ISD4004-10MSIR

The ISD4004-10MSIR is an IC component that belongs to the ISD400x series of chipsets developed by Nuvoton Technology. These chipsets are widely used in various audio recording and playback applications. The ISD4004-10MSIR, in particular, is a single-chip voice playback and record system with a maximum duration of 4 minutes. Some key features of the ISD4004-10MSIR include: 1. Non-Volatile Memory: The chip incorporates non-volatile memory technology, which ensures that the recorded voice messages are retained even when the power supply is disconnected. This feature eliminates the need for an external storage device, making it highly convenient and reliable. 2. Adjustable Sampling Rates: The ISD4004-10MSIR supports adjustable sampling rates ranging from 4 kHz to 8 kHz. This allows users to optimize the audio quality and duration based on their specific application requirements. 3. Flexible Message Length: With a maximum duration of 4 minutes, the ISD4004-10MSIR offers flexibility in creating voice messages of varying lengths. It supports a wide range of message lengths, making it suitable for applications where longer audio recordings are needed. 4. Single-Chip Solution: The chipset integrates the entire voice recording and playback system into a single IC component. This simplifies the design and reduces the overall space requirements, making it ideal for compact devices where size is a critical factor
