voltage)
 Deep software standby mode with RTC remaining usable
 Four low power modes
■ 24-bit ∆Σ A/D Converter
 SNDR = 85dB

 Year and month display or 32-bit second display (binary
counter) is selectable
 Time capture on event-signal input through external pins
 RTC capable of initiating return from deep software
standby mode
