ISD2110AYYIR

Overview

The ISD2110AYYIR is a digital ChipCorder® providing single-chip storage and playback of high quality audio. The device features digital de-compression, comprehensive memory management, flash storage, and integrated audio signal path and Class D speaker driver capable of delivering power of 400mW . This family utilizes flash memory to provide non -volatile audio playback with duration up to 30 seconds ( based on 8kHz/4bit ADPCM compression) for a single -chip audio playback solution.

Feature Summary

• Integrated Class D speaker driver delivers 400mW output power.
• Supports standalone operation via GPIO triggers or SPI interface control.
• Includes Voice Macro scripting for customized playback sequences.
• Features internal oscillator trimmed to ±1% deviation.

Applications

• Voice prompts in consumer electronics
• Sound effects in smart toys
• Industrial alarm systems

Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging configuration. Confirm the component status as obsolete through official Nuvoton channels before finalizing procurement plans. Ensure compatibility with existing SPI programming tools.

Selection Notes

Select this model for applications requiring up to 30 seconds of audio duration at 8kHz/4bit ADPCM. Consider the QFN-20 package for compact designs. Evaluate the need for standalone GPIO triggering versus microcontroller-based SPI control when designing the system architecture.

Part Context

The ISD2110AYYIR belongs to the ISD2100 series of digital voice recorders. It shares core functionalities with the ISD2130 but offers specific storage configurations. The series is designed for simple integration into audio-enabled devices without external components.

Replacement Considerations

Check for ISD2130 variants if longer duration is required. Verify availability of newer ISD series replacements from Nuvoton for long-term supply assurance.
