WT588F xx A-8S(WT588F 08 A-8S （ A2） built-in 8Mbit Of FLASH；WT588F 04 A-8S built-in 4Mbit FLASH of ) ， WT588F 02 A-8S built-in 2Mbit FLASH of ) ， It is the latest product developed by Shenzhen Weichuang Zhiyin Electronics Co., Ltd 16 bit DSP Voice chip Internal oscillation 32Mhz, 16 bit PWM decoding. Powerful functions make WT588F xx A-8S has become a leader in the voice chip industry. Current WT588F xx A-8S， High sound quality can support storage of up to 680 (8Mbit)/340(4Mbit)/170(2Mbit) Second voice content (if the customer has no requirements for sound quality, it can be stored at most one thousand and two hundred (8Mbit)/600(4Mbit)/300(2Mbit) Seconds of voice content). WT588F xx A-8S is different from traditional OTP chips, and the breakthrough is Customers can replace the internal voice content of the chip through MCU or 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

（ 7) Support up to 6 channels of midi playback;
（ 8) Support more than 1000 addresses;
（ 9) It has hardware SPI interface, UART interface, IIC, built-in comparator and other interfaces. Various functions can be customized for customers.
（ 10) The chip is equipped with 2Mbit/4Mbit/8Mbit Flash.
（ 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, Explain to the salesperson when ordering chips Application requirements.
2. If you need a lower standby power consumption chip, please contact our salesperson.
3. If Not informed whether Single byte required When controlling, Default is double byte Code issuing project.
The minimum reset voltage can be 1.8V. If you need a lower reset voltage, please contact the business.
