Overview
The ISD4003-06MS is a single-chip voice record and playback device from the ISD4003 series, manufactured by Nuvoton Technology Corporation. It provides approximately 6 minutes of recording duration at a sampling frequency of 5.3 kHz. The typical filter pass band is 2.3 kHz. The device operates on a single 3-volt supply with an operating current of 15 mA during playback and 25 mA during recording. Standby current is typically 1 µA. It features a 28-pin SOIC package and utilizes SPI or Microwire serial interfaces for control.
Feature Summary
- Single-chip solution with high-quality natural voice reproduction using direct analog storage in non-volatile Flash memory.
- Integrated AutoMute feature for background noise attenuation during silence periods.
- Microcontroller-compatible SPI or Microwire interface for fully addressable multiple message handling.
- Zero-power message storage with 100-year retention and 100K record cycle endurance.
Applications
- Cellular phones
- Portable products requiring messaging capabilities
- Microprocessor or microcontroller-based systems
Procurement Notes
Verify the specific suffix 'MS' against the manufacturer's official ordering guide to confirm the package type (SOIC) and temperature range. Ensure the required recording duration aligns with the 6-minute specification of this variant rather than other durations in the series.
Selection Notes
Select this component when a fixed 6-minute recording time is required. Consider the 5.3 kHz sampling rate and 2.3 kHz filter pass band for audio quality requirements. Verify that the system can support the 3V supply voltage and SPI/Microwire interface protocols.
Part Context
The ISD4003-06MS belongs to the ISD4003 ChipCorder series, which offers 4, 5, 6, and 8-minute duration options. These devices are designed for portable applications and utilize Winbond’s multilevel Flash technology for direct analog storage without digitization or compression.
Replacement Considerations
Other variants in the ISD4003 series such as ISD4003-04M, ISD4003-05M, and ISD4003-08M share the same interface and pinout but offer different recording durations and sampling frequencies. Direct substitution requires verifying if the alternative duration meets application needs.
