Real Time Clock Procurement Notes

Verify availability status as distribution may be restricted in certain regions. Confirm packaging options such as Reel or Cut Tape with the supplier. Ensure the specific suffix matches project requirements for pin configuration and output signals before ordering.

Real Time Clock Selection Notes

Select this model when a low-power RTC with SPI connectivity is required. The +/-3 PPM accuracy suits applications needing moderate precision without external calibration. Verify that the system voltage falls within the 1.6V to 5.5V range and that the operating environment stays within the specified temperature limits.

Real Time Clock Part Context

This part belongs to the RX4901CE family of real-time clocks manufactured by Epson Timing. The series offers various interface options and accuracy levels. The RX4901CE specifically targets applications requiring reliable timekeeping with digital serial communication capabilities.

Real Time Clock Replacement Considerations

Check datasheets for compatible alternatives within the same family or from other manufacturers. Ensure pin compatibility and electrical specifications match. Verify that any substitute supports the required 4-wire SPI protocol and temperature range.
