NuTiny-ML51EBJan 29, 2019 Page 4 of 17 Rev 1.00NUTINY-ML51EB USER MANUAL2 NUTINY-ML51EB INTRODUCTIONNuTiny-ML51EB uses the ML51EB9AE as the target microcontroller. Figure 2.1-1 is NuTiny-ML51EB for the ML51 16K Flash size series, the left portion is called NuTiny-EVB-ML51 and theright portion is Debug Adaptor called Nu-Link-Me.NuTiny-EVB-ML51 is similar to other development boards. User can use it to develop and verifyapplications to emulate the real behavior. The on-board chip covers ML51 series features. TheNuTiny-EVB-ML51 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 tothe user’s target system (via Serial Wired Debug Port) and allows user to program and debugembedded programs on the target hardware. To use Nu-Link-Me Debug adaptor with Keil, pleaserefer to “Nuvoton Nu-Link debug adapter user manual” in detail. This document will be stored inthe local hard disk when user installs each driver. Nu-Link-Me also supports virtual COM portfunction. User can use Nu-Link-Me as a USB to UART virtual COM port, which connects to on-board ML51EB9AE UART0.ICE ControllerExtended ConnectorReset KeyPower LEDUSB ConnectorVDDVSSGPIO LEDML51EB9AEHXT circuitExtended ConnectorVirtual COMEnable SwitchPower SelectConnector5V or 3.3VFigure 2.1-1 NuTiny-ML51EB (PCB Board)Virtual COM Port Switch Description2.1The switch in Nu-Link-Me, SW3, determines that the virtual COM port function is enabled ordisabled. When user turns on all of the positions of switch, the virtual COM port function will beenabled. By using virtual COM port function, user can access the USB device in the same way asit would access a standard COM port to ML51EB9AE UART0 (P3.1 and P3.0) . To use thisfunction, user needs to install “VCOM Driver” at first. User can get “Nuvoton USB driver” fromNuMicroDVD www.nuvoton.com\NuMicroDVD in folder “Software Utilities” or from website:Nu-Link_USB_DriverNuTiny-ML51EB Power Setting and Connector2.22.2.1 Power Setting J1: USB port in Nu-Link-Me J5 and J2: VDD in Voltage connector in NuTiny-ML51EB
