The CM6642 is a low power single chip USB 2.0 High-Speed audio codec built-in MCU for flexible applications. With integrated PWM LED driver and 3-channel ADC/ 2-channel DAC and S/PDIF interface that makes it suitable for headset, headphone, docking, speakers, and microphone applications. The internal MCU can also be developed to a lot of different applications, such as VoIP device, Mobile Phone or Tablet/Slate docking device. The CM6642 is compatible with USB Audio Class 1.0/2.0 and USB 2.0 High-Speed, thus it can plug & play without any additional software installation on major operating systems. The internal DAC support from 44.1~192 KHz and ADC support from44.1~192 KHz sampling rate with 16/24 bits resolution.
The CM6642 also integrates 16K Byte OTP and crystal and just requires few passive components to make a finish product. Thus, it can save the total BOM cost and PCB area can be smaller.
