Download the CP2112 USB Bridge Driver here. This is the CP2112  single-chip HID USB to SMBus Master Bridge. The CP2112 devices offer a seamless way to incorporate USB into your applications. By eliminating the need for complicated firmware and lowering development time, they provide a quick and easy solution.

CP2112 USB Bridge Driver


These USB-to-SMBus bridge controllers are highly integrated, needs minimal components and PCB space. In a compact 4 x 4 mm QFN-24 package, they encompass a USB 2.0 full speed function controller, USB transceiver, oscillator, and 8 GPIOs. Customization and settings options are conveniently accessible through a easy to use GUI-based configurator.

With the CP2112 devices, you can establish USB connectivity effortlessly, without the requirement for elaborate firmware or driver development. This simplifies the process and minimizes development efforts. Furthermore, the CP2112 finds suitability in various applications.

Some key options include no firmware development needed, a simple GUI based configurator. Likewise also an integrated USB transceiver that eliminates the need for other resistors. In addition an integrated clock that removes the necessity for a other crystal. Additionally, it is USB 2.0 full speed compatible and functions as a standard HID class device, eliminating the need for a custom driver. The CP2112 also offers 8 GPIOs with configurable options.

Given these options , the CP2112 works with a diverse range of applications, such as USB dongles, medical meters, handheld controllers, point-of-sale products, and data loggers.

Hardware Features

The CP2112 devices offer a range of options that make them highly versatile as well as very convenient to use. Firstly, they serve as a Single-Chip HID USB to SMBus Master Bridge. Likewise it also has an integrated USB transceiver. So there is no need for other resistors or crystals in this setup. As an SMBus master device, it also allows for smooth communication. In addition the GPIO pins can be configured as Input/Output as well as Open-Drain/Push-Pull which provides flexibility.

Furthermore, the CP2112 includes a 512 Byte SMBus data buffer and an integrated 194 Byte One-Time Programmable ROM for storing customizable product information. It also has an on-chip power-on reset circuit and a voltage regulator that outputs at 3.45 V.

As a USB Peripheral Function Controller, the CP2112 is conforming with USB Specification 2.0 and operates at full speed (12 Mbps). It supports USB Suspend states via SUSPEND and /SUSPEND pins. The HID Interface works as a standard USB class device, removing the need for a custom driver. It works on various operating systems, including Windows, Mac, and Linux. Additionally, the interface specification is openly accessible, and there are HID-to-SMBus Libraries available for Windows, Mac, and Linux.

Additional Options

To create quick application development, the CP2112 provides APIs. In terms of SMBus settings options, the clock speed can be changed, and there is a 7-bit Device Address specific to the CP2112. The device only sees this address but does not respond to read and write requests. Read/Write Timeouts, SCL Low Timeout, and Retry Counter Timeout can also  be changed.

The GPIO connection has 8 pins with options that can be changed, which can be used as inputs or open drain and push and pull outputs. You can also change the clock output for other devices, ranging from 48 MHz to 94 kHz. Additionally, the CP2112 allows for LED toggling during SMBus reads and writes.

Regarding the supply voltage, the CP2112 can be self powered within the range of 3.0 to 3.6 V or USB bus powered within the range of 4.0 to 5.25 V. The I/O voltage ranges from 1.8 V to VDD.
