Compatible With High-ESR Crystals While Offering The Lowest Possible Current

The DS1341 DS1342 low-current Real-Time Clocks (RTCs) are timekeeping devices that provide an extremely low standby current, which permits longer life from a power supply. The DS1341 DS1342 support high-ESR crystals, which broaden the pool of usable crystals for the devices. The DS1341 uses a 6pF crystal, while the DS1342 uses a 12.5pF crystal. These devices are accessed through an I²C serial Interface Other features include two time-of-day alarms, two interrupt outputs, a programmable square-wave output, and a serial bus timeout mechanism.
