XC18V02VQ44C

Overview

The XC18V02VQ44C is a 2-Mbit (256K x 8) In-System Programmable (ISP) PROM designed for Xilinx FPGA configuration. It operates with a supply voltage range of 2.7V to 3.6V and features a maximum access time of 20ns. The device utilizes CMOS technology and supports both parallel and serial programming interfaces. It is housed in a 44-pin TQFP package and is rated for commercial temperature ranges.

Feature Summary

• Supports In-System Programming for flexible field updates
• Non-volatile storage retains configuration data without power
• Compatible with standard Xilinx FPGA configuration protocols

Applications

• Configuration memory for Xilinx Virtex and Spartan FPGAs
• Industrial control systems requiring reliable FPGA boot sequences
• Telecommunications infrastructure equipment

Procurement Notes

Verify the component status as obsolete through official AMD channels. Confirm package integrity and pin compatibility with existing PCB footprints. Ensure the specific suffix matches required environmental ratings. Request original manufacturer documentation to validate authenticity before integration into production designs.

Selection Notes

Select this part when designing systems requiring non-vatile FPGA configuration storage with ISP capabilities. Verify that the target FPGA family is supported by the XC18V02 series. Consider the 2-Mbit capacity limits against the bitstream size requirements of the intended application logic.

Part Context

Part of the XC1800 family of configuration PROMs from Xilinx, now under AMD. These devices serve as primary configuration sources for various Xilinx programmable logic families, enabling reliable system initialization and reconfiguration capabilities in embedded applications.

Replacement Considerations

Check for direct cross-references within the XC18V02 family. Verify pin-to-pin compatibility if substituting with other 44-pin configuration memories. Consult AMD's obsolescence notices for recommended alternative components.
