It offers a storage capacity of 4Mbit (512K x 8) and supports both parallel and serial interfaces. The device features a 20ns access time and is housed in a 44-pin VQFP package. It provides high durability with 20,000 programming/erase cycles and supports dual configuration modes.

Feature Summary

• In-System Programmability for flexible FPGA configuration updates
• Supports both parallel and serial CMOS interface modes
• High endurance rated for 20,000 programming and erase cycles

Applications

• Configuration memory for Xilinx FPGAs
• Dual configuration mode systems
• Low power embedded applications requiring reprogrammable storage

Procurement Notes

Verify the specific suffix 'VQG44C' to confirm the 44-pin VQFP package and commercial temperature grade. Ensure compatibility with the target FPGA's voltage requirements, as this device operates at 3.3V. Cross-reference the manufacturer's latest datasheet to confirm pinout and electrical specifications before integration.

Selection Notes

Select this component when a non-volatile configuration solution with high reprogrammability is required for Xilinx FPGAs. It is suitable for designs needing dual configuration support or frequent field updates. Consider the 44-pin VQFP footprint during PCB layout planning.

Part Context

This part belongs to the AMD/Xilinx XC18V04 series of configuration PROMs. These devices are specifically engineered to program volatile SRAM-based FPGAs, retaining configuration data without power. The series includes variants with different capacities and packages to suit various design constraints.

Replacement Considerations

Check for direct substitutes within the XC18V04 family, such as XC18V04VQG44I for industrial temperature range. Verify pin-to-pin compatibility and electrical characteristics before substituting with other configuration memory devices.
