ISD2110YYIR

Voice Record And Playback Overview

The ISD2110YYIR is a digital ChipCorder audio DSP from Nuvoton Technology Corporation, designed for single-chip high-quality audio storage and playback. It features 30 seconds of recording duration based on 8kHz/4bit ADPCM compression within 1Mbit of flash memory. The device operates at a supply voltage of 2.7V to 3.6V and supports sampling frequencies ranging from 4kHz to 32kHz. It integrates a Class D speaker driver capable of delivering up to 500mW into a 4Ω load or 330mW into an 8Ω load at 3V. Control is managed via a standard SPI interface or through six configurable GPIO pins for standalone operation. The component is housed in a 20-lead QFN package with an exposed pad.

Voice Record And Playback Feature Summary

• Integrated digital de-compression and Class D speaker driver for direct audio output without external components
• Non-volatile flash storage supporting voice prompts, voice macros, and user data sectors
• Flexible control options via SPI serial interface or standalone GPIO trigger configurations
• Internal factory-trimmed oscillator eliminating the need for external clock sources

Voice Record And Playback Applications

• Voice prompts for industrial equipment and appliances
• Sound effects modules for consumer electronics and toys
• Standalone audio messaging systems requiring minimal microcontroller interaction
• Security alarm systems and smart home devices

Voice Record And Playback Procurement Notes

Verify the specific ordering suffix YYIR against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with the host system's SPI voltage levels and GPIO configurations. Check for any recent revisions to the ISD2100 series documentation that may impact pinout or electrical characteristics relative to older batches.

Voice Record And Playback Selection Notes

Select this component when a dedicated audio solution with integrated storage and amplification is required. It is suitable for applications needing up to 30 seconds of audio with variable sample rates. Consider the GPIO flexibility if standalone triggering is preferred over continuous MCU polling. Verify power supply constraints align with the 2.7V to 3.6V operating range.

Voice Record And Playback Part Context

The ISD2110YYIR belongs to the ISD2100 series of ChipCorder devices. This family includes variants like the ISD2130 and ISD2115A, which differ primarily in storage capacity and resulting audio duration. The series is characterized by its ability to store multiple voice prompts and execute complex playback sequences via voice macros without external memory controllers.

Voice Record And Playback Replacement Considerations

Direct replacements within the same series include the ISD2130YYIR for extended duration or ISD2115AYYI for reduced size. Cross-series migration requires careful review of pin compatibility and software command sets. Verify that alternative packages (e.g., SOP-14) meet the physical space requirements of the existing design.
