• Provides non-volatile storage capability for holding configuration bitstreams required to initialize programmable logic devices.
• Constructed using CMOS technology within a compact, lead-free plastic quad flatpack package.

Applications

• Storing configuration data for Xilinx Field Programmable Gate Arrays (FPGAs)
• Programming Complex Programmable Logic Devices (CPLDs)
• Initializing embedded systems requiring persistent logic configuration

Procurement Notes

Verify the specific suffix 'VQG44C' against official AMD documentation to confirm the exact package variant and temperature grade. Ensure compatibility with the target FPGA's voltage requirements and interface mode. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Cross-reference the manufacturer part number with current datasheets to validate pinout and electrical specifications before procurement.

Selection Notes

Select this component when a high-density configuration memory is required for Xilinx programmable logic families. The choice depends on the need for 2M-bit capacity and support for both parallel and serial programming interfaces. Consider the VQFP-44 package constraints regarding board space and thermal management. Verify that the 20 ns access time meets the timing requirements of the target configuration controller.

Part Context

This component belongs to the Xilinx Platform Flash family, which serves as configuration memory for various Xilinx programmable logic devices. These devices are essential for storing the binary configuration files that define the hardware functionality of FPGAs and CPLDs upon power-up. The platform flash series provides reliable, non-volatile storage solutions integrated into the design flow for adaptive computing systems.

Replacement Considerations

Consult official AMD substitution guides for verified equivalents. Generic cross-references may not match the specific interface timing or voltage characteristics required for reliable configuration.
