Product Descriptions

The CM6530N is a low power USB 2.0 audio controller builds in 8051 for flexible applications. Accompany with ultra low power codec makes it suitable for low power headset, notebook/mobile docking and microphone applications. The internal 8051 can also be developed to different applications, such as Android Phone Accessories with special functions, such as HID buttons or LED control. The CM6530N 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 I2S support 8~96 KHz sampling rate and 16/24bits resolution. The CM6530N also integrates 512K Byte flash (Including 32KB F/W programming size) and justrequires few passive components to make a finish product. Thus it can save the total BOM cost and PCB area can be smaller.
