Overview
The ISD4004-16MS is a single-chip voice record/playback solution from the Nuvoton ISD4004 ChipCorder series, designed for 16-minute messaging applications. It operates on a single 3V supply and features an on-chip oscillator, anti-aliasing filter, smoothing filter, AutoMute feature, audio amplifier, and high-density multilevel Flash memory array. The device supports microcontroller-based control via SPI or Microwire interfaces. Key electrical parameters include a typical operating current of 25 mA during recording and 1 µA in standby. It 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
- Microcontroller interface via SPI or Microwire Serial Interface
Applications
- Cellular phones
- Portable products requiring messaging functionality
- Voice recording devices
- Audio playback systems
Procurement Notes
Verify the specific suffix 'MS' against the official ordering information table to confirm package type and temperature range. Ensure compatibility with the required sampling rate and duration specifications for your application design.
Selection Notes
Select based on required recording duration, as the ISD4004 series offers options ranging from 8 to 16 minutes. Consider the operating temperature range (Commercial vs. Industrial) and power consumption requirements. Verify interface compatibility with the host microcontroller's SPI or Microwire settings.
Part Context
The ISD4004-16MS belongs to the Nuvoton ISD4004 ChipCorder series, which provides high-quality, 3-volt, single-chip record/playback solutions. This series utilizes patented multilevel storage technology to store voice and audio signals directly onto memory arrays without digitization or compression.
Replacement Considerations
Check for other variants within the ISD4004 series (e.g., ISD4004-08M, ISD4004-10M, ISD4004-12M) if different recording durations are acceptable. Verify pinout and interface compatibility before substituting.
