High Integrated USB Audio I/O Controller
DESCRIPTION
CM6206 is a highly integrated single chip USB audio
solution. All essential analog modules are
embedded in CM6206, including 8CH DAC and
earphone buffer, 2CH ADC, microphone gain, PLL,
regulator, and USB transceiver. It is very suitable
for high end USB external audio box, USB
multi-channel headphone or USB audio interface
multi-channel speaker set application.
Many features are programmable with external
EEPROM and MCU interface. In addition,
MCU/EEPROM/GPIO control can easily via HID
software interface. Better yet, CM6206 support
stereo MIC, phone jack sense, S/PDIF I/O 48 KHz
sampling rate. Moreover, unique patent driver can
support world‟s first SPEAKER SHIFTER, Karaoke
and Dolby AC-3 real-time encoder functions.

High Integrated USB Audio I/O Controller
In addition to internal registers, users can also access external serial EEPROM by the same way:
Byte [0]
Byte [1]
Byte [2]
Byte [3]
Bit6 = 1 => Access EEPROM
Bit4 = 1 => read Bit4 = 0 => write
DATAL
DATAH
EEPROM address (0 ~ 8‟h3f)
When users intend to read register / EEPROM by “Set Output Report”, the returned data will be transferred
to USB host via HID input report through interrupt pipe. The three bytes of input report data is organized as
below:
Byte [0]
Byte [1]
Byte [2]
MCUIN EEIN
REGIN HEADPON
DATAL from MCU when MCUIN = 1
DATAL from EEPROM when EEIN = 1
DATAL from Register when REGIN = 1
GPIO[8:1] when GPIOC = 1
DATAH from MCU when MCUIN = 1
DATAH from EEPROM when EEIN = 1
www.DataSheet.co.kr
DATAH from Register when REGIN = 1
{4‟d0,GPIO[12:9]} when GPIOC = 1
GPIOC
MUTE
VDN
VUP
Users can distinguish the source of input report by Byte [0]. Byte [1] and Byte [2] consists a word which
may be the content of addressed register or serial EEPROM. It may also be an arbitrary word programmed by
external MCU. In addition, Byte [0] carries the information of HID button status (MUTE, VDN and VUP), and
phone jack sense (HEADPON). VDN / VUP would be 1 when VOLDN / VOLUP button is pressed, and keeps
pressed (VOLDN / VOLUP keeps 0). MUTE would be 1 when MUTEP button is pressed, and would be cleared
to 0 after USB host reads the input report. HEADPON would be 1 when headphone is plugged in (PHONES is
1).
GPIOC will be 1 if any GPIO changed (It only valid when correspond GPIO is in input mode).
Refer to the following tables for the definition of internal registers can be accessed via HID interface:
