ISD2110AYYI

Overview

The ISD2110AYYI is a digital ChipCorder audio component manufactured by Nuvoton Technology Corporation. It provides single-chip storage and playback of high-quality audio using flash memory, offering up to 30 seconds of duration based on 8kHz/4bit ADPCM compression. The device features an internal oscillator, SPI interface for control, and integrated Class D speaker driver capable of delivering power to an 8Ω load. Operating voltage ranges from 2.7V to 3.6V, with an industrial temperature range of -40°C to 85°C. It is housed in a 20-WQFN exposed pad package.

Feature Summary

• Integrated flash storage for non-volatile audio playback without external components
• Supports standalone operation via GPIO triggers or microprocessor control through SPI interface
• Includes internal oscillator trimmed at manufacturing for accurate sample rates
• Features voice macro scripting for customizable playback sequences and configuration

Applications

• Voice prompts in consumer electronics
• Sound effects generation for user interfaces
• Standalone audio message systems
• Industrial notification devices

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability through authorized distributors as stock levels may vary. Ensure compatibility with existing system designs given the component's end-of-life status. Check for alternative sourcing options if long-term supply is required.

Selection Notes

Select this component when a compact solution for short-duration audio playback is needed. Consider the 20-QFN package size for space-constrained designs. Verify that the 30-second duration meets application requirements. Ensure the host system supports SPI communication or can utilize GPIO triggers for standalone operation.

Part Context

The ISD2110AYYI belongs to the ISD2100 series of ChipCorder devices. This series includes variants with different storage capacities, such as the ISD2130 with 30 seconds and ISD2115A with 15 seconds of audio duration. All members share similar architectural features including flash storage, SPI interface, and GPIO trigger capabilities.

Replacement Considerations

Check for direct substitutes within the ISD2100 family, such as ISD2130 or ISD2115A, depending on required audio duration. Evaluate pin-compatible alternatives if package constraints are strict. Verify functional equivalence regarding SPI commands and GPIO configurations when selecting replacements.
