Is it possible to remove Vccint while applying Vcco?
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.
