ISD4003-06MP

Overview

The ISD4003-06MP is a single-chip voice record and playback device from the ISD4003 ChipCorder series, manufactured 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 2.7 V to 3.3 V supply and features an SPI interface for control. It utilizes high-density multilevel Flash memory for non-volatile storage, supporting 100K record cycles and 100-year retention. The component is housed in a 28-SOIC package.

Feature Summary

• Direct analog storage into non-volatile Flash memory eliminates the need for digitization or compression algorithms.
• AutoMute feature attenuates background noise during silence periods without requiring external processing.
• Fully addressable multiple-message capability allows independent control of distinct audio segments via SPI commands.

Applications

• Portable cellular phone messaging systems
• Microcontroller-based voice annotation modules
• Industrial equipment status reporting

Procurement Notes

Verify the specific suffix 'MP' against official datasheets to confirm package type and temperature range, as variations exist within the ISD4003 family. Confirm availability status as legacy components may have limited stock or end-of-life notifications. Ensure the required sampling rate of 5.3 kHz aligns with system design constraints before ordering.

Selection Notes

Select this model when a 6-minute duration is required with a 5.3 kHz sampling rate. Compare against ISD4003-04M (8 kHz) or ISD4003-08M (4 kHz) if different audio quality or duration trade-offs are acceptable. Verify that the 28-SOIC package fits the PCB layout and that the commercial temperature range meets environmental requirements.

Part Context

The ISD4003-06MP belongs to the ISD4003 series, which offers 4, 5, 6, and 8-minute durations. These devices share a common architecture based on Winbond's multilevel Flash technology. The series is designed for low-power, single-supply applications where direct analog storage provides superior voice quality compared to compressed digital solutions.

Replacement Considerations

ISD4003-06MSY is a pin-compatible alternative in the same series with identical electrical specifications but potentially different packaging or temperature ratings. Verify mechanical dimensions and thermal characteristics before substitution.
