1 OVERVIEW

NuTiny-SDK-N76E003 is the specific development tool for 8-bit high performance 1T 8051-based microcontroller N76E003 series. User can use NuTiny-SDK-N76E003 to develop and verify the application program easily.

NuTiny-SDK-N76E003 includes two portions. One is NuTiny-EVB-N76E003 and the other is Nu-Link-Me. NuTiny-EVB-N76E003 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 N76E003 series is function compatible with the N76E616 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 N76E003 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 N76E003 benefits to meet a general purpose, home appliances, or motor control system accomplishment.

The N76E003 series can run up to 16 MHz, and operate at a wide voltage range of 2.4V ~ 5.5V and temperature range of -40℃ ~ +105℃. For the N76E003 series, the embedded program flash

size is up to 18 Kbytes, SRAM is 256 bytes, and 768 Bytes of auxiliary RAM (XRAM). The N76E003 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 N76E003 series has many high-performance peripheral functions, such as 16 MHz high-speed internal RC oscillator (trimmed to ±1% when VDD 5.0V, ±2% 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

2C 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-level-priority interrupts capability. All these peripherals have been incorporated into the N76E003 series to reduce component count, board space and system cost.

Additionally, the N76E003 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 N76E003 series also supports In-Application-Programming (IAP) function, user switches the code executing without the chip reset after the embedded flash updated.

2 NUTINY-SDK-N76E003 INTRODUCTION

NuTiny-SDK-N76E003 uses the N76E003AT20 as the target microcontroller. Figure 2-1 is NuTiny-SDK-N76E003 for the N76E003 series, the left portion is called NuTiny-EVB-N76E003 and the right portion is Debug Adaptor called Nu-Link-Me.

NuTiny-EVB-N76E003 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 N76E003 series features. The NuTiny-EVB-N76E003 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 on-board N76E003AT20 UART0.

Figure 2-1 NuTiny-SDK-N76E003 (PCB Board)

Virtual COM Port Switch Description 2.1

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 N76E003AT20 UART0. To use this function, user needs to install “VCOM Driver” at first. User can get “VCOM Driver” from NuMicroDVD www.nuvoton.com\NuMicroDVD in folder “Software Utilities”.
