3 NUTINY-SDK- USER MANUAL 1 OVERVIEW NuTiny-SDK- is the specific development tool for 8-bit high performance 1T 8051-based microcontroller series. User 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, user does not need other additional ICE or debug equipment. The Nuvoton 1T 8051-based microcontroller series is function compatible with the N76E003 and N76E885 series, the 8-bit high performance 1T 8051-based microcontroller. The instruction set is fully compatible with the standard 80C51 and performance enhanced. The series can bridge the gap and replace the cost equivalent to traditional 4T, 6T and 12T 8-bit microcontroller by 1T 8-bit high performance and rich functions. With high performance CPU core and rich well-designed peripherals, the benefits to meet a general purpose, home appliances, or motor control system accomplishment. The series can run up to 16 MHz, and operate at a wide voltage range of 2.4V ~ 5.5V and temperature range of -40 ~ For the series, the embedded program flash size is up to 18 Kbytes, SRAM is 256 bytes, and 256 Bytes of auxiliary RAM (XRAM). The series also offers size configurable 4K/3K/2K/1K/0K bytes flash of LDROM for the ISP, which provides flexibility to user developed Boot Code. The series has many high-performance peripheral functions, such as MHz high-speed internal RC oscillator (trimmed to ±1% VDD = 5.0 V, TA = 25, ±5% in all conditions), I/O port with up to 18 pins, four 16-bit timers, two full-duplex UARTs ports with frame error detection and automatic address recognition, one SPI interface, one I 2 C interface, up to five enhanced 16-bit PWM output channels, 8 channels 12-bit ADC, Watchdog Timer, Self Wake-up Timer, and a Brown-out Detector. The peripherals are equipped with 18 sources with 4-levelpriority interrupts capability. All these peripherals have been incorporated into the series to reduce component count, board space and system cost. Additionally, the series is equipped with ISP (In-System Programming) and ICP (In- Circuit Programming) functions, which allow the user to update the program memory without removing the chip from the actual end product. The series also supports In-Application- Programming (IAP) function, user switches the code executing without the chip reset after the embedded flash updated. Apr 09, 2017 Page 3 of 16 Rev 1.00

4 NUTINY-SDK- USER MANUAL 2 NUTINY-SDK- INTRODUCTION NuTiny-SDK- uses the AL48 as the target microcontroller. Figure 2-1 is NuTiny-SDK- for the 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. User 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 user s target systems. Nu-Link-Me is a Debug Adaptor. The Nu-Link-Me Debug Adaptor connects your PC's USB port to the user s target system (via Serial Wired Debug Port) and allows user to program and debug embedded programs on the target hardware. To use Nu-Link-Me Debug adaptor with Keil, please refer to Nuvoton Nu-Link debug adapter user manual in detail. This document will be stored in the local hard disk when user installs each driver. Nu-Link-Me also supports virtual COM port function. User can use Nu-Link-Me as a USB to UART virtual COM port, which connects to onboard AT20 UART0. Extended Connector (J12) 3.3V or 5V (JPR1) ICE Controller USB Connector (ICEJ1) Virtual COM Port Function Switch (SW2) Power LED Reset Key (SW1) ICE Controller Target Chip Extended Connector (J11) GND Figure 2-1 NuTiny-SDK- (PCB Board) 2.1 Virtual COM Port Switch Description The switch in Nu-Link-Me, SW3, determines that the virtual COM port function is enabled or disabled. When user turns on all of the positions of switch, the virtual COM port function will be enabled. By using virtual COM port function, user can access the USB device in the same way as it would access a standard COM port to AT20 UART0. To use this function, user needs to install VCOM Driver at first. User can get VCOM Driver from NuMicroDVD in folder Software Utilities. 2.2 NuTiny-SDK- Power Setting and Connector Power Setting J1: USB port in Nu-Link-Me JP7 and JP9: 33 Voltage connector in NuTiny-EVB- Model JPR1 J1USB port JP7 & JP9 33 MCU Voltage Model 1 Select 33 Connect to PC DC 3.3V output DC 3.3V Apr 09, 2017 Page 4 of 16 Rev 1.00
