WT588F02B-8S Flash Sound Playerback Chip

1. 16-bit DSP voice chip, 32MHz internal oscillator;
2. Operating voltage range of 2.2 to 5.5V;
3. 16-bit PWM/DAC output capable of directly driving an 8Ω 0.5W speaker;
4. Supports WAV/MP3 audio file formats (WAV format requirements: sampling rate must not exceed 16KHz, mono; MP3 format requirements: sampling rate must not exceed 24KHz);
5. Customers can replace the voice content inside the chip via MCU or a dedicated downloader;
6. Supports one-wire serial port, two-wire serial port (UART and IIC communication will be available soon);
7. Supports up to 6 MIDI channels playback;
8. Supports over 1000 address segments;
9. Equipped with hardware SPI interface, UART interface, built-in comparator, and other interfaces. Custom functions can be designed for customers;
10. The chip has 220KB of Flash memory;
11. Both the main control program and Flash data can be erased and rewritten;
12. The chip initialization time upon power-up is approximately 200ms;
13. After the chip finishes playing, it enters sleep mode after IO pins (DATA and CLK) maintain a stable level (either high or low) for 1 second.

Selection Notes:
1. The control method of the chip is set during program burning. When ordering custom chips, please inform the sales representative of your application requirements.
2. If you need a chip with lower standby power consumption, please contact our sales representative.
3. If whether dual-byte control is needed is not specified, a total address count less than 224 segments defaults to single-byte encoding, while 224 segments or more defaults to dual-byte encoding.
4. Using 4R speakers or parallel-connected speakers may cause the chip’s PWM to experience latch-up, leading to unplayable audio until the power is cycled again. In severe cases, it may damage the chip.
