Other Parts Discussed in Thread: MSP432E401Y
MSP432E401Y Launchpad User Guide (SLAU748B) Sec 2.2.2 says:
"The Ethernet LaunchPad development kit can achieve microcontroller current consumption modes under 2 µA [sic] using hibernate VDD3ON mode. Hibernation with VDD3ON mode is not supported on this board."
When I read this a few months ago, only the second sentence stuck in my head. When I tried to figure out why, I noticed:
1) These two sentences apparently contradict one another.
2) Given that the /HIB pin is DNP (TP9) on the Launchpad -- notably, not connected to any regulator -- it seems as though VDD3ON is the Only hibernation mode that can be used on the Launchpad [Ref TRM (SLAU723A) Sec 6.3.3].
3) According to data sheet (SLASEN5) Sec 5.10, VDD3ON can only achieve about 8uA. (We can actually live with that.)
I think I know the answer already ("with the Launchpad, use VDD3ON mode"), but I thought I ought to check my reading before spending a couple of days trying to demonstrate hibernate mode.
