ISD5008EY

Overview

The ISD5008EY is a single-chip voice record and playback device manufactured by Nuvoton Technology Corporation. It supports recording durations of 4 to 8 minutes using internal flash memory. The component operates on a single 3V power supply and is housed in a 28-pin SOIC package. Designed for speech synthesizer applications, it integrates necessary circuitry for direct microphone input and speaker output without requiring external digital signal processing components.

Feature Summary

• Integrated flash storage eliminates the need for external memory chips
• Direct analog interface for microphone input and speaker output
• Single voltage supply operation simplifies power design

Applications

• Consumer electronic voice prompts
• Speech synthesis modules
• Automated announcement systems

Procurement Notes

Verify the specific suffix 'EY' against the official Nuvoton datasheet to confirm package type and temperature range specifications. Ensure compatibility with existing 3V power rails and SOIC footprint requirements before integration into the final hardware design.

Selection Notes

Select this model when fixed-duration voice recording between 4 and 8 minutes is required. It is suitable for applications prioritizing low component count over programmable microcontroller flexibility. Verify that the 28-SOIC package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the ISD5000 series of single-chip voice recorders. These devices are designed to replace complex digital audio solutions with simpler analog-digital hybrid circuits. The series offers various duration options depending on the specific model suffix.

Replacement Considerations

Check Nuvoton's ISD5000 series documentation for alternative models with different recording times or package types. Ensure any substitute maintains the same 3V operating voltage and 28-SOIC pinout compatibility.
