Working Principles

ISD5008EIR operates based on the principle of digital audio recording and playback. It utilizes an integrated memory to store audio data, which can be accessed and played back as per the user's requirements. The chip interfaces with a microcontroller through the SPI interface, enabling control and data transfer. Audio signals are captured by the connected microphone and processed internally before being stored in the memory. During playback, the stored audio data is retrieved and sent to the connected speaker for output.
