I am looking for a low power RTC, something like the DS1337 (400nA
timekeeping current) that has a non-inverted alarm interrupt.  The
interrupt is used to control a gate on a MOSFET (I'd prefer to not pull the
MOSFET gate high during non-interrupt periods).  I am working a very long
battery life problem (5 years) so I am trying to keep the parts count to a
bare minimum.  The RTC is used to power up the entire board, it runs off
unregulated battery between alarms (another nice thing about the DS1337,
Vcc up to 5.5V).

Any ideas?
