ISD17120SYIR

Overview

The ISD1760SYIR is a multi-message single-chip voice record and playback device from the Nuvoton ISD1700 ChipCorder series. It features user-selectable message durations ranging from 20 to 480 seconds, with an 80-second duration at 12 kHz sampling frequency. The operating voltage spans 2.4 V to 5.5 V, supporting both standalone push-button and SPI microcontroller modes. Key components include a differential microphone input with Automatic Gain Control (AGC), an auxiliary analog input, and dual output channels comprising a PWM Class D speaker driver and a configurable analog output.

Feature Summary

• Integrated message management system enabling self-managed address locations for multiple messages in standalone mode.
• Dual operating modes allowing either simple push-button control or full microcontroller management via SPI interface.
• On-chip Flash memory storage using Multi-Level Storage technology for zero-power retention without digital compression.
• Flexible audio path configuration through Analog Path Configuration register for input/output mixing and feed-through.

Applications

• Electronic systems requiring high-quality voice prompts and announcements
• Battery-powered devices utilizing low standby current and automatic power-down
• Industrial equipment needing robust voice recording and playback capabilities

Procurement Notes

Verify the specific suffix 'SYIR' against official ordering information to confirm package type and temperature grade. Ensure compatibility with required sampling frequencies by selecting appropriate external oscillator resistors. Confirm that the application environment falls within the specified commercial or industrial temperature ranges defined in the datasheet.

Selection Notes

Select this component when a single-chip solution for multi-message voice applications is required. Consider the ISD1760 variant specifically for its 80-second maximum duration at 12 kHz sampling rate. Evaluate the need for SPI control versus standalone operation to determine interface complexity. Ensure the system design accommodates the 2.4 V to 5.5 V supply voltage range.

Part Context

The ISD1760SYIR belongs to the Nuvoton ISD1700 ChipCorder series, which provides fully integrated voice recording and playback functionality. This series utilizes patented Multi-Level Storage technology to store audio data directly in solid-state memory. The family includes variants with different message durations, catering to various application requirements while maintaining consistent core features and interfaces.

Replacement Considerations

Direct replacements within the ISD1700 series include ISD1730, ISD17120, and ISD17240, depending on required message duration. Verify pinout compatibility and software command sets if migrating between different duration variants within the same series.
