1 OVERVIEW
NuTiny-SDK-M031TC is the specific development tool for NuMicro® M031 series. User can use
NuTiny-SDK-M031TC to develop and verify the application program easily.
NuTiny-SDK-M031TC includes two portions. One is NuTiny-SDK-M031TC and the other is Nu-Link2-Me. NuTiny-SDK-M031TC is the evaluation board and Nu-Link2-Me is its Debug Adaptor. Thus, user does not need other additional ICE or debug equipment.
The Nuvoton® Arm
® Cortex
®-M0 NuMicro
® M031/M032 series MCU features 1.8 ~ 3.6V operating
voltage, running up to 48 MHz, and provides a good solution for the applications that need low-voltage interface connection operation. This product can be applied to mobile devices, application processor connected peripheral controllers, IoT sensor devices, motor control, industrial control, and consumer devices.
NuMicro® M031/M032 series provide 16 channels of 12-bit ADC with up to 2Msps high conversion
rate and the PWM with 96 MHz high performance interface which sourced from PLL clock for the requirement of precise, high response of volatge or current and mass processing data market.
Besides, NuMicro® M031/M032 series also provide up to 3 sets of UART interface for connecting
more extended modules in the application such as networking or sensor modules.
The functions of NuMicro® M032 series are all based on M031 and enhanced with USB 2.0 full-
speed device feature to provide more possibilities of USB related application.
In breif, the NuMicro® M031/M032 series support the wide voltage range from 1.8V to 3.6V and
temperature ranging from -40°C to 105°C, up to 128 Kbytes of Flash memory, up to 16 Kbytes of
SRAM, up to 8 Kbytes of ISP (In-System Programming) as well as ICP (In-Circuit Programming) and IAP (In-Application Programming) in LQFP64, LQFP48, QFN33, TSSOP28 or TSSOP20 packages. It also supports high immunity of 4KV ESD (HBM)/4.4KV EFT. It is also equipped with plenty of peripherals such as Timers, Watchdog Timers, UART, SPI, I²C, USCI, PDMA, EBI, GPIO, up to 12 channels of 16-bit PWM, up to 16 channels of 12-bit ADC, USB device, low voltage reset, brown-out detector, 96-bit UID (Unique Identification), and 128-bit UCID (Unique Customer Identification).

2 NUTINY-SDK-M031TC INTRODUCTION
NuTiny-SDK-M031TC uses the M031TC1AE as the target microcontroller. Figure 2-1 is NuTiny-SDK-M031TC for M031 series, the left portion is called NuTiny-SDK-M031TC and the right portion is Debug Adaptor called Nu-Link2-Me.
NuTiny-SDK-M031TC is similar to other development boards. Users can use it to develop and verify applications to emulate the real behavior. The on board chip covers M031 series features. The NuTiny-SDK-M031TC can be a real system controller to design user’s target systems.
Nu-Link2-Me is a Debug Adaptor. The Nu-Link2-Me Debug Adaptor connects your PC's USB port to your target system (via Serial Wired Debug Port) and allows you to program and debug embedded programs on the target hardware. The Nu-Link2-Me also supports VCOM function, which gives users more flexibility when debug. To use Nu-Link2-Me Debug adaptor with IAR or Keil, please refer to “Nuvoton NuMicro
® IAR ICE driver user manual “or Nuvoton NuMicro
® Keil
ICE driver user manual” in detail. These two documents will be stored in the local hard disk when the user installs each driver. To use Nu-Link2-Me VCOM function, please refer to Chapter 5.

Downloading and Installing VCOM Driver 5.1
Please connect to Nuvoton NuMicro® website (http://www.nuvoton.com/NuMicro) to download the
“NuMicro® ICP Programming Tool” file. After the ICP Programming Tool driver is downloaded,
please unzip the file and execute the “ICP Programming Tool.exe”. Simply follow the installation and optional steps to install ICP Programming Tool and Nu-Link USB Driver, which included VCOM driver.

Before the NuTiny-SDK-M031TC is connected to the PC, please enable ICESW2 VCOM function by switching on ICESW2. The NuTiny-SDK-M031TC transmits through UART0 to VCOM to send out data. Switch ICESW2 off when using UART0 function without VCOM function.
Setup on the Development Tool 5.3
The example is demonstrated on the Keil μVision® IDE.
5.3.1 Check the Using UART on the Keil μVision® IDE
Please open the project and find system_M031Series.h to check the using UART in DEBUG_PORT, which has to be the same as the using UART in the NuTiny-SDK-M031TC.
