Overview
The ISD4003-08MP is a single-chip voice record/playback device from the ISD4003 ChipCorder series, manufactured by Nuvoton Technology Corporation. It provides an 8-minute recording duration at a sampling frequency of 4 kHz with a filter pass band of 1.7 kHz. The device operates on a single 2.7 V to 3.3 V supply and features an internal/external oscillator. It utilizes a 28-TSOP package for surface mount installation and supports an operating temperature range of -40°C to +85°C.
Feature Summary
- Direct analog storage into non-volatile Flash memory without digitization or compression
- AutoMute feature for background noise attenuation during playback silence
- Microcontroller SPI or Microwire serial interface for address and control
Applications
- Cellular phones and portable messaging devices
- Microprocessor-based systems requiring multiple message handling
- Industrial applications within extended temperature ranges
Procurement Notes
Verify component authenticity through authorized distributors or manufacturer channels. Confirm package integrity and pin alignment against the 28-TSOP specification. Ensure environmental conditions match the industrial rating requirements before deployment in critical systems.
Selection Notes
Select this model for applications requiring up to 8 minutes of audio storage at 4 kHz sampling. Consider the ISD4003-06MP or ISD4003-05MP if shorter durations are acceptable for lower power consumption. Verify interface compatibility with the host microcontroller's SPI or Microwire protocol.
Part Context
Part of the ISD4003 ChipCorder series offering 4 to 8-minute durations. Uses multilevel Flash technology for high-density storage. Designed for low-power portable electronics. Replaces older Winbond ISD4000 series components with improved integration.
Replacement Considerations
ISD4003-06MP offers 6 minutes duration. ISD4003-05MSIR provides 5 minutes in 28-SOIC. Check pinout compatibility when substituting packages.
FAQ
How does the AutoMute feature function?
It attenuates background noise by 6 dB during periods of silence by comparing signal amplitude to an internal threshold.
What is the maximum input voltage for ANA IN+?
In single-ended mode, the maximum input is 32 mVp-p. In differential mode, it is 16 mVp-p.
Can the device be used for playback-only applications?
Yes, it supports playback-only operations controlled via the SPI port after configuration.
