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.
