NUTINY-SDK-M031 USER MANUAL

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).

NUTINY-SDK-M031 USER MANUAL

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.
