DS3231 - I2C Real Time Clock (RTC) IC – SOP-16 Package

DS3231 - I2C Real Time Clock (RTC) IC – SOP-16 Package

The  DS3231  is  a  low-cost,  extremely  accurate  I2C  real-time clock (RTC) with an integrated temperature-compensated  crystal  oscillator  (TCXO)  and  crystal.  The device  incorporates  a  battery  input,  and  maintains  accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the  long-term  accuracy  of  the  device  as  well  as  reduces the piece-part count in a manufacturing line. The DS3231 is  available  in  commercial  and  industrial  temperature ranges, and is offered in a 16-pin, 300-mil SO package.
