XC17S40XLPD8I

Configuration PROMs For FPGAs Overview

The XC17S40XLPD8I is a programmable read-only memory (PROM) component manufactured by AMD, designed specifically for configuring Field Programmable Gate Arrays (FPGAs). It features a storage capacity of 400 kilobits and utilizes One-Time Programmable (OTP) technology. The device operates within a supply voltage range of 4.5V to 5.5V and supports an industrial operating temperature range from -40°C to +85°C. It is housed in an 8-pin Plastic Dual In-line Package (PDIP) with a standard 0.300-inch (7.62mm) width, intended for through-hole mounting on printed circuit boards.

Configuration PROMs For FPGAs Feature Summary

• Provides non-volatile configuration data storage for Spartan FPGA families
• Utilizes one-time programmable architecture for permanent data retention
• Supports standard 5V logic levels for direct interface compatibility

Configuration PROMs For FPGAs Applications

• Configuration of Xilinx Spartan FPGA devices
• Industrial control systems requiring reliable boot-up sequences
• Embedded hardware initialization circuits

Configuration PROMs For FPGAs Procurement Notes

Verify the exact suffix designation carefully, as variations such as 'I' denote specific temperature ranges. Confirm RoHS compliance status, as older OTP PROM variants often lack modern environmental certifications. Check current availability as this component family may be subject to discontinuation notices or limited stock conditions due to its age.

Configuration PROMs For FPGAs Selection Notes

Select this part when a dedicated configuration PROM is required for Spartan series FPGAs rather than using internal block RAM or external serial flash. Ensure the design accommodates the 8-DIP footprint and that the programming equipment supports the specific voltage requirements for OTP burning. Consider lifecycle implications given the mature nature of this technology.

Configuration PROMs For FPGAs Part Context

This component belongs to the XC17S00/XL Spartan/XL family of configuration PROMs. These devices were historically essential for storing the bitstream data loaded into FPGAs at power-on. They represent a legacy solution compared to modern serial configuration options but remain relevant for maintaining existing designs.

Configuration PROMs For FPGAs Replacement Considerations

Direct pin-compatible replacements are scarce due to the specific OTP characteristics. Verify if newer Spartan devices support internal configuration via JTAG or external serial EEPROMs, which may eliminate the need for this parallel PROM entirely.
