· WT588D voice module characteristics

· Module package (with FLASH memory and peripheral circuits) have DIP16, DIP28, chip packaging has DIP18, SSOP20 and LQFP32 form;

· According to external or built-in SPI-Flash's different, play different duration, support 2M ~ 32Mbit of SPI-Flash Memory;

· Embedded DSP audio processor speed, fast processing speed;

· Built 13Bit/DA converter, and 12Bit/PWM output, good sound quality;

· PWM output can directly drive 0.5W/8Ω speakers, push-pull current abundant;

· Support DAC / PWM output of two ways;

· Support for loading WAV audio formats;

· By professional PC operating software, any combination of voice, silence can be inserted, insert the mute does not take up memory capacity, a voice repeated calls have been loaded to multiple addresses;

· USB download mode, support for online download / offline download; WT588D voice chip, even in the case of electricity, will also be able to download the data to the normal SPI-Flash;

· Supports MP3 control mode, control mode button, 3 × 8 key combination control mode, parallel control mode, front-line serial control mode, three-wire serial control mode, and three-wire serial control I / O port expansion output mode;

· Three-wire serial control mode to control the three-wire serial I / O port expansion only to send the data output mode can be switched. Even after switching to the final before switching into a working state after switching mode;

· Arbitrary voice playback status display BUSY signal output;

· Anti-interference, and can be used in industrial applications;

· Section 220 can control the address bits, a single address can be loaded up to 128 bits of voice, the voice within the address bit combination play;

· Support the loaded audio player audition;

· Voice playback stops immediately enter the sleep mode, the chip to a complete stop state;

· 15 kinds of key control mode, any key can be set to any of the control mode;

· Supporting WT588D VoiceChip PC software, the interface is simple, easy to use. The play can greatly limit the functionality WT588D voice chip;

· Simple microcontroller written in a way to get rid of the past, the complicated assembly of thinking;

· A single chip to support multiple external memory;

· Up to 500 segments can be loaded for editing audio;

· Into the quiet time range 10ms ~ 25min;

· Chip reset time 5ms;

· Voltage DC2.8V ~ 5.5V;

· Static sleep current of less than 10uA;

· Support load 6K ~ 22KHz audio sampling rate
