ISD1612BSYR

Overview

The ISD1612BSYR 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, allowing for flexible message lengths based on sampling rates. The component integrates digital signal processing capabilities directly onto the silicon die, eliminating the need for external memory or complex interface logic. Designed for straightforward integration into embedded systems, it features a built-in amplifier output stage suitable for driving low-impedance speakers. The device operates within standard industrial temperature ranges and utilizes a compact surface-mount package to minimize board space requirements.

Feature Summary

• Integrated single-chip architecture combining flash memory, ADC, DAC, and audio amplification
• Supports variable recording time options between 6.6 and 40 seconds
• Built-in speaker driver output reduces external component count
• Simple control interface requiring minimal microcontroller interaction

Applications

• Industrial equipment status alerts and fault announcements
• Consumer product voice prompts and user instructions
• Automotive interior warning chimes and navigation cues
• Security system voice messages and access codes

Procurement Notes

Verify the specific suffix 'SYR' against official Nuvoton documentation to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with existing PCB footprints for the SOIC-16 package. Cross-reference lot dates and revision levels to match current production standards. Confirm that the selected variant meets the required recording duration specifications for the target application.

Selection Notes

Select this component when a fixed, single-message playback is sufficient without complex sequencing. Evaluate the required recording length against the available sampling rate options to ensure adequate audio quality. Consider the power supply voltage range and operating temperature limits relative to the end-use environment. Verify that the integrated amplifier output power meets the acoustic requirements of the enclosure design.

Part Context

This part belongs to the ISD1612 series of single-message voice ICs. Variants in this family typically differ by recording duration, package type, and temperature rating. The ISD1612BSYR represents a specific configuration within this lineup, optimized for volume manufacturing through reel packaging. It shares core functionality with other members of the ISD16xx series but offers distinct physical and operational characteristics defined by its suffix.

Replacement Considerations

Direct substitutes may include other ISD1612 variants with matching recording times and package styles. Verify pin-to-pin compatibility before replacing components in existing designs. Alternative manufacturers offer similar single-message voice ICs, but interface timing and electrical characteristics must be validated for equivalence.
