DESCRIPTION
The DS1685/DS1687 is a real time clock (RTC) designed as a successor to the industry standard DS1285,
DS1385, DS1485, and DS1585 PC real time clocks. This device provides the industry standard DS1285
clock function with either +3.0 or +5.0-volt operation.
The DS1685 also incorporates a number of
enhanced features including a silicon serial number, power on/off control circuitry, 242 bytes of user
NV SRAM and 32.768 kHz output for sustaining power management activities.
