WT588D Programmable Sound Module - 6Pin
WTW - 16P/28P adopts WT588D voice chip as control core. Only the
peripheral gets power connection, the speaker, and the control
terminals can work. With the built-in DSP processor, and human
voice processing technology, it provides not only excellent sound
quality , but also flexible control modes, supporting MCU and key
controls. Cooperating with computer software, it can be operated to
add, delete and replace voice content freely.
WTW - 16P/28P is also provided with high reliable industrial-grade
stability as well, and can be used in various occasions.
Features :
1,Support wav audio format, 8bit/ 16Bit, mono wav files.
2,Module can be re-programmable( voice messages can be changed by
programmer).
3,Modules with 16pin(4 I/O), and 28pin(10 I/O), built-in SPI flash
memory.
4,16pins and 28 pins module with the same duration, only the 28
pins module have more I/O, so have extra control mode (parallel
interface, Matrix 3X 8).
5,Modules can be controlled by Keys, or MCU (like PIC, AVR...).
6,Support 32Mbit SPI-Flash by default and voice length can be
reached to 1,054 seconds maximum at 6KHz.
7,Support loading WAV audio formats of sampling rate 6K ~ 22KHz.
Higher sampling rate better sound quality,shorter durations.
8,Built-in 13Bit D/A convertor, 12Bit PWM output with high voice
quality.
9,Support DAC/PWM audio output modes: DAC ouput can drive higher
power speaker by adding power amplifier,PWM output can direct drive
0.5W/8ohm speaker.
10,Module can be test on the writer after programed voice.
11,Equiped with USB programmer for loading sound form PC via the PC
software online and offline.
12,Support 220 segment address bits that can be controlled, each
address can store 128 groups of voice.
13,Maximum of 500 section voice that used to edit can be loaded.
14,Support MP3 control mode, key control mode, 3*8 combined keys
control mode, parallel interface control mode, one-line serial
control mode, three-line serial control mode and three-line serial
control port extension output mode.
15,Provided with BUSY signal feedback function.
16,Chip enter sleep mode automatically without action.
17,Working voltage: 2.8VDC to 5.5VDC.
18,Standby current less than 10uA.
Parameters :
1,High-quality audio output.
2,Can be accessed 1W 8Ω speaker (with a 1W power amplifier).
3,With BUSY output.
4,Support WAV format.
5,With SPI interface, support for SPI-FLASH online download.
6,One ADC button interface, support for 5 standard MP3function
buttons.
7,With a special function keys, each time to achieve ,will play the
next sound, and single cycle the current track.
8,Support for RS232 communication, via the serial port control.
9,Long time stability, strong anti-interference ability.
10,Flexibility to support a variety of voice development program.
Usage :
Support MP3 control mode, key control mode, 3*8 combined keys
control mode, parallel interface control mode, one-line serial
control mode, three-line serial control mode and three-line serial
control port extension output mode.
Button control mode is flexible to trigger and free to set any
button to re-trigger.
There are 15 trigger ways :
Including trigger impulse repetition,trigger pluse without
repetition,invalidation keys,no cycle Level,recycled
level,non-maintained cycle level,non-cycle for the last
one,non-cycle for the next one,cycle for the last one,cycle for the
next one,volume +,volume -,play/pause,stop,play/stop, etc .
One-wire serial control mode and three-wire serial control mode,
not only can control voice play, stop, loop play and volume size by
the MCU, but also can direct triggering any voice in address bit
from 0 to 219.
Application :
Widely range of applications. Almost related to all the voice
places, such as stop devices, annunciators , reminder, alarm clock,
learning machine, intelligent home appliances, therapeutic
equipment, electronic toys, telecommunications, reversing radar and
a variety of automatic control devices, etc.
Technology meet up to the requirements of industries application :
Toys,alarm system,Walkie-talkie,therapeutic equipment,games,widely
use in museum,pictures and so on.
