DS12885S/T&R

The DS12885S/T&R real time clock is a highly accurate, programmable and reliable clock for a wide range of applications where accurate time keeping is required. The chip can be programmed to perform an array of activities, including setting alarms and providing an output pulse when a certain time is reached. It is also capable of counting seconds, minutes and hours. The DS12885S/T&R real time clock also provides an accurate and reliable means of Power Failure Detection and real-time clock functionality.

This real time clock is ideal for a wide range of industrial and commercial applications that require precise timing and power failure detection. It is capable of providing automated time keeping with hourly, daily, monthly and yearly registers. Clock accuracy is kept to within one percent of the battery reference voltage, providing reliable and accurate time keeping.

The DS12885S/T&R real time clock consists of a programmable watchdog timer (WDT), a microcontroller and various logic components. The microcontroller is programmed to count up to a preset time. When this time is reached, it generates an interrupt and stops the timer until it is reset. The watchdog timer monitors the system\'s clock and resets it if the clock fails to update itself within a certain period.

The real time clock allows the user to set alarms that can be set hourly, daily, monthly or yearly. The watchdog timer also allows the user to set a power-on alarm, which will trigger the system to reset itself if the power fails for a preset duration. This ensures that the system does not experience any unexpected events due to power issues.

The DS12885S/T&R real time clock is a highly reliable and accurate real time clock. Its features provide accurate time keeping and power failure detection that can be used in a variety of applications. Its features also make it ideal for industrial and commercial applications that require reliable and accurate time keeping.
