CP2112 debug board USB to I2C Module
The CP2112 debug board USB to I2C Module offers a fully integrated USB-to-SMBus bridge controller that includes a USB 2.0 full-speed function controller, transceiver oscillator, and eight GPIO pins. With a user-friendly GUI-based configurator, all customization and configuration options are easily accessible. Complex firmware and drivers are not necessary for standard HID class devices, making the CP2112 a convenient solution for fast USB connectivity with minimal development effort.
The CP2112 debug board USB to I2C Module utilizes the USB HID device class, which is readily compatible with the majority of operating systems. There is no need to install a specialized driver for this device. Instead, host applications can communicate with the CP2112 using interface libraries from Silicon Labs. Additionally, the interface specification for this device is accessible for creating an API on any operating system that supports HID.
The CP2112 debug board USB to I2C Module SMBus interface is equipped with the essential SDA and SCL signals for smooth SMBus communication. It offers various configurable options such as clock speed, read/write time, retry counter timeout, SCL low time, and a 7-bit device address. Please note that the CP2112 will only acknowledge its designated 7-bit device address and will not respond to any read/write requests. Keep in mind that external pull-up resistors are necessary for both the SCL and SDA signals.
The device boasts a total of eight GPIO signals, all of which can be controlled via USB. These signals offer versatile functionality as they can be configured as either Input or Output, and also have the option of being set as Open-Drain or Push-Pull. Additionally, three of the GPIO signals have the added feature of being able to support alternate functions, such as a customizable clock output that runs at 48 MHz.
The device offers support for varying input/output interface voltages, down to 1.8 V, through its designated VIO pin. Additionally, it also includes a frequency range up to 94 kHz and an option to toggle the TX and RX LEDs.
