DESCRIPTION
CM6502 / CM6502B are a USB 2.0 audio chip builds in 8051 for flexible applications. With internal 2-channel ADC and DAC and S/PDIF interface makes it suits for Headset, Docking, Speaker and Mic applications. The internal 8051 can be also developed to a lot of different applications, such as Lync device, iDevice docking or even Android Phone or Tablet/Slate docking device.
CM6502 / CM6502B is compatible with USB audio Class 1.0, thus it can plug & play without additional software installation on the major operation systems. The internal DAC/ADC and S/PDIF out interface support 48K/44.1KHz sampling rate and 16bit resolution.
CM6502 / CM6502B integrates the Equalizer on both playback and recording paths to compensate the frequency response of mic and headphone.
