骅讯USB音频芯片 CM6535 集成512K字节闪存

　　Description and overview

　　The CM6535 is a USB 2.0 audio chip builds in 8051 for flexible applications with Tri-Colors PWM LED driver, two (2)-channel ADC/DACand S/PDIF and 12S interface makes it suitable for headset, notebook/ mobile docking, speaker and microphone applications. The intemal 8051 can also be developed to different applications, such as Microsoft™ Lync/ Skype/VolP device and Android Phone or Tablet/Slate docking device. The CM6535 is compatible with USB Audio Class 1.0 and USB 2.0 full-speed, thus it can plug and play without additional software installation on the major operation systems. The intemal DAC/ADC and 12S support8-96 KHz sampling rate and 16/24bits resolution.

　　The CM6535 integrates the equalizer on both playback and recording paths to compensate the frequency response of microphones and headphones.

　　The CM6535 also integrates 512K Byte flash (Including 32KB F/W programming size) and requires few passive components to make a finish product. Thus, it can save the total BOM cost and PCB area can be smaller.
