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 maximum of 30K bits of digital data can be stored. devices can be cascaded for longer duration recording or greater digital storage. APR6008 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.
