DS1339B  
Low-Current, I C, Serial Real-Time Clock  
for High-ESR Crystals  
General Description  
The DS1339B serial real-time clock (RTC) is a low-  
power clock/date device with two programmable time-  
of-day alarms and a programmable square-wave output.

bus. The clock/date provides seconds, minutes, hours,  
day, date, month, and year information. The date at the  
end of the month is automatically adjusted for months  
with fewer than 31 days, including corrections for leap  
year. The clock operates in either the 24-hour or 12-hour  
format with AM/PM indicator. The device has a built-in  
power-sense circuit that detects power failures and auto-  
matically switches to the backup supply, maintaining time,  
date, and alarm operation.
