DESCRIPTION
The DS17485/DS17487 are real-time clocks (RTC) designed as successors to the industry standard DS1285, DS1385, DS1485, DS1585, and DS1685 PC real-time clocks. These devices provide the industry standard DS1285 clock function with either +3V or +5V 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 4kB of additional NV RAM, and 32.768kHz output for sustaining power management activities.
