● General
WT588F02B-8S is a 16 bit DSP newly developed by Shenzhen Weichuang Zhiyin Electronics Co., Ltd Voice chip Internal oscillation 32Mhz, 16 bit PWM decoding. The powerful functions make WT588F02B-8S a leader in the voice chip industry. At present, the WT588F02B-8S can store voice content of 170 seconds at most with high audio quality (if the customer has no requirements for audio quality, it can store voice content of 320 seconds at most). WT588F02B-8S is different from the traditional OTP chip. The biggest breakthrough is that customers can change the internal voice content of the chip online through the matching downloader; And the chip has built-in hardware SPI, UART, IIC, comparator and other resources, which can customize various personalized functional products for customers.
● Function description
（ 1) 16 bit DSP voice chip, 32Mhz internal oscillation;

（ 7) Support up to 6 channels of midi playback;
（ 8) Support more than 1000 addresses;
（ 9) It has hardware SPI interface, UART interface, built-in comparator and other interfaces. Various functions can be customized for customers.
（ 10) 220KB Flash is built into the chip.
（ 11) The chip master program and Flash data can be erased and then burned.
（ 12) The chip power on initialization time is about 200ms
（ 13) After the chip plays, and the I/O port (DATA and CLK) keeps the level stable (both high and low levels are available) for 1s, the chip goes into sleep
Note for model selection:
1. The control mode of the chip has been set when the program is written, When ordering chips, you need to explain the application requirements with the salesperson 。
2. If you need a lower standby power consumption chip, please contact our salesperson.
3. If Not informed Need Double byte When controlling, the total number of addresses is less than Section 224 default by Single byte Send code, and the segment greater than or equal to 224 is double byte send code.
