ISD2110YYI

Voice Record And Playback Overview

The ISD2110YYI is a digital ChipCorder audio component from Nuvoton Technology Corporation, designed for single-chip storage and playback of high-quality audio. It features integrated flash memory providing up to 30 seconds of recording duration based on 8kHz/4bit ADPCM compression. The device operates within a voltage range of 2.7V to 3.6V and supports sampling frequencies of 4, 5.3, 6.4, 8, 12.8, 16, and 32 kHz. It includes an internal oscillator trimmed to ±1% deviation and utilizes variable-bit-rate optimized compression algorithms including µ-Law, Differential µ-Law, PCM, and Enhanced ADPCM. The unit is housed in a 20-lead QFN package with exposed pad.

Voice Record And Playback Feature Summary

• Supports standalone operation via GPIO triggers or microprocessor control through SPI interface
• Features Voice Macro scripting for customizable playback sequences and device configuration
• Includes non-volatile flash storage with sector erase capability and memory protection

Voice Record And Playback Applications

• Voice prompts for consumer electronics and appliances
• Sound effects modules for toys and interactive devices
• Industrial announcement systems requiring standalone audio playback
• Security alarm voice messages and warning indicators

Voice Record And Playback Procurement Notes

Verify the specific ordering suffix YYI against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with the intended host controller SPI settings and GPIO configurations before finalizing procurement orders.

Voice Record And Playback Selection Notes

Select this model when a fixed audio duration of approximately 30 seconds is required with minimal external circuitry. Consider the ISD2100 series variants if different storage capacities or package options are needed. Verify that the application environment falls within the specified industrial temperature range and voltage requirements.

Voice Record And Playback Part Context

This component belongs to the ISD2100 series of digital ChipCorder devices. The series provides a complete solution for audio prompting by integrating flash memory, compression/decompression logic, and audio output drivers into a single package, reducing system complexity compared to discrete solutions.

Voice Record And Playback Replacement Considerations

Check for direct cross-references within the ISD2100 family such as ISD2130YYIR for identical functionality but potentially different inventory status. Verify pinout compatibility if substituting with other audio ICs, as interface protocols and GPIO mappings may differ significantly between manufacturers.
