1. FEATURES
MX93521
APPLICATION NOTE V7
• Excellent sound quality by adopting 4.8Kbps CELP and
13Kbps speech compression alogorithm.
• Silent Compression algorithm to further compress si
lence between speech.

memory could store up to 18 minutes speech.
• Support 4/16/32/64M bit Samsung flash memory or
its compatible parts.
• Support both parallel and serial microprocessor interface.
• Codec Interface circuit (support both TP3054, MX93000
and MX93000C).
• Host controllable LCD Module Interface.
• Host writable message header (4 bytes) for identification 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 should cycle PHWRB\ after writing data to PHDB0-7.

Rxcmd will be toggled if command byte has been processed by MX93521
th
tp
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 w ait 50 usec before sending
next command byte to MX93521.

When MX93521 write data to PHDB0-7, P ACKB\ will become lo w. 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.

RxCmd become low when start bit is received from HOST and toggle state when MX93521 received each follo wing
data bit or stop bit from HOST . Thus, instead of waiting f or a fixed period of time (50us) to send a command bit, HOST
could send the following command bit as soon as RxCmd toggled from pre vious state. The dela y between the falling
edge of SCLK and the RxCmd togglling time is range from 1 us to 50 us

The command 41H/10H er ase all data in good blocks. After b lock 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
2
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, w e 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\.
3
Command 41H/80H & 41H/81H are only valid after recording in V OCODER mode.
4
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 disab le 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 .
5
Old data format is the data format used in MX93510 and MX93521 V3. Ne w data format is used in MX93521 V4 and
V5. Ne w format supports silence compression. It is alw ays set to use ne w data format in MX93521 V4. MX93521 V5
will reset to use new data format after power on, RECORD or PLA Y. So , if HOST want to RECORD or PLA Y message
using old data format, HOST needs to send command 41H/0CH every time before sending RECORD or PLAY
command to MX93521.

MX93521 equipped a 64 words PLAY BUFFER, HOST should keep feeding compressed voice data to MX93521
when doing PLA Y function. Once PLAY BUFFER have no enough data to pla y, MX93521 will stop playing and send
command 10H to HOST. When the PLAY BUFFER is full, MX93521 will response ERR5. 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 PLA Y 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 V oice 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 pla y out data in PLA Y BUFFER (receiv eing command 10H from MX93521)
STEP7: Turn off SPKR
STEP8: T urn 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/PLA Y stop.

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 Chec ksum is calculated by EXCLUSIVE OR
all speech data in word format.

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