4 NUTINY-SDK- USER MANUAL OVERVIEW NuTiny-SDK- is the specific development tool for NuMicro series. Users can use NuTiny-SDK- to develop and verify the application program easily. NuTiny-SDK- includes two portions. One is NuTiny-EVB- and the other is Nu-Link- Me. NuTiny-EVB- is the evaluation board and Nu-Link-Me is its Debug Adaptor. Thus, users do not need other additional ICE or debug equipment. The ARM Cortex -M0 series can run up to 72 MHz with 28 Kbytes Flash program memory, 6 Kbytes SRAM, and 8 Kbytes Flash loader memory for In- System Programming (ISP) and In Application Program (IAP). The series is equipped with a variety of peripheral, such as GPIOs, Timers, Watchdog Timer (WDT), UART, SPI, I²C, 4 ch x 6-bit PWM,6 ch x 2-bit ADC, Analog Comparator, two sets OPAs, Low Voltage Reset, and Brown-out Detector, and other peripheral.

5 NUTINY-SDK- USER MANUAL 2 NUTINY-SDK- INTRODUCTION NuTiny-SDK- uses the VE3AE as the target microcontroller. Figure 2- is NuTiny- SDK- for series, the left portion is called NuTiny-EVB- and the right portion is Debug Adaptor called Nu-Link-Me. NuTiny-EVB- 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 series features. The NuTiny-EVB- can be a real system controller to design users target systems, supports usb high speed interface, audio headphone out, audio line in and sdcad slot. 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 debug. To use 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.
