ISD1616BSYR

Overview

The ISD1616BSYR is a voice record and playback integrated circuit from Nuvoton’s ChipCorder series. It supports single message recording with a duration of 10.6 to 30 seconds. The device features an internal microphone input and provides analog single-ended PWM speaker output. It utilizes a pushbutton interface for operation control. The component is housed in a 16-SOIC package with a width of 3.90 mm (0.154 inches). It is designed for surface mount applications and is currently active in production.

Feature Summary

• Integrated voice recording and playback functionality within a single chip
• Supports pushbutton interface for direct user interaction without complex logic
• Includes internal microphone input capability for audio capture
• Delivers analog single-ended PWM output suitable for driving speakers

Applications

• Single-message announcement systems
• Voice greeting modules
• Simple audio notification devices
• Educational voice toys

Procurement Notes

Verify the specific suffix 'SYR' matches the required tape and reel packaging configuration. Confirm that the 16-SOIC footprint aligns with the target PCB design. Ensure the application voltage requirements are compatible with the system power supply. Check for any regional distribution restrictions or authenticity certification requirements before finalizing the order.

Selection Notes

Select this component when a simple, low-cost solution for short-duration voice messages is required. It is suitable for applications where a pushbutton trigger is acceptable and no complex microcontroller interface is needed. Consider the 30-second maximum recording time limit. Evaluate the analog PWM output quality against the specific speaker impedance and acoustic requirements of the end product.

Part Context

This part belongs to Nuvoton’s ChipCorder family, which specializes in standalone voice ICs. These components are designed to replace discrete memory and audio circuits in consumer electronics. The series offers high performance-to-cost ratios by integrating flash memory, audio processing, and I/O controls into a single package, simplifying board layout and reducing component count.

Replacement Considerations
