• Manufacturer Part Number: CM106-F+
• Description: USB Audio I/O Controller
• Manufacturer: CMEDIA [C-Media Electronics]

CM106F+/L+ can communicate with external MCU via two-wire serial interface and act as a
slave device. By this way, MCU can read four bytes from and write two bytes to USB host
through CM106.When MCU writes two bytes to CM106F+/L+, the data will be transferred to USB
host via HID ‘Input Report’. USB host will keep polling HID report every 32ms.
CM106F+/L+ can also transfer four bytes from USB host to MCU. This is accomplished by a ‘Set
Output Report’ HID request issued by USB host. CM106F+/L+ will then assert MINT to inform
