1Overview

The NuTiny-SDK-NUC123 is a specific development tool for NuMicro™NUC123 series. User can use NuTiny-SDK-

NUC123 to develop and verify the application program easily. The NuTiny-SDK-NUC123 includes two parts: NuTiny-

EVB-NUC123 and Nu-Link-Me. The NuTiny-EVB-NUC123 is the evaluation board and Nu-Link-Me is its Debug Adaptor.

Therefore, user does not need other additional ICE or debug equipment.

2Introduction to NuTiny-SDK-NUC123

The NuTiny-SDK-NUC123 uses the NUC123SD4AN0 as the target microcontroller. Figure 2-1 shows the NuTiny-SDK-

NUC123 for NUC123 series, in which the left portion is called NuTiny-EVB-NUC123 and the right portion is called Nu-

Link-Me.

The NuTiny-EVB-NUC123 is similar to other development boards. User can use it to develop and verify applications to

emulate the real behavior. The on-board chip covers NUC123 series features. The NuTiny-EVB-NUC123 can be a real

system controller to design users’ target systems.

The Nu-Link-Me is a Debug Adaptor, which 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. To use the Nu-Link-Me Debug

Adaptor with IAR or Keil, please refer to the “Nuvoton NuMicro™IAR ICE Driver User Manual“or “Nuvoton NuMicro™Keil

ICE Driver User Manual” for details. The two documents will be stored in the local hard disk when each driver is installed.
