DESCRIPTION The CM6635 is a USB 2.0 high speed audio controller that complaints with USB Audio Device Class 2.0. The CM6635 provides standard I2S and S/PDIF digital audio interface. The maximum outputs are 6 channels with 4 channels I2S and 2 channels S/PDIF and the maximum inputs are 6 channels with 4 channels I2S and 2 channels S/PDIF. The first I2S interface can be used to transfer PCM and DSD audio data. Moreover, the CM6635 supports I2C, SPI and GPIOs to communicate with external device. The CM6635 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.
