Product Details

Description



Features:

·  Switchable 4.8kbps/12.8kbps speech compression/ decompression algorithm for message recording/play- back.
·  Minimum 15 or 40 minutes of recording time for one 16M bits MX29F16A FLASH based on 12.8K or 4.8K compression rate, respectively.
·  Low (4.8kbps) or High (12.8kbps) compression rate with silence management technique for voice prompt making. Voice prompt can be stored in Flash memory.
· Support total 127 messages, maximum 7 OGMs and maximum 8 personal mailboxes.
·  DTMF generation and detection with near-end echo cancellation.
·  Provide single low crystal solution (FLL).
· Built-in DSP mode and MCU mode. In DSP mode, user can mask the system code into the MX93032- M1. In MCU mode, user can control the MX93032-M1 via MCU (micro controller).
· Provide standard sample program written by 8051 assemble for customer development.
·  Full duplex speakerphone with both acoustical echo canceller (AEC) and line echo canceller (LEC)
·  Built-in CAS signal detector for monitoring the pres- ence CPE alerting signal in Calling Identity Delivery on Call Waiting.
· FSK decoder for Calling Identity Delivery on CID Type I and CID Type II
· Caller ID Type II can be turned on under speaker phone mode
· Auto detecting MCU mode and DSP mode

Description

MX93032-M1 is an engine chip on which digital an- swering machine (DAM) with full duplex speaker phone is implemented. Besides, CAS tone detection capa- bility and FSK decoder for Caller-ID service has also been implemented as well.

It provides speech processing / management mod- ules, including speech compression/decompression, silence management, telephone line signal process- ing, Macronix MX29F16A FLASH management, line echo cancellation and acoustical echo cancellation, etc.

 The MX93032-M1 has built-in DSP mode and MCU mode. In DSP mode, users do not need external mi- croprocessors and can effectively reduce the overall system cost in DAM with full-duplex speakerphone system. In MCU mode, the MX93032-M1 is controlled by an MCU (micro controller) via a 8 bit parallel or serial interface.
