General Description  
Features  
The DS1308 serial real-time clock (RTC) is a low-power,  
full binary-coded decimal (BCD) clock/calendar plus  
56 bytes of NV RAM. Address and data are transferred  
S Low Timekeeping Current of 250nA (typ)  
S Compatible with Crystal ESR Up to 100kω  
S RTC Counts Seconds, Minutes, Hours, Date,  
Month, Day of the Week, and Year with Leap-Year  
Compensation Up to 2400  
2
serially through an I C interface. The clock/calendar  
provides seconds, minutes, hours, day, date, month,  
and year information. The end of the month date is auto-  
matically 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 an AM/PM  
indicator. The DS1308 has a built-in power-sense circuit  
that detects power failures and automatically switches to  
the backup supply, maintaining time and date operation.  
S 56-Byte, Battery-Backed, General-Purpose RAM  
with Unlimited Writes

S I C Serial Interface  
S External Clock Source for Synchronization Clock  
Reference (e.g., 32kHz, 50Hz/60Hz Powerline, GPS  
1PPS)  
S Programmable Square-Wave Output Signal  
S Automatic Power-Fail Detect and Switch Circuitry  
S -40NC to +85NC Operating Temperature Range  
S Underwriters Laboratories (UL) Recognized
