Support loading WAV audio formats;? support loading 6K ~ 22KHz audio sampling rate;? support for the loaded speech broadcast listen;? by professional PC operating software , random combination of voice, insert mute, mute inserted not take up memory capacity, a loaded voice repeated calls to multiple addresses;? 220 can control the segment address bits, a single address bits can load up to 128 segments voice, address bits Voice combination play inside;? Load up to 500 segments for editing voice;? USB download way, support online download / offline download; even in the case of WT588D voice chip energized, the same can not download data to the SPI -Flash;? chip reset time 5ms;? Support MP3 control mode, the key control mode, 3 × 8 key combination control mode, parallel control mode, the front-line serial control mode, three-wire serial control mode and three-wire serial control control port expansion output mode; ? three-wire serial control mode switch to three line serial control port expansion output mode simply send data can be switched. After the switch can still work the last state before switching into work mode after switching;? Arbitrarily set the display mode voice playback state BUSY output signal;? Strong anti-interference, can be applied in the industrial field;? 220 segments can be control address bits, a single address bits can be loaded up to 128 segments of voice, voice broadcast address bits within portfolio;? voice playback is stopped immediately goes into sleep mode, the chip into a complete stop;? 15 kinds of key control mode, any one of the buttons can be set up given any control mode;? WT588D VoiceChip supporting PC software, the interface is simple and easy to use. Can greatly limit the functionality WT588D play voice microcontroller;? A simple microcontroller written in a way to get rid of the past, complicated compilation of thinking;? A single chip to support multiple external memory;? Inserted mute time 10ms ~ 25min;? Operating voltage DC2.8V ~ 5.5V;? quiescent current of less than dormant 10uA;? Supports 8 polyphonic MIDI playback (this feature is to be open). 2, WT588D voice chip functions overview WT588D voice chip is a powerful voice can be programmed to repeat erase single chip. WT588D let voice chip for control mode and no longer find suitable peripheral microcontroller circuit, highly integrated single-chip technology sufficient to replace the complex peripheral control circuits. Supporting WT588D VoiceChip PC operating software can easily replace any voice control mode WT588D microcontroller chip, to download information to the SPI-Flash can be. Software operation simple and easy to understand, matching the voice combination technology, greatly reducing the time to voice editing. Full support for online download, even if the case WT588D energized, as you can by downloading the associated SPI-Flash to download information to WT588D voice chip reset circuit look, you can update to just download came in the control mode. Supports insert silent mode, insert mute does not take SPI-Flash memory capacity, an address bit can be inserted mute 10ms ~ 25min; in MP3 control mode, completely on the market to meet the MP3 play / pause, stop, previous track, next Song, Volume +, Volume - and other functions; keystrokes control mode triggered flexible way, are free to set any buttons for pulse can repeat trigger pulse can not repeat trigger, invalid buttons, level remains non-recyclable, can be recycled to maintain the level of electricity level of non-recyclable maintain, on a non-circulating, in a non-circulating, on a recyclable, under a recyclable, Volume +, Volume -, Play / Pause, Stop, Play / Stop and other 15 kinds of trigger Up to 10 keys can be used to trigger control output; 3 × 8 key combination under control modes can be repeated trigger pulse triggered 24 address bits of voice, voice triggered address bits can be set between 0 to 219; parallel control mode Available 8 control port is limited to WT588D-32L, WTW-28P; line serial control mode can be controlled by voice hair code end play, stop, loop playback and volume size, or directly trigger any voice from 0 to 219-bit address hair yards speed 600us ~ 2000us; between three-wire serial control mode and three-wire serial control control port expansion output mode can be switched by sending a code, under the three-wire serial control mode, can control the voice play, stop, loop playback and volume size, or direct trigger 0 ~ 219 address bits of any speech, three-wire serial control port expansion control output can be extended output 8, switch between the two modes, make a model of a state last kept into the next mode. WT588D voice chip and module details PWM and DAC output, PWM output can be directly promote 0.5W / 8Ω speakers, DAC output external amplifier, good sound quality. Wide range of applications, almost all of the voice can relate to places such as the stops, alarm, reminder, alarm clock places, machine learning, intelligent appliances, therapeutic equipment, electronic toys, telecommunications, parking sensors and a variety of automatic control devices , to achieve the requirements of the industrial application of the process.
