<trans oldtip="A real time clock, or RTC, is a digital clock with a primary function to keep accurate track of time even when a power supply is turned off or a device is placed in low power mode. RTC’s are comprised of a controller, oscillator, and an embedded quartz crystal resonator. They are engineered as all-in-one devices to provide better performances than discrete components, simplify integration in new designs, and accelerate time to market." newtip="实时时钟(RTC)是一种数字时钟，其主要功能是即使在电源关闭或设备处于低功耗模式时也能准确跟踪时间。RTC由控制器、振荡器和嵌入式石英晶体谐振器组成。它们被设计为一体式器件，提供比分立器件更好的性能，简化新设计中的集成，并加快上市时间。">实时时钟(RTC)是一种数字时钟，其主要功能是即使在电源关闭或设备处于低功耗模式时也能准确跟踪时间。RTC由控制器、振荡器和嵌入式石英晶体谐振器组成。它们被设计为一体式器件，提供比分立器件更好的性能，简化新设计中的集成，并加快上市时间。trans>
<trans oldtip="Functions of the RTC are called registers. Register data is programmed into RAM memory. The registers are updated periodically – even during normal RTC operation. The RTC design also includes a power switch function to battery operation or another low power backup power source. This allows the RTC to maintain precise and continuous time counts even if the unit goes into sleep mode or if main power is lost. It also alleviates the need for the user to reset the time and date every time the device supply is cycled." newtip="RTC的功能称为寄存器。寄存器数据被编程写入RAM存储器。寄存器会定期更新，即使在正常RTC操作期间也是如此。RTC设计还包括电池供电的电源开关功能或另一个低功率备用电源。这样，即使设备进入睡眠模式或主电源断电，RTC也能保持精确和连续的时间计数。它还减少了用户在每次器件电源循环时重置时间和日期的需要。">RTC的功能称为寄存器。寄存器数据被编程写入RAM存储器。寄存器会定期更新，即使在正常RTC操作期间也是如此。RTC设计还包括电池供电的电源开关功能或另一个低功率备用电源。这样，即使设备进入睡眠模式或主电源断电，RTC也能保持精确和连续的时间计数。它还减少了用户在每次器件电源循环时重置时间和日期的需要。trans>
