DS1338  
I2C RTC with 56-Byte NV RAM  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS1338 serial real-time clock (RTC) is a low-  
power, full binary-coded decimal (BCD)  
clock/calendar plus 56 bytes of NV SRAM. Address  
and data are transferred serially through an I2C  
interface. The clock/calendar provides seconds,  
minutes, hours, day, date, month, and year  
information. The end of the month date 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 DS1338 has a built-in power-  
sense circuit that detects power failures and  
automatically switches to the backup supply,  
maintaining time and date operation  
.
RTC Counts Seconds, Minutes, Hours, Date  
of the Month, Month, Day of the Week, and  
Year with Leap-Year Compensation Valid Up  
to 2100  
Available in a Surface-Mount Package with an  
Integrated Crystal (DS1338C)
