MAX31343EKA+

Real Time Clock Overview

The MAX31343EKA+ is an I2C real-time clock (RTC) manufactured by Analog Devices Inc./Maxim Integrated. It integrates a MEMS oscillator to achieve ±5ppm accuracy without external crystals. The device operates within a supply voltage range of 1.6V to 3.6V and supports backup switching for continuous timekeeping during power loss. It provides calendar and time functions in YY-MM-DD-dd and HH:MM:SS formats, housed in an 8-ball wafer-level package (WLP).

Real Time Clock Feature Summary

• Integrated MEMS oscillator eliminates need for external crystal components.
• High accuracy of ±5ppm over temperature range.
• I2C serial interface for system communication.
• Backup switching capability ensures uninterrupted operation.

Real Time Clock Applications

• Portable electronic devices requiring precise timekeeping.
• Battery-powered systems with limited space constraints.
• Industrial equipment needing reliable RTC functionality.

Real Time Clock Procurement Notes

Verify the specific suffix EKA+ against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB layout for WLP-8 footprint. Confirm availability through authorized distributors as stock levels fluctuate.

Real Time Clock Selection Notes

Select this component when board space is limited and external crystals are undesirable. Compare against standard crystal-based RTCs if higher accuracy or different interface requirements exist. Validate voltage levels match the target system's 1.6V–3.6V operating range.

Real Time Clock Part Context

This part belongs to the MAX3134x family of low-power RTCs featuring integrated MEMS technology. It serves as a modern alternative to traditional quartz-based RTCs like the DS3231, offering similar I2C compatibility but with reduced component count and size due to the on-chip oscillator.

Real Time Clock Replacement Considerations

Direct pin-to-pin replacements may be limited. Consider the MAX31343EKA+T for tape-and-reel packaging or other variants in the MAX3134x series if package differences are acceptable. Verify electrical parameters against legacy parts like the DS3231M+.
