We plan on using the RF430CL330H in one of our product designs (Li-Ion battery-powered).
Can this IC be operated with a 3.0V regulated supply instead of a 3.3V supply?
Many thanks.

Thanks - I see that 3.0V is the minimum.
I guess my question really is: What happens if the regulated 3V supply drops to say 2.95V or so?
most likely it will still work just fine, but we spec it at 3V over temp range...when we do characterization and qualification, we have to draw the line somewhere....:)
other example you can see here is the field powered version, which operates from handset field power exclusively - with the MCU and the RF430 both being powered up with weak or unpredictable voltage source,

this works great, and it gives confidence that dropping 0.05VDC below the min rating will most likely be no problem.
Thanks Josh.
You are right - that RF-field powered application does give some confidence that slightly lower voltages than 3V will still be OK for a bus-powered application.
Out of curiosity, do you know why is Vmin lower for the RF-field powered application? (3V vs 2V).
