Overview
The DS3231MZ+TRL is a highly accurate, low-cost I2C real-time clock (RTC) produced by Analog Devices Inc./Maxim Integrated. This device is designed to provide precise timekeeping and is particularly notable for its integration of a microelectromechanical systems (MEMS) resonator, which enhances its long-term accuracy. The DS3231MZ+TRL maintains accurate timekeeping even when the main power is interrupted, thanks to its battery backup input. It is available in an 8-pin SOIC package and is footprint and functionally compatible with the popular DS3231 RTC.
