Features
WT2003H4-16S is a powerful and high-quality voice chip that uses a high-performance 32-bit processor with a maximum frequency of 120MHz. It has the characteristics of low cost, low power consumption, high reliability, and strong versatility. It can have a built-in voice capacity of 100 seconds\\350 seconds. Flexible control mode: support standard asynchronous serial communication (UART). Support SPI-Flash and U disk as storage. With file index play, interstitial play, single loop,
all track loop, random play and other functions. The volume is adjustable in 32 levels, and the maximum can support external 128Mbit Flash and 32G U disk.
* Support SPI-Flash、U disk * Suport FAT，FAT32 file system
* Control mode: standard UART communication interface, support DMA and flow control, the default baud rate is 9600 It is not played by default after power-on; with BUSY status indication, it is high level when BUSY is playing
* The external Flash can be connected to the computer through the USB interface of the chip to view or modify its content, and directly download the voice in the computer to the removable drive letter simulated by Flash (simulated U disk) (XP system, WIN7 system, WIN10 system)
* Support switching the audio output mode, the sample defaults to SPK output, if you need DAC output, please refer to the audio output switching instruction (0xB6)
* Support voice high-quality audio format, (8kbps~320kbps) beautiful sound * Support up to 128Mbit Flash and 32G U disk * Built-in 0.5W Class D power amplifier
* The volume is adjustable, the volume level is 32 levels
* Two 16-bit asynchronous divider timers
* Digital audio streaming, IIS supports host and slave modes
* One ICC controller
* An infrared remote control decoder
* 16 bit high precision ADC
* 16 bit high precision DAC
* High-power IO drive capability, up to 64mA can be directly driven
* High-power IO drive capability, up to 64mA can be directly driven
* When using a single chip (using built-in capacity), the built-in voice needs to be written before leaving the factory
