Module features:
1. Module packages (with FLASH memory and peripheral circuits) include DIP16, DIP28, and chip packages include DIP18, SSOP20 and LQFP32;
2. Depending on the plug-in or built-in SPI-Flash, the playback time is different, and it supports 2M~32Mbit SPI-Flash memory;
3. Built-in DSP high-speed audio processor, fast processing speed;
4. Built-in 13Bit/DA converter and 12Bit/PWM output, good sound quality;
?PWM output can directly drive 0.5W/8Ω speakers, with plenty of push-pull current;
5. Support DAC/PWM two output modes;
6. Support loading WAV audio format;
7. Voices can be combined at will through professional host computer operating software. Mute can be inserted. The inserted mute does not occupy the capacity of the memory. A loaded voice can be repeatedly called to multiple addresses;
8. USB download mode, support online download/offline download; even when the WT588D voice chip is powered on, the data can be downloaded to SPI-Flash normally;
9. Support MP3 control mode, key control mode, 3×8 key combination control mode, parallel port control mode, one-line serial control mode, three-wire serial control mode, and three-wire serial control I/O port expansion output mode;
10. The three-wire serial port control mode is switched to the three-wire serial port control I/O port expansion output mode, which can be switched only by sending data. After switching, the last working state before switching can still be brought into the mode after switching;
11. Arbitrarily set the BUSY output mode of the voice playback status signal;
12. Strong anti-interference, can be used in industrial fields;
13. 220 segments of address bits can be controlled, a single address bit can load up to 128 segments of voice, and the voice combination in the address bit is played;
14. Support to play and listen to the loaded voice;
15. The voice playback stops and immediately enters sleep mode, and the chip turns to a complete stop state;
16. 15 button control modes, any button can be set to any control mode;
17. Supporting WT588D VoiceChip host computer software, with simple interface and convenient use. Can maximize the functions of the WT588D voice microcontroller;
18. Simple single-chip programming method, get rid of the complicated and cumbersome assembly thinking in the past;
19. A single chip supports multiple external memories;
20. Up to 500 voices for editing can be loaded;
21. The range of inserted mute time is 10ms~25min;
22. The chip reset time is 5ms;
23. Working voltage DC2.8V~5.5V;
24. The static sleep current is less than 10uA;
25. Support loading audio with sampling rate of 6K~22KHz;
26. Support 8 chord MIDI playback (this function is to be opened).
