COM-10079

Overview

The SparkFun Electronics COM-10079 is a breakout board featuring the DS3234 real-time clock integrated circuit. It provides precise timekeeping capabilities with an integrated crystal oscillator and battery-backed RAM for data retention during power loss. The component utilizes a serial peripheral interface (SPI) for communication, supporting standard SPI modes. It operates within a voltage range of 2.7V to 5.5V and is housed in a 20-pin SOIC package.

Feature Summary

• Integrates high-precision real-time clock with calendar functionality
• Includes battery-backed SRAM for non-volatile data storage
• Features integrated temperature-compensated crystal oscillator
• Supports standard serial peripheral interface communication

Applications

• Data logging systems requiring accurate timestamping
• Embedded devices needing reliable timekeeping
• IoT nodes with low-power operation requirements
• Industrial control systems monitoring temporal events

Procurement Notes

Verify that the specific revision of the COM-10079 breakout board matches the required pinout configuration for your PCB design. Confirm compatibility with your system's SPI voltage levels, as the board supports both 3.3V and 5V logic depending on the jumper settings. Ensure the selected supplier provides genuine SparkFun components to guarantee the integrity of the DS3234 IC and associated passive components.

Selection Notes

Select this module when a complete RTC solution with minimal external components is preferred over discrete IC implementation. It is suitable for applications where space constraints limit the use of larger modules but require more robust timekeeping than software-based counters. Consider the SPI interface requirement versus I2C alternatives if bus availability is limited.

Part Context

This part is a specialized development tool manufactured by SparkFun Electronics, designed to simplify the integration of the DS3234 RTC into prototyping environments. It serves as an accessible entry point for engineers implementing time-sensitive functions without managing complex analog signal conditioning or external crystal calibration typically required for standalone RTC chips.

Replacement Considerations

For direct functional replacement, consider other breakout boards utilizing the same DS3234 IC from different manufacturers. If I2C interface is required instead of SPI, evaluate modules based on the DS3231 RTC, noting the difference in communication protocol and potential firmware adjustments.
