DS1344 (DS1343 / DS1344) Low-Current SPI/3-Wire RTCs

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. The clock/calendar prov.

DS1344 Features
