DESCRIPTION
The DS17485/DS17487 is a real time clock (RTC) designed as a successor to the industry standard
DS1285, DS1385, DS1485, DS1585, and DS1685 PC real time clocks. This device provides the industry
standard DS1285 clock function with either +3.0 or +5.0-volt operation. The DS17485 also incorporates
a number of enhanced features including a silicon serial number, power on/off control circuitry, 114 bytes
of user NV SRAM plus 4 kbytes of additional NV RAM, and 32.768 kHz output for sustaining power
management activities.
