APR 9301 is a single chip Voice recorder and Playback device for 20 to 30 seconds voice recording and play back. It is an ideal IC for automatic answering machine, door phones etc.
This IC has data storage capacity and requires no software and
microcontroller. It provides high quality voice recording and play back up to 30 seconds.
The IC requires minimum components to create a voice recorder. The IC has non volatile flash memory technology with 100K recording cycles and 100 year message retention capacity.
The IC utilizes the Invox proprietary analog / multi level flash non volatile memory cells that can store more than 256 voltage levels. It requires a single 5 volt supply and operates in 25 mA current.
The
LED glows when the IC records the voice obtained through the Mic. A single voice message up to 20 seconds can be recorded. The IC remains in the recorded mode as long as the RecL pin 27 is grounded. Recoding will be terminated with the last memory when 20 seconds is over. The Speaker driver will automatically mutes in the recording mode.
