2 General Description :
The APR9600 device offers true single-chip voice recording,non-volatile storage, and
playback capability for 40 to 60 seconds.The device supports both random and sequential
access of multiple messages.Sample rates are user-selectable,allowing designers to
customize their design for unique quality and storage time needs.Integrated output
amplifier,microphone amplifier, and AGC circuits greatly simplify system design. the device
is ideal for use in portable voice recorders, toys, and many other consumer and industria
applications.
APLUS integrated achieves these high levels of storage capability by using its proprietary
analog/multilevel storage technology implemented in an advanced Flash non-volatile
memory process, where each memory cell can store 256 voltage levels.
This technology enables the APR9600 device to reproduce voice signals in their natural
form. It eliminates the need for encoding and compression, which often introduce distortion.
