APR6008

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 maximum 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 pagers. APLUS achieves this high level of storage capability by using a proprietary analog multi-level storage technology implemented in an advanced non-volatile Flash memory process. Each memory cell can typically store 256 voltage levels. This allows the APR6008 device to reproduce audio signals in their natural form,eliminating the need for encoding and compression,which can introduce distortion.
