DETAILED DESCRIPTION

The DS1689/DS1693 are real-time clocks (RTCs) designed as successors to the industry standard DS1285, DS1385, DS1485, and DS1585 PC real-time clocks. These devices provide the industry standard DS1285 clock function with the new feature of either +3.0V or +5.0V operation and automatic backup and write protection to an external SRAM. The DS1689 also incorporates a number of enhanced features including a silicon serial number, power-on/off control circuitry, and 114 bytes of user NV SRAM, power-on elapsed timer, and power-cycle counter.
