Timekeepers

ST’s TIMEKEEPER products add a quartz crystal, very-low-power oscillator and a clock/calendar circuit to provide real-time data. Advanced TIMEKEEPERs include additional features such as programmable alarms, watchdog timers, system reset outputs and battery-low warning flags.

To make designing with TIMEKEEPERS even easier, ST offers the following simulators:

• TIMEKEEPER battery life data
