DS1672  
I2C 32-Bit Binary Counter RTC

GENERAL DESCRIPTION  
FEATURES  
The DS1672 incorporates a 32-bit counter and 32-Bit Counter  
I2C* Serial Interface  
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,  
Automatic Power-Fail Detect and Switch  
Circuitry  
Power-Fail Reset Output  
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.  
Low-Voltage Oscillator Operation
