 Overview

NuTiny-SDK-NUC122 is the specific development tool for the NuMicro™ NUC122 series. Users can use NuTiny-SDK- NUC122P to develop and verify the application program easily.

NuTiny-SDK-NUC122 includes two portions. One is NuTiny-EVB-122 and the other is Nu-Link-Me. NuTiny-EVB-122 is the evaluation board and Nu-Link-Me is its Debug Adaptor. Thus, users do not need other additional ICE or debug the equipment.

NuTiny-SDK-NUC122 Introduction

NuTiny-SDK-NUC122 uses the NUC122RD2AN as the target microcontroller. Figure 2-1 is NuTiny-SDK-NUC122 for the NUC122 series, the left portion is called NuTiny-EVB-122 and the right portion is Debug Adaptor called Nu-Link-Me. NuTiny-EVB-122 is similar to other development boards. Users can use it to develop and verify applications to emulate the real behavior. The onboard chip covers NUC122 series features. The NuTiny-EVB-122 can be a real system controller to design users’ target systems.
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. To use the NuLink- Me Debug adaptor with IAR or Keil, please refer to the “Nuvoton NuMicro ™ IAR ICE driver user manual“ or “Nuvoton ™ NuMicro Keil ICE driver user manual” for detail. These two documents will be stored in the local hard disk when the user installs each driver.

2.1 NuTiny-SDK-NUC122 Jumper Description

2.1.1 Power Setting

• J1: USB port in NuTiny-EVB-122
• JP1: VCC5 Voltage connecter in NuTiny-EVB-122
• J2: USB port in Nu-Link-Me

POWER Model| J2 USB Port| J1 USB Port| JP1 VCC5| Target MCU Voltage
---|---|---|---|---
Model 1| Connect to PC| X| DC 3.3 V or 5 V
output [1]| DC 3.3 V or 5 V [1]
Model 2| X| Connect to PC| DC 4.8 V or 5 V
output [2]| DC 4.8 V or 5 V [2]
Model 3| X| X| DC 2.5 V ~ 5.5 V input| DC 2.5 V ~ 5.5 V that
decided by JP1 VCC5
input

X: Unused.
Note 1: It is depended on the setting (VCC via connecting to 3.3 V or 5 V via) at the JPR jumper in Nu-Link-Me.
Note 2: It must put a diode device (4.8 V) or make both pins short (5 V) at the D1 in NuTiny-EVB-122.

2.1.2 Debug Connector

• JP3: Connector in target board (NuTiny-EVB-122) for connecting with Nuvoton ICE adaptor (Nu-Link or NuLink-Me)
• JP9: Connector in ICE adaptor (Nu-Link-Me) for connecting with a target board (for example NuTiny-EVB-122)

2.1.3 USB Connector

• J1: Mini USB Connector in NuTiny-EVB-122 for application using
• J2: Mini USB Connector in Nu-Link-Me connected to a PC USB port

2.1.4 Extended Connector

• JP5, JP6, JP7, and JP8: Connect to all chip pins in NuTiny-EVB-122

2.1.5 Reset Button

• SW1: Reset the button to reset the target chip in NuTiny-EVB-122

2.1.6 Power Connector

• JP1: VCC5 connector in NuTiny-EVB-122
• JP2: GND connector in NuTiny-EVB-122

2.2 Pin Assignment for Extended Connector

NuTiny-EVB-122 provides NUC122RD2AN on board and the extended connector for the LQFP-64 pin. Table 2-1 is the pin assignment for NUC122RD2AN.
