ISD17180SYI

Overview

The ISD17180SYI is a voice record and playback integrated circuit from the Nuvoton ChipCorder series, housed in a 28-SOIC package. It supports message durations ranging from 120 to 360 seconds with an internal oscillator. The device operates on a supply voltage of 2.4 V to 5.5 V and functions within a temperature range of -40°C to 85°C. Sampling frequencies are adjustable between 4 kHz and 12 kHz. Control interfaces include push-button inputs and SPI communication. Key features encompass automatic gain control, volume control, and non-volatile storage using Multi-Level Storage technology.

Feature Summary

• Integrated multi-level storage for non-volatile message retention without external memory
• Automatic gain control and microphone preamplifier for optimized audio input handling
• Built-in pulse width modulation class D speaker driver for direct audio output
• Flexible message management system supporting both standalone button and microcontroller SPI modes

Applications

• Automated voice prompts in industrial equipment
• Interactive voice response systems for consumer electronics
• Security alarm announcements and notification modules
• Educational toys and interactive learning devices

Procurement Notes

Verify component status as the ISD17180SYI is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or check for recommended replacement parts such as the I2361YYI or I3800FYI. Ensure that any substitute components meet the required pinout compatibility and electrical specifications for your specific design implementation.

Selection Notes

Select this component when fixed message durations between 120 and 360 seconds are sufficient for the application. Consider the internal oscillator if external timing components must be minimized. Evaluate the SPI interface requirement against simpler push-button control needs. Verify that the 28-SOIC package fits the board space constraints and that the operating voltage range aligns with the system power supply.

Part Context

This part belongs to the Nuvoton ISD1700 ChipCorder series, which provides fully integrated single-chip solutions for voice recording and playback. The series offers various duration options and sampling rates, allowing designers to balance audio quality against recording time. These devices utilize proprietary multi-level storage technology to eliminate the need for external flash memory, simplifying the bill of materials.

Replacement Considerations

The I2361YYI and I3800FYI are listed as manufacturer-recommended alternatives. Verify pin compatibility and functional equivalence before substitution. Check datasheets for differences in message duration ranges, package types, and interface capabilities to ensure seamless integration into existing designs.
