DETAILED DESCRIPTION

The DS1685/DS1687 are real-time clocks (RTC) designed as successors to the industry-standard DS1285,

DS1385, DS1485, and DS1585 PC RTCs. These devices provide the industry-standard DS1285 clock function with

either +3.0V or +5.0V 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 32.768kHz output for sustaining

power management activities.

The DS1685/DS1687 power-control circuitry allows the system to be powered on by an external stimulus such as a

keyboard or by a time and date (wake-up) alarm. The PWR output pin can be triggered by one or either of these

events, and can be used to turn on an external power supply. The PWR pin is under software control, so that when

a task is complete, the system power can then be shut down.

The DS1685 is a clock/calendar chip with the features described above. An external crystal and battery are the

only components required to maintain time-of-day and memory status in the absence of power. The DS1687

incorporates the DS1685 chip, a 32.768kHz crystal, and a lithium battery in a complete, self-contained timekeeping

EDIP. The entire unit is fully tested at Maxim such that a minimum of 10 years of timekeeping and data retention in

the absence of VCC is guaranteed
