串行实时时钟（RTC），内置电池切换电路

The M41T01 is a low-power serial real-time clock (RTC). The built-in 32.768 kHz oscillator circuit works with an external crystal and does not need any load capacitors.\n\n The M41T01 clock has a built-in power sense circuit which detects power failures and automatically switches to the battery supp • 2.0 to 5.5 V clock operating voltage \n• Counters for seconds, minutes, hours, day, date, month, years, and century \n• Software clock calibration \n• Automatic switchover and deselect circuitry \n• Ultra-low battery supply current of 800 nA \n• Low operating current of 300 μA \n• Battery and capa;
