DS1672

I²C 32-Bit Binary Counter RTC

GENERAL DESCRIPTION

FEATURES

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,

and

comparator circuit monitors the status of V_CC.

When an out-of-tolerance condition occurs, an

internal power-fail signal is generated that forces

the reset to the active state. When V_CCreturns 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.
