Application Scenarios & Design Considerations

ZEROPOWER SNAPHAT (BATTERY)

Alternative Part Number

  • DS1338Z-33+ --: I2C real-time clock with integrated crystal and battery backup switchover, functionally similar to the M4Z28 serial RTC and widely available.
  • PCF8563T --: Low-power I2C real-time clock/calendar with battery backup support, a common drop-in style alternative for serial RTC applications.
  • RV-3028-C7 --: Ultra-low-power I2C RTC module with integrated crystal and backup switching, suitable replacement when high accuracy and low current are needed.
