ISD5008SIR

Overview

The ISD5008SIR is a single-chip voice record and playback device from Nuvoton Technology Corporation, utilizing patented multilevel storage technology for direct analog signal retention in nonvolatile memory. It supports variable durations of 4 to 8 minutes by adjusting the sampling rate between 4.0 kHz and 8.0 kHz. The device operates on a single +3V supply with typical standby current of 1 µA. Key integrated features include automatic gain control (AGC), summing amplifiers, volume control, and a speaker driver capable of delivering 23 mW into an 8 Ω load. Control is managed via a standard SPI interface.

Feature Summary

• Integrated multilevel nonvolatile storage array enabling zero-power message retention without compression algorithms.
• Built-in audio processing chain including AGC, summing amplifiers, and configurable input/output gain stages.
• Flexible microcontroller interface supporting SPI protocol for addressable message management and configuration.

Applications

• Digital cellular phone call recording and screening
• Automotive communication systems and car kits
• GPS and navigation system voice prompts

Procurement Notes

Verify the specific suffix 'SIR' against the manufacturer's official datasheet to confirm package type and temperature range specifications. Ensure the ordering information matches the exact revision required for your design implementation.

Selection Notes

Select this component when a fully integrated solution for short-duration voice messaging is required. Consider the available sample rates to balance audio fidelity against total recording time needs within the 4 to 8 minute window.

Part Context

This part belongs to the ISD5008 ChipCorder series, designed for seamless integration into portable and automotive electronics. It replaces discrete audio components by consolidating recording, playback, and interface logic onto a single silicon die.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing firmware if considering alternative voice recording ICs from other manufacturers.
