Field Programmable Gate Array Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status as early production runs may vary. Ensure proper ESD handling procedures are followed during storage and installation. Validate that the specific speed grade (-8) meets the target timing requirements for the intended design application.

Field Programmable Gate Array Selection Notes

Select this model when designs require high-density logic resources combined with substantial embedded memory capacity. The -8 speed grade offers specific timing characteristics suitable for moderate-frequency synchronous applications. Consider the 1.8 V core voltage requirements and ensure adequate power delivery network design for the associated I/O supply voltages.

Field Programmable Gate Array Part Context

This component belongs to the Virtex-E family, representing an evolutionary step from the original Virtex series. It offers increased performance and lower power consumption due to the advanced 0.18 µm process technology. The architecture maintains pin compatibility with certain Virtex packages while introducing enhanced I/O flexibility and additional DLL resources.

Field Programmable Gate Array Replacement Considerations

The XCV1000E-6FG680C serves as a faster alternative within the same package and family. Designers migrating from the standard Virtex XCV1000 must account for architectural differences and recompile their bitstreams, as the devices are not bitstream-compatible despite physical similarities.

Field Programmable Gate Array FAQ

How does the Virtex-E architecture differ from the original Virtex family?

Virtex-E devices utilize a 0.18 µm process with a 1.8 V core voltage, offering up to 30% higher performance than the 2.5 V Virtex family. They also feature eight DLLs compared to four in Virtex devices and support additional I/O standards like LVPECL.

What is the maximum number of user I/Os available in the FG680 package?

According to the Virtex-E Family Maximum User I/O table, the FG680 package supports up to 512 user I/Os for the XCV1000E device.

Can input buffers for LVTTL and LVCMOS standards be powered by VCCO?

Yes, in Virtex-E devices, input buffers for LVTTL, LVCMOS2, and PCI standards are supplied by the I/O supply voltage VCCO rather than the internal VCCINT, allowing mixing of input and output buffers with the same VCCO.
