1 Overview The NuTiny-SDK-NUC220 is a specific development tool for the NuMicro NUC220 series users to develop and verify the application program easily. The NuTiny-SDK- NUC220 includes two portions: NuTiny-EVB-NUC220 (an evaluation board) and Nu- Link-Me (its Debug Adaptor), such that users do not need additional ICE or debug equipment. Jan. 23, 2013 3 of 18 Rev. 1.00

2 Introduction to NuTiny-SDK-NUC220 The NuTiny-SDK-NUC220 uses the NUC220VE3AN as the target microcontroller. Figure 2-1 shows the NuTiny-SDK-NUC220 for NUC220 series, in which the left portion is called NuTiny-EVB-NUC220 and the right portion is called Nu-Link-Me. The NuTiny-EVB-NUC220 is similar to other development boards, by which users can develop and verify applications to emulate the real behavior. The on board chip covers NUC220 series features. The NuTiny-EVB-NUC220 can be a real system controller to design the users target systems. The Nu-Link-Me is a Debug Adaptor, which connects your PC's USB port to a 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 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 is installed. Figure 2-1 NuTiny-SDK-NUC220 PCB Board Jan. 23, 2013 4 of 18 Rev. 1.00
