CM6502 / CM6502B

USB Audio Sound Chip

DESCRIPTION

FEATURES

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.



USB 2.0 full-speed compliant

USB Audio Class 1.0 compliant

USB Human Interface Device (HID) Class 1.1

compliant



2 channel DAC for audio output interface

2 channel ADC for audio input interface

Support Digital Mic interface

Build in 48K/44.1KHz and 16bit S/PDIF

transmitter

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.



Build in Equalizer on both playback and recording

paths



Build in AGC on recording path

Support USB suspend/resume/reset functions

Support control, interrupt, bulk, and isochronous

data transfers

CM6502 / CM6502B integrates the Equalizer on

both playback and recording paths to compensate

the frequency response of mic and headphone.



Embedded 1T 8051

Master I2C control interface for external audio

devices or EEPROM access



14 GPIO pins
