General Description
The APR6008 offers non-volatile storage of voice and/or data
in advanced Multi-Level Flash memory. Up to 8 minutes of
audio recording and playback can be accommodated. A max-
imum of 30K bits of digital data can be stored.
APR6008
devices can be cascaded for longer duration recording or
greater digital storage. Device control is accomplished
through an industry standard SPI interface that allows a
microcontroller to manage message recording and playback.
This flexible arrangement allows for the widest variety of
messaging options. The
APR6008
is ideal for use in cellular
and cordless phones, telephone answering devices, personal
digital assistants, personal voice recorders, and voice pag-
ers.
achieves this high level of storage capabi-
lity
by using a proprietary analog multi-level storage te chno -
l
logy
i mplemented in an advanced non-volatile Flash memory
process. Each memory cell can typically store 256 voltage
levels. This allows the
APR6008
voice to reproduce audio
signals in their natural form, eliminating the need for enco-
ding
and compression which can introduce distortion.
