ISD1820PY Datasheet – Voice Record IC – ISD

Part Number : ISD1820PY, 1820PY

Function : Voice Record IC

Package : DIP 14 Pin Type

Manufactures : ISD


ISD1820PY Voice Record Module



The ISD1820 voice module board may be a good answer for an additional single sound effect to a project. These boards can record a single audio sample of up to 10 seconds using a built-in microphone and will play back the sample on demand with good fidelity. There are two playback modes. The first is edge triggered; a positive pulse to the Playback-E pin triggers the module to play the entire message once. The second method, level triggered, will play the recording while it is high, and stop playing when it is low. This module use is very easy which you could direct control by push button on board or by microcontroller such as arduino.
