FAQ about Clock/Timing - Real Time Clocks
-
1. How accurate is the real-time clock?
The accuracy of RTC usually depends on the clock source used (such as a crystal oscillator), and most RTC accuracies range from a few seconds to a few minutes per month. For higher precision, a temperature compensated crystal oscillator (TCXO) can be used.
-
2. Can real-time clocks be used to set timers or alarms?
Yes, many RTC chips have built-in alarm functions that can trigger interrupts at set times to perform specific tasks or wake up the system.
-
3. How to choose a suitable RTC chip?
When choosing RTC, factors such as power consumption, communication interface (I2C/SPI), time accuracy, whether there is a built-in crystal or external crystal required, battery support, temperature range, and whether there is an alarm function should be considered.
