USB-C to SMBus bridge for developers

The CP2112 adapter provides a single-chip HID USB to SMBus bridge with a Type-C connector, a 512-byte data buffer and 194-byte OTP ROM for custom device information. It targets engineers building portable controllers, USB dongles or data-logging hardware who need direct I2C access from a host computer.

Replaces discrete USB-I2C dongles

The module integrates the USB transceiver and requires no external crystal or resistor, reducing board space compared with multi-chip solutions. The upgrade is worthwhile when a project needs configurable clock speeds from 48 MHz down to 94 kHz and cross-platform HID library support for Windows, Mac and Linux.

Sustained throughput at 12 megabits per second

The 512-byte buffer handles continuous SMBus traffic without host-side polling gaps, while configurable timeouts and SCL low-limit detection prevent bus lock-up during long captures. LED indicators show read and write activity so developers can verify link health in real time.

Questions about this item

What connector and cable style are required to mount the CP2112 board?

The board uses a USB-C connector and ships with a USB-C cable plus two 7-pin DuPont wire sets for header connections.

Which driver step is often missed when installing the CP2112 on Windows, Mac or Linux?

Install the HID-to-SMBus library API before plugging in the module; without it the device will not enumerate as a bridge.

What on-board storage may need reprogramming if the device address or product ID changes?

The 194-byte one-time programmable ROM stores the customizable product information and slave address.
