Description

This document describes how to implement an all-digital voice recorder using the MX93521 chip. The MX93521 is a Digital Recorder Data Pump which is controlled by an external microprocessor to perform various recorder function.

The MX93521 is fully controlled by a HOST controller through a simple HOST interface protocol. The HOST could initiate many digital recording  functions such as record, play, repeat, search, skip, insertion, message managing and self-diagnosis. Also, HOST could set MX93521 in VOCODER mode and use MX93521 as a speech compres- sion/decompression data pump. The functions supported by MX93521 are listed as followed.
