实时时钟
实时时钟（RTC）是一种集成电路（IC），用于时钟/定时应用，提供准确的时间跟踪能力。这些IC专门设计用于跟踪现实世界的时间，包括小时、分钟、秒钟，有时甚至包括日期和月份信息。
实时时钟通常由低功耗振荡器、计数器和一组用于存储时间和日期信息的寄存器组成。它们通常配备备用电源，如电池或超级电容器，以确保即使在断电情况下，时间仍然准确。
RTC的主要功能是持续跟踪时间的流逝，独立于外部电源。它们通常用于需要准确时间跟踪的电子设备，如计算机、嵌入式系统、通信设备和消费类电子产品，如数字手表和时钟。
RTC IC提供了多种功能来增强时间跟踪的准确性和功能性。这些功能可能包括自动闰年调整、夏令时支持、报警功能以及与外部时间参考（如GPS信号）的同步能力。
实时时钟可以通过各种接口（如I2C或SPI）与其他组件或微控制器进行通信，便于集成到更大的电子系统中。
总的来说，RTC在各种应用中发挥着至关重要的作用，提供准确可靠的时间跟踪，确保设备显示正确的时间并能够准确执行时间相关的功能。
