pin Small Outline Integrated Circuit (SOIC) package with a width of 7.50mm.

Configuration PROMs For FPGAs Feature Summary

• Provides non-volatile storage for FPGA configuration bitstreams via one-time programming technology.

Configuration PROMs For FPGAs Applications

• Configuration of Xilinx FPGAs

Configuration PROMs For FPGAs Procurement Notes

Verify the component status, as this specific part number may be classified as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure the OTP nature of the device aligns with production requirements, as data cannot be reprogrammed after initial writing.

Configuration PROMs For FPGAs Selection Notes

Select this component when a dedicated external configuration memory is required for compatible Xilinx FPGAs. Consider the 400kb capacity limit against the size of the target design's bitstream. Evaluate the 20-SOIC package constraints for PCB layout and ensure the system power supply remains stable within the 4.5V to 5.5V operational window.

Configuration PROMs For FPGAs Part Context

This component belongs to the AMD (formerly Xilinx) family of configuration PROMs. These devices serve as primary boot memory for FPGAs that do not utilize internal block RAM or external flash controllers for configuration. They are integral to systems requiring reliable, standalone FPGA initialization upon power-up.
