Real Time Clock datasheet and documents for MAX6910EO33+

MAX6910EO33+

Real Time Clock Overview

The MAX6910EO33+ is an I2C-compatible real-time clock (RTC) with a microprocessor supervisor, NV RAM controller, and optional trickle charger. It provides timekeeping for seconds through year, including leap year compensation up to 2100. The device features 31 bytes of static RAM for scratchpad storage and operates on a 2-wire serial bus at 400kHz. Electrical characteristics specify an operating voltage range of 3.0V to 3.6V for the EO33 variant. It includes alarm outputs, crystal fail detection, and a piezo transducer driver. The component is housed in a 20-pin QSOP package and functions within a temperature range of -40°C to +85°C.

Real Time Clock Feature Summary

I2C-compatible RTC with 31-byte NV SRAM and programmable trickle charger
Microprocessor supervisor with open-drain reset output and watchdog timer
Alarm outputs and crystal fail indication via dedicated pins
Piezo transducer driver with selectable frequencies (1.024kHz to 8.192kHz)

Real Time Clock Procurement Notes

Verify the specific EO33 suffix indicates the 3.0V to 3.6V operating voltage range rather than the EO30 2.7V to 3.3V range. Confirm RoHS compliance status as indicated in official documentation. Check current availability status as distribution channels may report limited stock or end-of-life conditions for this Maxim Integrated part number.

Real Time Clock Selection Notes

Select the MAX6910EO33+ when system power rails operate between 3.0V and 3.6V. Ensure compatibility with standard 32.768kHz, 6pF load crystals. Verify that the required 31 bytes of non-volatile RAM are sufficient for application data storage needs. Confirm that the integrated microprocessor supervisor thresholds meet the system's reset requirements.

Real Time Clock Part Context

This component belongs to the MAX6909/MAX6910 family of I2C-compatible real-time clocks. The MAX6910 distinguishes itself from the MAX6909 by including an onboard programmable trickle charger for battery backup management. Both variants share identical RTC functionality, NV RAM capacity, and supervisor features, differing primarily in power management capabilities.
