I love HN. I came here to learn more about MEMS RTCs, something I've never heard about previously... But most of the discussion is about the dangers of a helium leak... Which is a good point, especially if that leak is in a hospital.

A bit of googling on MEMS RTC revealed this slightly dated article which I thought was still interesting: https://www.maximintegrated.com/en/app-notes/index.mvp/id/55...

Turns out one of the main reasons to switch is for the smaller packaging vs quartz oscillators.
