The DS3231 is available in commercial and industrial temperature ranges and uses a 16-pin 300mil SO package.
DS3231 Clock Module mainly uses the high precision clock chip DS3231.
The device contains the battery input and can remain accurate when the main power is turned off. Temperature-compensation crystal oscillator improves the long-term accuracy of the device and reduces the number of components in the production line.
It is a low cost, high precision I2C real time clock (RTC) with integrated temperature-compensation crystal oscillator (TCXO) and crystal.
