General Description
The
APR9600
devi ce offers true single-chip voice recording,
non-volatile storage, and playback capability for 40 to 60 sec-
onds. The device supports both random and sequential
access of multiple messages. Sample rates are user-select-
si
able, allowing designers to customize their design for unique
quality and storage time needs. Integrated output amplifier,
microphone amplifier, and AGC circuits greatly mplify sys-

bility by using its proprietary analog/multilevel storage tech-
nology implemented in an advanced Flash non-volatile
memory process, where each memory cell can store 256 volt-
age 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.
