NUTINY-SDK-NUC029SDE USER MANUAL
1 OVERVIEW
NuTiny-SDK-NUC029SDE is a specific development tool for NuMicro®NUC029SDE. With the
NuTiny-SDK-NUC029SDE, user can develop and verify the application program easily.
The NuTiny-SDK-NUC029SDE includes two portions. One is NuTiny-EVB-NUC029SDE and the
other is Nu-Link-Me. NuTiny-EVB-NUC029SDE is the evaluation board and Nu-Link-Me is its
Debug Adaptor. Thus, user does not need other additional ICE or debug equipment.
The NUC029SDE can bridge the gap and replace the cost equivalent to traditional 8- and 16-bit
microcontroller by 32-bit performance and rich functions. The NUC029SDE supports a wide range
of applications from low-end, price sensitive designs to computing-intensive ones and provides
advanced high-end features in economical products.
The NUC029SDE of NUC029 series is embedded with the Cortex®-M0 core and offers 68 Kbytes
Flash, 4 Kbytes Flash for the ISP, and 8 Kbytes SRAM for industrial control and applications
which need rich communication interfaces or require high performance, high integration.
The NUC029SDE can run up to 50MHz and operate at standard industrial voltage 2.5V ~ 5.5V
with -40℃~ 105℃. It is also equipped with plenty of peripheral devices, such as Timers,
Watchdog Timer (WDT), Window Watchdog Timer (WWDT), UART, SPI, I2C, PWM, GPIO, LIN,
1000 kSPS high speed 12-bit ADC, Low Voltage Reset Controller and Brown-out Detector.
Additionally, the NUC029SDE is equipped with ISP (In-System Programming) and ICP (In-Circuit
Programming) functions, which allow the user to update the program memory without removing
the chip from the actual end product. The NUC029SDE also supports In-Application-Programming
(IAP) function, user switches the code executing without the chip reset after the embedded flash
updated.

2 NUTINY-SDK-NUC029SDE INTRODUCTION
The NuTiny-SDK-NUC029SDE uses the NUC029SDE as the target microcontroller. Figure 2-1 is
NuTiny-SDK-NUC029SDE for the NUC029SDE, the left portion is called NuTiny-EVB-
NUC029SDE and the right portion is Debug Adaptor called Nu-Link-Me.
The NuTiny-EVB-NUC029SDE 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
NUC029SDE features. The NuTiny-EVB-NUC029SDE can be a real system controller to design
user’s target systems.
Nu-Link-Me is a Debug Adaptor. The Nu-Link-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-Link-Me V3.0 also supports VCOM function,
which gives users more flexibility when debugging. To use the Nu-Link-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-Link-Me 3.0 VCOM function, please refer to
Chapter 5.
