General Description

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 implemented in an advanced Flash non-volatile

memory process, where each memory cell can store 256 volt-

reproduce voice signals in their natural form. It eliminates the

need for encoding and compression, which often introduce

distortion.
