Accurate 32.768KHz Crystal for Metering Applications

  2023-06-20


Have you ever pondered the significance of the mystical number 32768? Well, it all boils down to the utilization of a 32768Hz, or 32.768kHz, frequency for RTC/Timer purposes, which yields a precise 1-second delay. Remarkably, 32768 is a power of 2—specifically, 2 to the power of 15 equals 32768. Consequently, employing a 15-stage divider, we can effectively divide 32.768kHz into 1Hz, laying the foundation for achieving a 1-second period with ease.
