Really? 0.75-1W for an RTC that has a standby mode based on a coin cell? That sounds crazy! It's an SO8 package - can that even dissipate that much power?! Soun

Really? 0.75-1W for an RTC that has a standby mode based on a coin cell? That sounds crazy! It's an SO8 package - can that even dissipate that much power?! Sounds double-crazy!! Oh, wait, datasheet says its 0.0015mW max. https://cdn.sparkfun.com/datasheets/Dev/Beagle/DS3231M.pdf https://cdn.sparkfun.com/datasheets/Dev/Beagle/DS3231M.pdf And 1 Watt would make the part run at 120˚C above ambient.

> Oh, wait, datasheet says its 0.0015mW max I think you mean 1.5mW.

  Whoops, thanks. I actually meant 0.0015 W to keep the units the same.

Ouch! Sorry for that blunder, of course I misread the datasheet... Yeah it's totally unrealistic!
