Page 4: Overview
NUC505 OVERVIEW NuTiny-SDK-NUC505 is the specific development tool for NuMicro NUC505 series. Users can use NuTiny-SDK-NUC505 to develop and verify the application program easily. NuTiny-SDK-NUC505 includes two portions. One is NuTiny-EVB-NUC505 and the other is Nu- Link-Me. NuTiny-EVB-NUC505 is the evaluation board and Nu-Link-Me is its Debug Adaptor. Thus, users do not need other additional ICE or debug equipment. -
Page 5: Nutiny-Sdk-Nuc505 Introduction
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. -

Page 16: Boot Select
NUC505 Boot Select The power-on setting is used to configure the chip to enter the specified state when the chip is powered up or reset. Since each pin of power on setting has an internal pulled-up resistor when in reset period. If the application needs to set the configuration to “0”, the proper pull-down resistor of 10K-ohm must be added for the corresponding configuration pins. -

NUC505 USB 2.0 High Speed Device The layout rule needs to take USB 2.0 high speed device. 4.6.1 PCB Layer Stack-up For a USB 2.0 high-speed design, recommend to use at least a four-layer PCB for best signal characteristics. The majority of signal traces should run on a single layer, next to this layer should be the GND plane, which is solid with no cuts. -
