DESCRIPTION  
The DS1680 incorporates many functions necessary for low-power portable products, providing an RTC,  
NV RAM controller, microprocessor monitor, power-fail warning, 10-bit ADC, and a touch-screen  
controller in one chip.  
The RTC provides seconds, minutes, hours, day, date, month, and year information with leap-year  
compensation as well as an alarm interrupt. This interrupt works when the DS1680 is powered by the  
system power supply or when in battery-backup operation, so the alarm can be used to wake up a system  
that is powered down.
