DESCRIPTION

The CM6212 is a USB 2.0 high-speed audio processor that supports USB Audio Device Class 1.0and 2.0.The CM6212 provides standard HDA,I2S TDM and S/PDIF digital audio interface.The maximum outputs are 12 channels with 8 channels TDM,2 channels I2S and 2 channels S/PDIF and the maximum inputs are 12 channels with 8 channels TDM,2 channels I2S and 2 channels S/PDIF.Moreover,the CM6212 supports I2C,SPI and GPIOs to communicate with external device.

The CM6212 is embedded with 8051 MCU and 512KB flash makes it is very flexible to change the USB topology or communicate with external device by changing internal flash code.It also integrates two tricolor PWM LED drivers for status indication.
