WT588D Programmable Sound Module 28pin

WT**8D Programmable Sound Module **8Pin

Description:

WTW - *6P/*8P adopts WT**8D 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 - *6P/*8P 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/ *6Bit, mono wav files.

2, Module can be re-programmable( voice messages can be changed by programmer).

3, Modules with *6pin(4 I/O), and *8pin(*0 I/O), built-in SPI flash memory.

4, *6pins and *8 pins module with the same duration, only the *8 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 *6Mbit or *2Mbit SPI-Flash and voice length can be reached to 1, **4 seconds maximum at 6kHz.

7, Support loading WAV audio formats of sampling rate 6K ~ *2kHz. Higher sampling rate better sound quality, shorter durations.

8, Built-in *3Bit D/A convertor, *2Bit 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.

*0, Module can be test on the writer after programed voice.

*1, Equiped with USB programmer for loading sound form PC via the PC software online and offline.

*2, Support **0 segment address bits that can be controlled, each address can store **8 groups of voice.

*3, Maximum of **0 section voice that used to edit can be loaded.

*4, 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.

*5, Provided with BUSY signal feedback function.

*6, Chip enter sleep mode automatically without action.

*7, Working voltage: 2.8VDC to 5.5VDC.

*8, Standby current less than *0uA.

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 interface, support for 5 standard MP3function s.

7, With a special function keys, each time to achieve, will play the next sound, and single cycle the current track.

8, Support for RS**2 communication, via the serial port control.

9, Long time stability, strong anti-interference ability.

*0, 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 to re-trigger.

There are *5 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 **9.
