ISD2130YYIR

Overview

The ISD2130YYIR is a digital audio playback device from the Nuvoton ISD2100 series, featuring 30 seconds of storage based on 8kHz/4bit ADPCM compression within 1Mbit flash memory. It operates on a supply voltage range of 2.7V to 3.6V with a maximum clock frequency and sampling rate of 32 kHz. The component utilizes an SPI interface for control and programming, housed in a QFN-20 package. It draws 5 mA during operation and functions reliably between -40°C and +85°C.

Feature Summary

• Integrated Class D speaker driver capable of delivering up to 400mW output power directly to speakers or buzzers without external components.
• Supports standalone operation through six GPIO pins configured as triggers for pre-programmed Voice Macro scripts.
• Includes non-volatile flash storage with 1Kbyte sector erasability and integrated memory checksum verification.
• Features internal oscillator trimmed to ±1% deviation, eliminating the need for external clock sources.

Applications

• Voice prompts and sound effects for user interfaces
• Audio guidance systems requiring multi-language support
• Low-power single-chip audio storage solutions

Procurement Notes

Verify the specific ordering suffix YYIR corresponds to the QFN-20 package and industrial temperature grade (-40°C to +85°C) required for your design. Confirm that the host system supports the standard four-wire SPI interface mode 3 for communication. Ensure power supply rails remain within the 2.7V to 3.6V operating range to maintain signal integrity and compliance with absolute maximum ratings.

Selection Notes

Select this model when 30 seconds of high-quality audio storage is sufficient for the application. The QFN-20 package is suitable for surface-mount assembly where space efficiency is prioritized over the SOP-14 alternative. Consider the integrated PWM driver if driving an 8Ω speaker directly, avoiding the need for external amplification circuitry.

Part Context

This component belongs to the ISD2100 series of ChipCorder devices, which provide single-chip digital audio storage and playback. The series includes variants like the ISD2115A with 15 seconds of storage and different packaging options such as SOP-14. All members share the same core architecture, including the Voice Macro scripting capability and SPI interface.

Replacement Considerations

The ISD2130SYI serves as a functional substitute offering identical electrical specifications and features but utilizes an SOP-14 package instead of QFN-20. Designers must account for pinout differences and footprint changes when transitioning between these package types.

FAQ

How is audio data addressed for playback?

Audio is stored as Voice Prompts addressed by a simple sequential index number rather than absolute memory addresses, allowing updates without changing host controller code.

Can the device operate without a microcontroller?

Yes, the device can operate stand-alone by assigning Voice Macros to its GPIO trigger pins, enabling autonomous playback sequences.

What compression algorithms are supported?

The device supports µ-Law, Differential µ-Law, PCM, and Enhanced ADPCM compression algorithms with variable bit rates optimized for SNR and noise levels.
