Description
The DS3231 is an I2C real-time clock with a temperature-compensated crystal oscillator and crystal. It operates with a VCC of 2.3V to 5.5V and has features such as a temperature sensor, alarms, and a 32.768 kHz output pin for improved accuracy compared to the DS1307.
The DS3231 is an extremely accurate I2C real-time clock with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The DS3231 function with a VCC ranging from 2.3V to 5.5V. In comparison to the DS1307, the DS3231 has an integrated crystal, temperature sensor, 2 programmable time-of-day alarms, a 32.768 kHz output pin to ensure higher accuracy.
