NuTiny-SDK-Mini51 User Manual 


1 Overview 

NuTiny-SDK-Mini51 is the specific development tool for NuMicro . Mini51 series. Users can use NuTiny-SDK-Mini51 
to develop and verify the application program easily. 
NuTiny-SDK-Mini51 includes 2 portions. One is NuTiny-EVB-Mini51 and the other is Nu-Link-Me. 
NuTiny-EVB-Mini51 is evaluation board and Nu-Link-Me is its Debug Adaptor. Thus, users do not need additional ICE 
equipment. 


2 NuTiny-SDK-Mini51 introduction 

NuTiny-SDK-Mini51 can support NuMicro . 
Mini51 series. Figure 2-1 is NuTiny-SDK-Mini51 for Mini51 series and the 
left portion is called NuTiny-EVB-Mini51 and the right portion is Debug Adaptor called Nu-Link-Me. 
NuTiny-EVB-Mini51 is similar to other development board. Users can use it to develop and verify applications to 
emulate the real behavior. In fact, the real chip MINI54LAN is mounted on the board. The on board chip covers Mini51 
series features. The NuTiny-EVB-Mini51 can be a real system controller to design user target system. 
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. To use Nu-Link-Me Debug adaptor with Keil or IAR Please refer to ¡°Nuvoton NuMicro . 
IAR ICE driver user 
manual ¡° or Nuvoton NuMicro . 
Keil ICE driver user manual¡± in detail.
