ISD17180SY

Overview

The ISD17180SYI is a voice recording and playback integrated circuit from the ChipCorder series by Nuvoton Technology Corporation. It supports multiple messages with a total duration of 120 to 360 seconds. The device features an internal oscillator and accepts analog single-ended input signals from microphones. It interfaces via buttons or SPI and provides analog single-ended output along with PWM speaker output. Operating on a supply voltage of 2.4 V to 5.5 V, it samples at frequencies between 4 kHz and 12 kHz. The component is housed in a 28-SOIC package and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrated automatic gain control and volume control for optimized audio performance.
• Supports multiple message storage with flexible recording durations.
• Includes internal oscillator eliminating external clock components.

Applications

• Voice messaging systems
• Automated announcements
• Interactive voice response units
