Application Scenarios & Design Considerations

Serial Access Real-Time Clock

Alternative Part Number

  • DS1307Z+ --: I2C real-time clock in an 8-pin SOIC package with similar function and pinout, widely available and a common drop-in style replacement for the M41T00.
  • PCF8563T/5,518 --: Low-power I2C RTC in SO-8 with comparable register interface and supply range, suitable as a functional alternative.
  • ISL1208IB8Z --: I2C real-time clock with integrated crystal compensation in an 8-pin SOIC, offering similar functionality for timekeeping applications.
  • RX8025T-UC --: I2C serial RTC in a similar small package with built-in crystal, offering equivalent timekeeping features and good availability as an alternative source.
