ISD1610BSYR

Overview

The ISD1610BSYR is a voice record and playback integrated circuit from the ChipCorder series, manufactured by Nuvoton Technology Corporation. It supports single-message audio applications with a recording duration ranging from 6.6 to 20 seconds. The device operates on a power supply voltage of 2.4 V to 5.5 V and features an internal oscillator. Audio output is provided via analog single-ended or PWM signals, supporting frequencies between 4 Hz and 12 kHz. It includes automatic gain control and functions within a temperature range of -40°C to 85°C (TA).

Feature Summary

• Integrated voice recording and playback functionality for single-message applications.
• Supports pushbutton-triggered operation without external microcontroller.
• Includes automatic gain control for consistent audio levels.
• Features internal oscillator eliminating need for external clock components.

Applications

• Pushbutton-triggered voice message systems
• Single-message audio announcements
• Voice-guided user interfaces
• Simple audio alert devices

Procurement Notes

Verify component authenticity through authorized distributors as the ISD1610 series may have limited availability. Confirm package type matches design requirements, specifically the 16-SOIC variant for this model. Check for obsolescence status and lead times due to potential discontinuation of older ChipCorder generations. Ensure supply chain stability for long-term production needs.

Selection Notes

Select this component for simple, cost-effective voice messaging where microcontroller resources are constrained. Suitable for applications requiring fixed-length messages triggered by physical buttons. Consider thermal performance if operating near the upper temperature limit. Verify interface compatibility with speaker loads when choosing between analog and PWM outputs.

Part Context

Part of Nuvoton's ChipCorder family designed for standalone voice applications. Replaces earlier discrete solution designs by integrating memory, ADC, DAC, and control logic into a single package. Commonly used in consumer electronics and industrial controls requiring basic audio feedback.

Replacement Considerations

Direct substitutes include ISD1610BPIY (DIP package) and ISD1610BSY (SOIC package). Cross-reference pinouts and electrical specifications before substitution. Verify that alternative packages meet mechanical constraints of the target PCB layout.
