XC18V04VQ44I

Overview

The AMD XC18V04VQ44I is a 3.3V in-system programmable configuration PROM designed for storing Xilinx FPGA bitstreams. It features a 4-megabit memory capacity and supports both serial and parallel configuration modes. The device operates within a commercial/industrial temperature range of –40°C to +85°C and utilizes a low-power advanced CMOS FLASH process. It includes IEEE Std 1149.1 boundary-scan support and offers dual configuration options: Master/Slave Serial and Parallel modes.

Feature Summary

• Supports in-system programming via standard JTAG protocol for efficient design iterations
• Provides cascading capability through CEO output for storing longer or multiple bitstreams
• Features 5V tolerant I/O pins accepting 5V, 3.3V, and 2.5V signals
• Incorporates data security features to prevent unauthorized reading via JTAG

Applications

• Configuration of Virtex-II and Virtex-II Pro FPGAs
• Configuration of Spartan-II and Spartan-IIE FPGAs
• Configuration of Virtex-E and Virtex FPGAs

Procurement Notes

Verify the specific suffix 'VQ44I' corresponds to the 44-pin VQFP package and industrial temperature grade. Confirm the manufacturer origin as AMD/Xilinx given historical transitions. Ensure the component meets RoHS compliance requirements if applicable to your system specifications, noting that older revisions may be non-compliant.

Selection Notes

Select this component when a 4-megabit configuration memory is required for compatible Xilinx FPGAs. It is suitable for designs needing in-system reprogrammability and JTAG-based testing. Consider cascading with other XC18V00 series devices if larger storage capacity is needed. Verify voltage compatibility with the target FPGA's configuration interface.
