Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet before integration. Confirm that the required audio duration falls within the 140 to 420-second operational range. Ensure power supply requirements align with the specified 2.4 V to 5.5 V operating voltage. Check for availability as this component may have limited stock or be subject to end-of-life status.

Selection Notes

Select this component when long-duration voice recording is required compared to shorter variants in the same series. Consider the 28-DIP package if through-hole mounting is preferred over surface mount options. Evaluate the need for SPI versus pushbutton interface based on system complexity. Verify compatibility with existing microphone and speaker hardware specifications.
