ISD1612BSYI

Overview

The ISD1612BSYI is a single-message, single-chip voice record and playback device manufactured by Nuvoton Technology Corporation. It supports recording durations ranging from 6.6 to 40 seconds, with the specific 'ISD1612' designation typically indicating a 12-second capacity variant. The component integrates voice alert options and operates within standard industrial voltage ranges. It utilizes a PDSO16 package, providing a compact solution for embedded audio applications requiring simple one-time message storage and playback without external microcontrollers.

Feature Summary

• Single-chip integration of voice recording and playback functions
• Supports variable duration recording up to 40 seconds
• Includes built-in voice alert capabilities
• Compact surface-mount packaging for space-constrained designs

Applications

• Voice-enabled consumer electronics
• Industrial control panel announcements
• Security system alerts
• Educational learning aids

Procurement Notes

Verify the exact suffix configuration against the manufacturer's current datasheet to confirm pinout compatibility and recording duration specifications. Ensure the ordering part number matches the required package type and temperature grade. Cross-reference with official distributor catalogs to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a dedicated, low-pin-count solution for single-message playback is required. Compare total system cost against MCU-based alternatives if multi-message or complex audio processing is needed. Verify power supply requirements and interface compatibility with the target application's logic levels prior to integration.

Part Context

This part belongs to the ISD16xx series of voice record/playback chips. Variants in this family differ primarily in recording time and package options. The ISD1612BSYI represents a specific configuration within this line, offering a balance between recording capacity and physical footprint for general-purpose audio signaling tasks.

Replacement Considerations

Check for direct substitutes such as ISD1612BS or other suffixes from Winbond or Nuvoton that share identical pinouts and functionality. Ensure any replacement maintains the same recording duration and package dimensions to fit existing PCB layouts without modification.
