WebDec 8, 2024 · 12.1.3 High Precision XT Oscillator (XT) The high accuracy XT Oscillator is tuned to an external 32.768 kHz crystal, and has a nominal frequency of32.768 kHz. It is used when frequency accuracy is critically important. Because a crystal oscillator uses a significant amount of power, the XT is only enabled when an internal module is using it. WebThe difference between the two counts, over the high speed clocks frequency, is the ppm error rate of the rtc. Best of luck to your project.

WebMay 23, 2024 · The only difference between the DS3231 and the DS1307 is that the DS3231 has a temperature compensated crystal built-in, which makes it more precise, but the chip is also considerably bigger. They share the same I2C address, thus libraries designed for the DS1307 should also function for the DS3231. What is the address of DS1307?
