Product Information

Back to top
CM6327A is a highly integrated single chip USB audio solution which comprises more USB audio controller and applications. According to coming more experiences in PC USB Audio peripheral from Vendors’ recommend, Cmedia aggressively design one single chip to let vendors to come more integration products, and increase more revenues.

CM6327A contains high performance mono ADC, and have verious interface like I2C, allowing all kinds of microprocessor or DSP to communicate. Especially in advanced VOIP applications. CM6327A could give you low noise and high quality speech input solution, thus, when it comes to conference or public speech, it would be wonderful choice for you.

Also, CM6327A integrates all essential analog, 1CH ADC, PLL, regulator, USB transceiver, with external EEPROM to customize your own product string, PID and VID , 8/11/16/22/32/44.1/48KHz sampling rate and high quality 16-bit resolution and friendly general purpose inputs and outputs(GPIO) connect the CM6327A to peripheral hardware, like LED, keypads and buttons, there are many features could be programmable with external EEPROM and MCU. External MCU/EEPROM could be easily controlled via HID software interface. 2 LED indicator pins supported provide more flexible behavior with device on / off / operation / recording mute / and controllable flash time.

Product benefit:

• Highly integrated single chip USB microphone solution
• Electrical Noise Immunity via USB Digital Link
• Flexible interface to extent application field
• Provide Microsoft Vista premium logo requirement
• Flexible descriptor option by external EEPROM
