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-
able, allowing designers to customize their design for unique
quality and storage time needs. Integrated output amplifier,
microphone amplifier, and AGC circuits greatly
si
mplify sys-
tem design. the device is ideal for use in portable voice
recorders, toys, and many other consumer and industrial
applications.
APLUS integrated achieves these high levels of storage capa-
bility by using its proprietary analog/multilevel storage tech-
nology implem ented 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.
