Overview
The ISD4002-120SIR is a single-chip voice record/playback device from the Nuvoton ISD4002 series, designed for portable applications. It features 120 seconds of recording duration at an 8.0 kHz sampling frequency with a typical filter passband of 3.4 kHz. The device operates on a single 3V supply (2.7V to 3.3V) and includes an on-chip oscillator, anti-aliasing filter, smoothing filter, AutoMute feature, audio amplifier, and high-density multilevel Flash memory array. It utilizes a Serial Peripheral Interface (SPI) or Microwire serial interface for microcontroller control. The component is housed in a 28-pin TSSOP package.
Feature Summary
- Direct analog storage into non-volatile Flash memory without digitization or compression
- AutoMute feature provides background noise attenuation during silence periods
- Fully addressable multiple message handling via SPI or Microwire interface
- Zero-power message storage with high retention and endurance capabilities
Applications
- Cellular phones and other portable products requiring messaging
- Microprocessor or microcontroller-based systems needing voice prompts
- Playback-only applications controlled through the SPI port
Procurement Notes
Verify the specific ordering suffix 'SIR' against manufacturer documentation to confirm package type and temperature range. Confirm RoHS compliance status as specifications may vary by production batch. Ensure the source document explicitly lists this exact part number variant before procurement.
Selection Notes
Select the ISD4002-120SIR when 120 seconds of voice storage is required at 8.0 kHz sampling rate. Choose this model over other series variants if the commercial temperature range (0°C to +70°C) meets system requirements. Verify that the 28-pin TSSOP package fits the PCB layout constraints.
Part Context
The ISD4002 series belongs to the ChipCorder family of single-chip voice record/playback devices. This series offers durations ranging from 120 to 240 seconds. The ISD4002-120SIR specifically provides the shortest duration option within the standard lineup, optimized for compact portable designs where minimal recording time suffices.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for potential obsolescence management or alternative series components.
