WT588D Programmable Sound Module -28Pin

Description :

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 16Mbit or 32Mbit SPI-Flash 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.
