I C RTC with Trickle Charger  
General Description  
Features  
♦ Enhanced Second Source for the ST M41T00  
The DS1340 is a real-time clock (RTC)/calendar that is  
pin compatible and functionally equivalent to the ST  
M41T00, including the software clock calibration. The  
device additionally provides trickle-charge capability  
♦ Available in a Surface-Mount Package with an  
Integrated Crystal (DS1340C)  
2
♦ Fast (400kHz) I C Interface  
on the V  
pin, a lower timekeeping voltage, and  
BACKUP  
♦ Software Clock Calibration  
an oscillator STOP flag. Block access of the register  
map is identical to the ST device. Two additional regis-  
ters, which are accessed individually, are required for  
the trickle charger and flag. The clock/calendar pro-  
vides seconds, minutes, hours, day, date, month, and  
year information. A built-in power-sense circuit detects  
power failures and automatically switches to the back-  
up supply. The device is programmed serially through  
♦ RTC Counts Seconds, Minutes, Hours, Day, Date,  
Month, and Year  
♦ Automatic Power-Fail Detect and Switch Circuitry  
♦ Trickle-Charge Capability  
♦ Low Timekeeping Voltage Down to 1.3V  
♦ Three Operating Voltage Ranges (1.8V, 3V, and 3.3V)  
♦ Oscillator Stop Flag

an I CTM bidirectional bus.  
♦ Available in 8-Pin µSOP or SO Packages  
♦ Underwriters Laboratory (UL) Recognized
