ISD17180SYIR

Overview

The ISD17180SYIR is a voice recording and playback integrated circuit from Nuvoton Technology Corporation, part of the ChipCorder series. It supports multiple messages with a total duration ranging from 120 to 360 seconds. The device features an internal oscillator and operates on a supply voltage between 2.4 V and 5.5 V. It accepts analog single-ended microphone input and provides analog single-ended PWM speaker output. Sampling frequencies range from 4 kHz to 12 kHz. The component utilizes SPI and button interfaces for control. It is housed in a 28-SOIC package (0.295 inch width) and is designed for surface mount installation. The operating temperature range extends from -40°C to 85°C.

Feature Summary

• Integrated automatic gain control and volume control capabilities
• Supports multiple message storage with variable duration options
• Includes internal oscillator eliminating external crystal requirements

Applications

• Voice messaging systems
• Announcement modules
• Interactive voice response units

Procurement Notes

Verify component status as the ISD17180SYI variant is listed as obsolete with an End-of-Life date of March 25, 2024. Confirm availability through authorized distributors or check for manufacturer-recommended substitutes such as the I2361YYI or I3800FYI if current production stock is required for new designs.

Selection Notes

Select this component when a dedicated voice recording solution with SPI interface is needed. Ensure the application requires a 28-SOIC package and operates within the specified 2.4 V to 5.5 V voltage range. Verify that the required recording time fits within the 120 to 360 second capacity and that the PWM speaker output meets audio drive requirements.

Part Context

This IC belongs to the Nuvoton ChipCorder series, which focuses on standalone voice recording and playback functions without requiring a microcontroller. The ISD17180SYIR represents a specific pinout and tape-and-reel packaging variant within this family, designed for automated assembly processes.

Replacement Considerations

Manufacturer recommended substitutes include I2361YYI and I3800FYI. Verify pin compatibility and feature parity before substitution.
