EFM32WG-DK3850 is an evaluation board that is used for embedded applications that involve the usage of microcontrollers (MCUs) and digital signal processors (DSPs). It is one of the latest boards developed by Silicon Labs, with its own suite of components and hardware that is specifically designed for evaluating both MCUs and DSPs. The main purpose of EFM32WG-DK3850 is to speed up the development of applications and evaluate the performance and design of MCUs and DSPs.

The EFM32WG-DK3850 board contains two different types of microcontrollers. One is the EFM32WG320 MCU that is based on the ARM Cortex-M4F processor. It is a 32-bit MCU that has a maximum operating frequency of 48MHz. The second is the ARM Cortex-M0+ processor. It is a 16-bit MCU that has a maximum operating frequency of 32MHz. In addition, the board also contains a single digital signal processor (DSP) which is the DSC6101, a 16-bit DSP with a maximum operating frequency of 60MHz.

Apart from the microcontrollers and DSP on the board, it also has other components. These include an introduction board, a Debug Adapter, a Breakout Board, USB cables, a prototyping board, a power supply, an LCD touch panel and a range of digital interfaces.

The introduction board is used for demonstrating the features and development kit of the EFM32WG-DK3850. It has an LCD display screen, four push buttons, an RGB LED and two potentiometers to control the volume. The Debug Adapter is used for debugging and programming of the EFM32WG-DK3850 board. It also contains an energy analyzer, a debugger, a bootloader and a serial terminal. The Breakout Board is used for connecting devices and accessing the ports of the board. It has two USB Type-C ports, a micro-USB port, a debug serial port and a general purpose input/output (GPIO) connector.

The USB cables are used for connecting the Debug Adapter, the Breakout Board and the Introduction board to the computer or other devices. The prototyping board is used for experimenting with various hardware components and software. It contains various expansion headers that make it easy to connect other devices. The power supply board is used for providing the board with the necessary power requirements. The LCD Touch Panel is used to display data such as display effects, voltage and current readings and functional tests. The digital interfaces consist of a CAN bus, a USB, an I2C interface and a Flash memory.

The working principle of the board is quite simple. First, the user needs to download the firmware that is needed for the development of the application. Then, the Debug Adapter is connected to the board and the desired application is programmed into the MCU and DSP using the debug software provided with the board. After the application is programmed, it is tested to ensure that it works as expected. Once the application is tested, it can then be deployed to other devices for testing.

The EFM32WG-DK3850 evaluation board is a versatile board that is designed to accelerate the development of embedded applications. It is equipped with multiple types of microcontrollers and a single DSP, and has a wide range of components and hardware for evaluating the performance and design of MCUs and DSPs. It also comes with a set of debug tools that make programming and testing of applications easier. The board is a great tool for developers who want to get a better understanding of the performance of their devices and debug their applications quickly and easily.
