Introduction The NuMaker M3351KJis a microcontroller platform with comprehensive peripheral integration specially developed by Nuvoton. The NuMaker-M3351KJ is based on the NuMicro® M3331 series MCU with ARM® -Cortex®-M33 core. ### 1.1 MCU specification | | Features | | -- | -- | | MCU | 32-bit Arm CM33 M3351KJCAE | | Operation frequency | 144 MHz | | Embedded Flash size | 1024MB | | SRAM size | 128 kB | ### 1.2 Interface | Interface | | -- | | Arduino UNO | | USB 2.0 Type-C ports | ### 1.3 On-board devices (NuMaker-M3334KI V2.0) | Device | Description | Driver supporting status | | -- | -- | -- | | LED | on-board | Supported | | FSUSB | Device | Supported | ### 1.4 Extended boards | Board | Description | Driver supporting status | | -- | -- | -- | | NUTFT | v1.3 | Supported | ## 2. Supported compiler Support GCC, MDK5 IDE/compilers. More information of these compiler version as following: | IDE/Compiler | Tested version | | ---------- | ------------------------------------ | | MDK5 | 5.40 | | GCC | Arm Embedded Toolchain 10.3-2021.10 (Env 1.3.5 embedded version)| Notice: (1) Please install Nu-Link_Keil_Driver for development. ## 3. Program firmware ### Step 1 At first, you need to configure switch on the NuMaker board. Set the four switches to ‘ON’ position. After the configuration is done, connect the NuMaker board and your computer using the USB Type-C cable. After that, window manager will show a ‘NuMicro MCU’ virtual disk. Finally, you will use this virtual disk to burn firmware. ### Step 2 A simple firmware burning method is that you can drag and drop the binary image file to NuMicro MCU virtual disk or copy the binary file to NuMicro MCU disk to burn firmware. ## 4. Test You can use Tera Term terminate emulator (or other software) to type commands of RTT. All parameters of serial communication are shown in below image. Here, you can find out the corresponding port number of Nuvoton Virtual Com Port in window device manager.
