    DS1343
    Low-Current SPI/3-Wire RTCs Low Timekeeping Current of 250nA (typ)
    
General Description
The DS1343/DS1344 low-current real-time clocks (RTCs) are timekeeping devices that provide an extremely low standby current, permitting longer life from a backup supply source. The devices also support high-ESR crystals, broadening the pool of usable crystals for the devices.
