ISD4003-06MPY

Overview

The ISD4003-06MPY is a single-chip voice record/playback device from the ISD4003 ChipCorder series by Nuvoton Technology Corporation. It provides 6 minutes of recording duration at a sampling frequency of 5.3 kHz, with a typical filter pass band of 2.3 kHz. The device operates on a single 3V supply (2.7V to 3.3V) and features low power consumption, including a standby current of 1 µA. It utilizes multilevel Flash memory for non-volatile storage, supporting 100-year retention and 100K record cycles. Control is managed via an SPI or Microwire interface, and it includes an AutoMute feature for noise attenuation.

Feature Summary

• Direct analog storage technology preserves natural voice quality without digitization or compression artifacts.
• AutoMute function minimizes background noise during playback silence periods.
• Fully addressable memory architecture allows handling of multiple messages via SPI control.
• Zero-power message storage ensures data retention without continuous power supply.

Applications

• Cellular phones and portable electronic devices requiring voice messaging
• Industrial human-machine interfaces (HMI) for voice prompts
• Automotive lane departure warning systems

Procurement Notes

Verify the specific suffix 'MPY' against official ordering information to confirm package type and temperature grade. Confirm availability status as product lines may undergo lifecycle changes. Ensure compatibility with system voltage levels and SPI protocol requirements before integration.

Selection Notes

Select this model for applications requiring approximately 6 minutes of audio time. Choose based on required sampling rate trade-offs between audio fidelity and duration. Verify industrial temperature range requirements (-40°C to +85°C) if operating in harsh environments. Ensure microcontroller supports SPI or Microwire interfaces for control.

Part Context

The ISD4003-06MPY belongs to the ISD4003 series, which offers durations ranging from 4 to 8 minutes. This series is designed for microprocessor-based systems, providing a complete solution with integrated oscillators, filters, and amplifiers. It replaces older discrete recording solutions by integrating high-density multilevel Flash memory on a single CMOS chip.

Replacement Considerations

ISD4003-04MPY: Shorter duration (4 min), higher sample rate (8.0 kHz). ISD4003-05MPY: Shorter duration (5 min), higher sample rate (6.4 kHz). ISD4003-08MPY: Longer duration (8 min), lower sample rate (4.0 kHz). All share identical pinouts and control interfaces.
