DS1672
I
2C 32-Bit Binary Counter RTC
www.maxim-ic.com
GENERAL DESCRIPTION
The DS1672 incorporates a 32-bit counter and
power-monitoring functions. The 32-bit counter
is designed to count seconds and can be used to
derive time-of-day, week, month, month, and
year by using a software algorithm. A precision,
temperature-compensated
reference
and
comparator circuit monitors the status of VCC.
When an out-of-tolerance condition occurs, an
internal power-fail signal is generated that forces
the reset to the active state. When VCC returns to
an in-tolerance condition, the reset signal is kept
in the active state for a period of time to allow
the power supply and processor to stabilize.
