The CP2112’s highly integrated USB-to-SMBus bridge controller integrates a USB 2.0 full-speed function controller, USB transceiver oscillator and eight GPIO pins. All customization and configuration options can be selected through a simple GUI-based configurator. Standard HID class devices do not require the development of complex firmware and drivers. The CP2112 device enables fast USB connectivity with minimal development effort.
The CP2112 uses the standard USB HID device class, which is natively supported by most operating systems. A custom driver does not need to be installed for this device. Host applications communicate with the CP2112 through interface libraries provided by Silicon Labs. The interface specification for the CP2112 is also available to enable the development of an API for any operating system that supports HID.
