2 I C RTC with Trickle Charger DS1340 General Description Benefits and Features The DS1340 is a real-time clock (RTC)/calendar that is Enhanced Second Source for the ST M41T00 pin compatible and functionally equivalent to the ST Completely Manages All Timekeeping Functions M41T00, including the software clock calibration. The RTC Counts Seconds, Minutes, Hours, Day, Date, device additionally provides trickle-charge capability Month, and Year on the V pin, a lower timekeeping voltage, and BACKUP Software Clock Calibration an oscillator STOP flag. Block access of the register Oscillator Stop Flag map is identical to the ST device. Two additional regis- Low-Power Operation Extends Battery Backup Run ters, which are accessed individually, are required for Time the trickle charger and flag.
