3064 - 120 Second Message Recorder (ISD25120 ChipCorder IC)

This Message Recorder module uses a high quality 120 second non-volatile ISD25120 ChipCorder audio recording IC by Winbond and features a useful loop option that enables continuous playback of a message.

The IC has several modes of operation and we use it here as a sequential multi-message recorder (like a telephone message recorder). You can record as many messages as you want up to 120 seconds total (see Order Code 3146 for a lower cost 40 second version). You can then play them back on command and there is loop option that enables continuous playback of a message.

Recording and playback operations are controlled using the RECORD/PLAYBACK mode switch and the START/PAUSE and STOP/RESET buttons. A switch is used to select Loop or Normal playback. Loop will repeat the message indefinitely with no pause between repeats.

Board has a built-in microphone and an LEDs to indicate Recording and Playback.
