Virtex: Is it possible to remove Vccint while applying Vcco?

説明

Is it possible to remove Vccint while applying Vcco?

ソリューション

Yes, but with one caveat. 5.0V signals should not be supplied to the device for an extended period of time with VCCint un-powered (24 hours per year), or the lifetime will significantly decrease.

The ability to apply either one at a particular instant but not the other is supported to avoid issues with power sequencing; however, doing this over extended periods may affect the reliability of the device.
