ISD4003-06MSI

Overview

The ISD4003-06MSI is a single-chip voice record and playback device from the ISD4003 series, manufactured by Nuvoton Technology Corporation. It features a 28-SOIC package and supports multiple messages via an SPI interface. The device operates on a 2.7 V to 3.3 V supply with a typical standby current of 1 µA. Key electrical parameters include a sampling frequency of 5.3 kHz, a filter pass band of 2.3 kHz, and a recording duration of 6 minutes. It utilizes high-density multilevel Flash memory for non-volatile storage.

Feature Summary

• Single-chip solution integrating analog transceivers, filters, audio amplifier, and Flash memory.
• AutoMute feature provides background noise attenuation during silence periods.
• Fully addressable architecture allows handling of multiple distinct messages.
• Non-volatile message storage retains data without power consumption.

Applications

• Cellular phones and portable communication devices
• Microcontroller-based messaging systems
• Voice prompts in consumer electronics

Procurement Notes

Verify the specific suffix MSI against official datasheets to confirm package type and temperature range. Confirm end-of-life status and availability through authorized distributors. Check for recommended replacement parts if the component is discontinued. Ensure RoHS compliance matches project requirements.

Selection Notes

Select this model for applications requiring approximately 6 minutes of voice storage at 5.3 kHz sampling rate. Ensure the system voltage falls within the 2.7 V to 3.3 V range. Verify that the microcontroller supports the required SPI protocol. Consider the 28-SOIC package dimensions for PCB layout constraints.

Part Context

The ISD4003 series includes variants with 4, 5, 6, and 8-minute durations. The ISD4003-06MSI specifically offers 6 minutes of recording time. Other series members like ISD4003-04M or ISD4003-08M provide different trade-offs between sample rate and duration. All share similar interface and functional characteristics.

Replacement Considerations

Check for manufacturer-recommended substitutes such as other ISD4003 variants with compatible pinouts. Verify if updated packages or temperature grades are available. Ensure any replacement maintains the same SPI interface and voltage specifications.

FAQ

What is the maximum input signal level for optimal quality?

In single-ended mode, the maximum input signal is 32 mVp-p. In differential mode, it is 16 mVp-p.

How is the AutoMute feature configured?

Connect a 1 µF capacitor to ground on the AM CAP pin. To disable, connect AM CAP directly to VCCA.

What is the interrupt behavior upon End of Message?

The INT pin goes LOW when an EOM or Overflow is detected. It clears automatically on the next SPI cycle initiation.
