ISD17120SY

Overview

The ISD17120SYIR is a single-chip multi-message voice record and playback device from the Nuvoton ISD1700 ChipCorder series. It features user-selectable message durations ranging from 26 to 120 seconds, with sampling frequencies adjustable between 4 kHz and 12 kHz via an external resistor. The device operates on a supply voltage of 2.4 V to 5.5 V and includes an integrated microphone preamplifier with Automatic Gain Control (AGC), a PWM Class D speaker driver, and auxiliary analog outputs. It supports both standalone push-button operation and SPI microcontroller control modes.

Feature Summary

Integrated message management system enabling self-managed address locations for multiple messages in standalone mode.
Dual input channels supporting differential microphone inputs with AGC and single-ended auxiliary analog input.
Dual output channels providing direct drive capability for 8 Ω speakers via PWM Class D and configurable current/voltage analog outputs.
On-chip Flash memory storage using Multi-Level Storage technology for zero-power message retention without digital compression.

Applications

Electronic systems requiring simple push-button voice messaging
Battery or line-powered audio devices
Microcontroller-based voice recording applications

Procurement Notes

Verify the specific package type and temperature grade required for your application against the ordering information in the datasheet. Ensure the component matches the exact suffix specifications for lead-free packaging and industrial or commercial temperature ranges before procurement.

Selection Notes

Select this model when a maximum recording duration of approximately 120 seconds at 8 kHz is sufficient. Consider the ISD1730, ISD1760, or ISD17240 if longer or shorter durations are needed. Verify that the required sampling frequency aligns with the available external oscillator resistor values to meet quality and size constraints.

Part Context

The ISD17120SYIR belongs to the Nuvoton ISD1700 ChipCorder series, which offers high-quality, fully integrated voice recording solutions. This series utilizes patented Multi-Level Storage technology to store audio data directly in solid-state memory, ensuring superior voice reproduction compared to compressed formats.
