±5ppm, I2C Real-Time Clock with Integrated MEMS Oscillator
General Description
The MAX31343 is a low-cost, extremely accurate, I2C real-time clock (RTC). The device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. The integration of the microelectromechanical systems (MEMS) resonator enhances the long-term accuracy of the device and eliminates the external crystal requirement in the system. The MAX31343 is available in the 8-pin WLP and TDFN packages.
The RTC maintains seconds, minutes, hours, day, date, month,...
