The RST pin is monitored as a pushbutton input for generating a microprocessor reset. A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output. In addition, RST pin is monitored as generating a µP reset. The DS3231 RTC IC with communication over I2C Interface. DS3231 RTC IC is that it has integrated crystal oscillator and temperature sensor and hence you don’t have to connect an external crystal. DS3231 is available in the same footprint as the popular DS3231 RTC. The RTC maintains seconds, minutes, hours, day, date, month, and year information. DS3231 RTC module can work on either 3.3V or 5V.
