MX93521
ALL DIGITAL VOICE RECORDER MACHINE BASED ON THE MX93521 VOCODER CHIP
1. 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 microprocessor inter face. * Codec Interface circuit (support both TP3054 and MX93000) * Host controllable LCD Module Interface * Host writable message header (4 bytes) for identifica -tion or index purpose * Powerful Editing Function * Varieties of operating function including Rewind, Fast Forward, Repeat and message editing etc. * Voice activated recording * Use Flash memory to store user data (data bank) * Upload/Download speech message data from/to HOST * VOCODER mode (VOice COmpressor/ DEcompressoR) * Direct CODEC Play Mode (Play PCM/u-Law data re ceived from HOST) * Play Voice Prompt from ROM/FLASH memory * DTMF tone genarator
2.GENERAL 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 compression/decompression data pump. The functions supported by MX93521 are listed as followed.

HOST Write Timing (Parallel Mode)
HOST should cycle PHWRB\ after writing data to PHDB0-7. MX93521 will read data from PHDB0-7 on the falling edge of SCLK (rising edge of PHWRB\). Rxcmd will be toggled if command byte has been processed by MX93521 The PHWRB\ signal will cause MX93521 to latch data from bus PHDB0-7 to MX93521 internal register. The invertted signal of PHWRB\ will trigger MX93521 INT1\ to read and process the received data byte from internal register. Due to the interrupt contention, there might be an up to 50 us delay between the rising edge of PHWRB\ and INT1\ actually being served. To keep from command overrun, HOST should check if RxCmd toggled or wait 50 usec before sending next command byte to MX93521.

HOST Read Timing (Parallel Mode)
When MX93521 write data to PHDB0-7, PACKB\ will become low. HOST needs to poll the status of PACKB\ continuously. When HOST detect low state on PACKB\, HOST should read out data from PHDB0-7. After HOST read the data from PHDB0-7, PACKB\ will be reset to high. The maxima delay between MX93521 write data to PHDB0-7 and PACKB\ become low is 10 ns. The maxima delay between rising edge of PHRDB\ and PACKB\ become high is also 10 ns.

HOST Write Timing (Serial Mode)
RxCmd become low when start bit is received from HOST and toggle state when MX93521 received each following data bit or stop bit from HOST. Thus, instead of waiting for a fixed period of time (50us) to send a command bit, HOST could send the following command bit as soon as RxCmd toggled from previous state. The delay between the falling edge of SCLK and the RxCmd togglling time is range from 1 us to 50 us

The command 41H/10H erase all data in good blocks. After block erase, the flash management data will be written back to the flash memory. If HOST use flash memory as speech data memory and data bank memory. The command 41H/10H will erase both of the memory. To erase only speech memory, use command 19H. To erase data bank memory, use command 0CAH. The commands to control data bank memory are described from command 0B0H to command 0D6H Prior Samsung ship their flash memory to customer, they will test the parts and randomly write data 00H to those bad blocks. During the first power on, MX93521 will scan flash memory and create a good/bad table accordingly. After that, MX93521 will search the good/bad table during power on initialization. Unless good/bad table is missing, MX93521 will not do flash memory initialization again.

MX93521
We call command 41H/11H is hard erase flash memory. Because this command will erase all data in both good and bad blocks. It is possible to erase the data in those bad blocks and turn the bad blocks into good block. In this case, the original bad blocks could be unstable during normal operation. So, we are not recommend to use this command unless it is necessary. After send command 41H/11H, HOST should issue a hardware reset by toggling RST\.

Command 41H/80H & 41H/81H are only valid after recording in VOCODER mode.
HOST could send PCM or u-law format data to CODEC directly. In this mode, MX93521 send PCM/u-Law data received from HOST to CODEC (MX93000 or TP3054). MX93521 could store up to 512 samples data internally. If inetrnal buffer is empty, MX93521 will disable this mode automatically and send CMD 10H to HOST. At the beginning of Direct CODEC Access mode, MX93512 will not send data to CODEC until MX93521 received 384 samples from HOST. Old data format is the data format used in MX93510 and MX93521 V3. New data format is used in MX93521 V4 and V5. New format supports silence compression. It is always set to use new data format in MX93521 V4. MX93521 V5 will reset to use new data format after power on, RECORD or PLAY. So, if HOST want to RECORD or PLAY message using old data format, HOST needs to send command 41H/0CH every time before sending RECORD or PLAY command to MX93521.

If this is the case, HOST should re-send this command later. HOST must feed MX93521 at least 12 bytes data per 20 mini-second. When HOST send command 30H, MX93521 will not start to play until received first 60 bytes data. The procedure to do PLAY function in VOCODER mode: STEP1: Turn on VOCODER mode (send command 41H/01H) STEP2: Turn on SPKR STEP3: Set PLAY mode (Send command 30H) STEP4: Send Compressed Voice data to MX93521 (Send command 6?H+BYTE+BYTE+..) STEP5: If received ACK0, goto STEP4 to send next 6AH/6CH/6EH command If received ERR5, wait 20-180 ms, then go back to STEP4 to re-send previous command If HOST want to stop PLAY function or HOST reach the end of message, then goto STEP6 If received 10H, goto STEP7 (HOST did not send data to MX93521 fast enough) STEP6: Wait until MX93521 play out data in PLAY BUFFER (receiveing command 10H from MX93521) STEP7: Turn off SPKR STEP8: Turn off VOCODER mode (send command 41H/01H).

When MX93521 received command 81H, MX93521 will periodically send command 42H (Section 6.4) to HOST. HOST could display the RECORD/PLAY counter on LCD accordingly. This function will be disabled by MX93521 when RECORD/PLAY stop. COMMAND 88H DR-V4 FUNCTION: Download Message RETURN: ACK1, FORMAT DB7 1 DB6 0 DB5 0 (VOCODER mode, FORMAT=81H if message is recorded with new format) (VOCODER mode, FORMAT=80H if message is recorded with old format) DB4 DB3 DB2 DB1 DB0 0 1 0 0 0
Once MX93521 received this command, MX93521 will start to send compressed voice data to HOST by using command 32H or 36H. When reach the end of message, MX93521 will send out command 30H. We recommend HOST do checksum calculation during downloading. After download completed, use command 41H/81H to get the checksum from MX93521 and compare if the checksum is match. The Checksum is calculated by EXCLUSIVE OR all speech data in word format.

Each block in flash memory is 4K byte. The first 16 bytes are reserved for MX93521 as data link data, HOST could read but could not write data to it. So, the host usable data are from address 10H-0FFFH.
