ISD4004-10MPY

Overview

The ISD4004-10MPY is a single-chip voice record/playback solution from Nuvoton’s ISD4004 ChipCorder series, designed for 8- to 16-minute messaging applications. It operates on a single 3-volt supply and features an internal oscillator, anti-aliasing filter, smoothing filter, AutoMute feature, audio amplifier, and high-density multilevel Flash memory array. The device supports direct analog storage of voice and audio signals without digitization or compression, ensuring high-quality reproduction. It communicates via SPI or Microwire serial interface and offers non-volatile message storage with 100-year retention and 100K record cycles.

Feature Summary

• Single-chip voice record/playback solution with direct analog storage
• AutoMute feature for background noise attenuation during playback
• Non-volatile message storage with long-term retention capabilities
• SPI or Microwire serial interface for microcontroller integration

Applications

• Cellular phones
• Portable products requiring messaging functionality
• Voice recording devices
• Audio playback systems

Procurement Notes

Verify the specific suffix '10MPY' against official ordering information to confirm package type (PDIP/SOIC) and temperature grade (Commercial/Industrial). Ensure compatibility with system voltage requirements (2.7V to 3.3V) and interface protocols (SPI/Microwire). Check for lead-free packaging status as specified in the datasheet.

Selection Notes

Select based on required recording duration (10 minutes for this model) and sampling frequency (6.4 kHz). Consider power consumption needs, noting typical operating currents of 15 mA for playback and 25 mA for record. Evaluate interface requirements, ensuring the host microcontroller supports SPI or Microwire communication. Assess environmental conditions to choose between commercial or industrial temperature ranges if applicable.

Part Context

The ISD4004 series includes variants with 8, 10, 12, and 16-minute durations. The -10M variant specifically provides 10 minutes of recording time at a 6.4 kHz sampling rate. This series is part of Nuvoton's broader portfolio of audio solutions, leveraging patented multilevel storage technology for high-density, non-volatile memory applications.

Replacement Considerations

Direct replacements within the ISD4004 series include ISD4004-08M, ISD4004-12M, and ISD4004-16M, differing primarily in recording duration and sampling rate. Verify pinout and interface compatibility when substituting. No other specific substitute part numbers are publicly confirmed in the provided documentation.
