XC18V512VQ44C

Overview

The AMD XC18V512VQ44C is a 512-kbit In-System Programmable (ISP) Configuration PROM designed for configuring Xilinx Field-Programmable Gate Arrays (FPGAs). It operates within a supply voltage range of 3.0V to 3.6V and supports an industrial operating temperature range of -40°C to +85°C. The device is housed in a 44-pin Very Thin Quad Flat Package (VQFP) with dimensions of 10x10 mm, suitable for surface-mount assembly.

Feature Summary

• Supports In-System Programming for FPGA configuration without removal from the board
• Provides non-volatile storage for FPGA bitstream data
• Compatible with standard ISP programming interfaces

Applications

• Configuration of Xilinx Virtex-II and Spartan-IIE FPGAs
• Industrial control systems requiring reliable FPGA initialization
• Telecommunications infrastructure equipment

Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence or third-party availability. Confirm package integrity and moisture sensitivity level handling procedures prior to soldering. Ensure compatibility with existing FPGA configuration controllers on the target design.

Selection Notes

Select this component when a 512-kbit capacity is required for FPGA configuration. Compare against the XC18V02 series if larger memory density is needed. Verify that the VQFP-44 package fits the PCB footprint constraints and thermal requirements of the application environment.

Part Context

This part belongs to the Xilinx XC18V00 series of configuration PROMs, which are widely used for storing configuration data for various Xilinx FPGA families. These devices enable flexible system updates and reduce initial hardware costs by allowing field reconfiguration.
