ISD4003-06MSYI

Overview

The ISD4003-06MSYI 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 and supports industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Direct analog storage technology preserves natural voice quality without digitization or compression algorithms.
• Integrated AutoMute feature attenuates background noise during silence periods to improve audio clarity.
• Fully addressable memory architecture allows for multiple message handling via SPI or Microwire interfaces.
• On-chip oscillator and filters eliminate the need for external clocking components in standard applications.

Applications

• Portable cellular phones and mobile communication devices
• Industrial automation systems requiring voice prompts
• Security and alarm systems with spoken status messages

Procurement Notes

Verify the specific suffix 'I' confirms industrial temperature range (-40°C to +85°C) versus commercial variants. Confirm package type matches design requirements, as SOIC and PDIP options exist within the series. Check current availability status as legacy components may have limited stock or end-of-life implications.

Selection Notes

Select this model when 6 minutes of message duration is required. Choose over ISD4003-04M or ISD4003-05M if longer storage is needed, or over ISD4003-08M if higher sampling rates are not critical. Ensure the system voltage aligns with the 2.7V to 3.3V specification. Verify that the microcontroller supports the required SPI protocol for command execution.

Part Context

The ISD4003-06MSYI belongs to the ISD4003 series, which offers 4, 5, 6, and 8-minute duration options. All members share the same core architecture, including the multilevel Flash memory array and SPI interface. The primary differences lie in sampling frequency, filter bandwidth, and total recording time, allowing designers to balance audio quality against storage capacity.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific variant. Designers should evaluate other ISD4003 series models (e.g., ISD4003-05MSYI or ISD4003-08MSYI) based on duration and sampling rate requirements, ensuring pin compatibility remains consistent across the SOIC package family.
