10, three-wire serial port control mode switch to the three-wire serial port control I / O port expansion output mode only need to send data can be switched. After the switch can still switch to the last working state into the switch after the mode of work;

11, any set to display the voice playback status signal BUSY output mode;

12, strong anti-interference, can be used in industrial areas;

13,220 section can control the address bit, a single address bit can be loaded up to 128 voice, address bit within the combination of voice playback;

14, support for loaded voice playback audition;

15, voice playback to stop immediately into the sleep mode, the chip to completely stop the state;

16,15 kinds of key control mode, any one button can be set to any one control mode;

17, supporting WT588D VoiceChip PC software, the interface is simple, easy to use. Can greatly play the WT588D voice microcontroller functions;

18, a simple way to prepare the microcontroller, get rid of the complicated and complicated compilation of thinking;

19, a single chip supports plug-in multiple memory;

20, can be loaded up to 500 for editing voice;

21, insert the mute time range 10ms ~ 25min;

22, chip reset time 5ms;

23, the working voltage DC2.8V ~ 5.5V;

24, static sleep current less than 10uA;

25, support loading 6K ~ 22KHz sampling rate audio;

26, support 8 chord MIDI playback (this feature to be open).

Function explanation

WT588D voice chip is a powerful repeatable erasure to write the voice microcontroller chip. WT588D let the voice chip is no longer for the control mode and find the right peripheral microcontroller circuit, highly integrated single chip technology is enough to replace the complex peripheral control circuit. Supporting WT588D VoiceChip PC operating software can be free to replace the WT588D voice microcontroller chip any one control mode, the information can be downloaded to the SPI-Flash. Software operation is simple and easy to understand, match the voice combination technology, greatly reducing the voice editing time. Fully support online download, even if the WT588D power case, the same can be downloaded to the associated SPI-Flash download information, to the WT588D voice chip circuit reset, you can update to just download the control mode.

1, support insert silent mode, insert the mute does not take up the capacity of SPI-Flash memory, an address bit can be inserted 10ms ~ 25min mute;

2, MP3 control mode, fully meet the market MP3 playback / pause, stop, on a song, the next song, volume +, volume - and other functions;

3, the key control mode to trigger a flexible way, can be arbitrarily set any button for the pulse can be repeated trigger, the pulse can not be repeated trigger, invalid keys, the level can not be recycled, the level can be maintained, the level of non-retentable, The next song can not cycle, the next song can be recycled, the next song can be loop, volume +, volume -, play / pause, stop, play / stop 15 kinds of trigger mode, up to 10 keys to trigger control Output;

4, 3 × 8 key combination control mode can be triggered by the pulse can be triggered trigger 24 address bit voice, the address can trigger the address bit can be set between 0 ~ 219;

5, parallel port control mode can be 8 I / O port control, only WT588D-32L, WTW-28P;

6, a line of serial control mode can be controlled by the transmitter voice playback, stop, loop and volume size, or directly trigger 0 ~ 219 address bit of any voice, send speed 600us ~ 2000us;

7, three-wire serial port control mode and three-wire serial port control I / O port expansion output mode can be through the code switch, three-wire serial port control mode, can control the voice playback, stop, loop and volume size, or directly trigger 0 ~ 219 Address bit of any voice, three-wire serial port control I / O port expansion output can be extended output 8-bit, in two modes to switch, make the last mode of the last state to maintain the next mode;

8, PWM and DAC output mode, PWM output can directly promote the 0.5W / 8 speaker, DAC output external amplifier, good sound quality.
