MX93521UC - ALL DIGITAL VOICE RECORDER MACHINE BASED ON THE MX93521 VOCODER CHIP

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.

Features

  • Excellent sound quality by adopting 4800bps CELP speech compression alogorithm.
  • Silent Compression algorithm to further compress si lence between speech.
  • Flash Memory Management alogorithm to manage down-graded Flash Memory to store compressed speech data. With silent compression, one 4Mbit flash memory could store up to 18 minutes speech.
  • Support 4/8/16/32 Mbit Samsung Flash Memory or its compatible parts.
  • Support both parallel and serial micropr.
