Working Principle of ISD 1820 Voice Recording Module

The ISD1820 module works by recording audio signals directly from the built-in microphone and storing them in its internal analog memory. When the record button is pressed, the IC captures and stores the sound waveform.

During playback, the stored audio signal is retrieved and amplified by the onboard amplifier, allowing it to be played through a speaker or external audio circuit. The module supports both manual control through buttons and digital control via microcontroller pins.

Because the storage is non-volatile, the recorded message remains saved even when power is removed.
