It is important to note that different models of the M62446 chip may have different pin configurations and functions, which is just a general description. It is recommended that you consult the relevant chip manual or data sheet for the pin function information of the specific model you are using.
The m62446 chip is a high-performance audio digital signal processor with multiple pin functions. Among them, the VCC pin is used for power supply, the GND pin is used for ground connection, and the RESET pin is used to reset the chip. The I2C_SCL and I2C_SDA pins are used to communicate with external devices. Pins IN0 to IN7 are input channels, and pins OUT0 to OUT7 are output channels for the input and output of audio signals. The CLK pin is used to receive the clock signal, and the WS pin is used to receive the frame synchronization signal. For example, the user can connect the external circuit through the pin, input the audio signal into the chip for digital processing, and output the processed audio signal to the external device through the output pin.
