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 NuLink-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.
®
®
The NuMicro NUC505 series 32-bit microcontrollers are embedded with ARM Cortex -M4F
core for consumer and industrial applications which need high computing power and rich
communication interfaces.
®
®
The ARM Cortex -M4F core within NuMicro NUC505 series can run up to 100 MHz and
support DSP extensions and Floating Point Unit (FPU) function. The NuMicro NUC505 series
supports 128 Kbytes embedded SRAM with zero-wait state and 2 Mbytes embedded SPI Flash
memory, and is equipped with plenty of high performance peripheral devices, such as 24-bit
Audio CODEC, USB2.0 High-speed Device, USB2.0 Full-speed Host, and other peripheral.

NUTINY-SDK-NUC505 INTRODUCTION
NuTiny-SDK-NUC505 uses the NUC505Y013Y as the target microcontroller. Figure 2-1 is
NuTiny-SDK-NUC505 for NUC505 series, the left portion is called NuTiny-EVB-NUC505 and the
right portion is Debug Adaptor called Nu-Link-Me.
NuTiny-EVB-NUC505 is similar to other development boards. Users can use it to develop and
verify applications to emulate the real behavior. The on board chip covers NUC505 series
features. The NuTiny-EVB-NUC505 can be a real system controller to design users’ target
systems, supports usb high speed interface, audio headphone out, audio line in and sdcad slot.
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 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.

HXT:High Speed Crystal(12 Mhz)
For C24 and C25 is recommended to use high-quality ceramic capacitors in the 5pF~20pF range,
designed for high-frequency applications and selected to meet the requirements of the crystal or
resonator. C24 and C25 are usually the same value. The crystal manufacturer typically specifies a
load capacitance that is the series combination of C24 and C25. The PCB and MCU pin
capacitances must be included when sizing C24 and C25 (20pF can be used as a rough
estimation of the combined pin and board capacitance), external resister need 1 MHz
4.3.2
LXT: Low Speed Crystal(32.768 Khz)
For C21 and C22 is recommended to use high-quality ceramic capacitors in the 5~33 pF range,
designed for RTC applications and selected to meet the requirements of the crystal or resonator,
external resister need 10Mhz
Applications requiring oscillators on NUC505 series MCUs must take PCB layout into
consideration. The oscillators on NUC505 series MCUs consume very little current, and it
sometimes makes the oscillator circuit sensitive to neighboring circuits. The following lists some
PCB design guidelines:

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 10KOhm must be added for the corresponding configuration pins.

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. Avoid running signal traces across a split in the
ground or power plane. Minimizing the number of signal vias reduces EMI by reducing inductance
at high frequencies.
If you attempt a two-layer board, you will need to reduce the thickness of the PCB along with
increasing separation of traces and increased trace widths to maintain the impedance match of
the D+ and D- data lines. To put things in perspective, what would be D+ and D- lines at 6mil
trace and 6mil space in a four layer board become 18mils wide with 8mil spacing in a two-layer
board.
4.6.2
Through Hole for D+ and D-
For the two-layer or multi-layer of PCB, when the signals of D+ and D- need to be through another
layer, in which the resistively of through hole should be concerned. To lower the resistively issue
for the sensitivity case, the two-via or multi-via should be adapted, as shown in the following
figure.

Signal Trace for D+ and D-
To avoid the trace effect signal for the eye diagram, the trace length should be almost the same of
D+ and D-. Then, the characteristic impedance should be a symmetrical path for the differential
end of the USB port. The characteristic impedance should be 90  for USB 2.0 high speed. For
reducing the trace length, the USB terminal should be as close as the USB port of NUC505 series
MCUs.

Others PCB design guideline for USB 2.0-

Control differential impedance on USB traces (90 Ohms)

Isolate USB traces from other circuitry and signals

Keep bulk capacitors for down-stream port’s VBUS power close to connectors

Isolate crystal and oscillator

Isolate VRES resistor and keep short traces


Power
The ADAC_VDD33, ADAC_HPVDD33, RTC_VDD33 need stable power in user application, 0
ohm can direct short in user application.

The VDD pins must be connected to 3.3V with external decoupling capacitors. (a 0.1uF
capacitor for each VDD pin and a 1uF capacitor for the whole chip).

The AVDD pin recommend be connected to two external decoupling capacitors
(0.1uF+10nF).
To keep the analog power stable, additional precautions need to be taken to filter analog noise.
The following are two suggestions for the board level designing:

AVDD can be connected to VDD through a ferrite bead.
The RTC _VDD33 pin also powers the RTC unit, allowing the RTC to operate even when the
main digital supply (VDD) is turned off. If no external battery is used in the application, it is highly
recommended to connect VBAT pin to VDD with a 0.1uF external decoupling capacitor.

The device provides left and right channel line-in inputs. The inputs are high impedance, low
capacitance AC coupled.
All inputs include independent PGA (programmable gain amplifier) and mute function. Passive
RF and active Anti-Alias filters are also incorporated within the line inputs to prevent high
frequencies aliasing into the audio band or otherwise degrading performance.
The inputs are biased internally through the operational amplifier to Bais. The external
components required to complete the line input application are shown in the following figure.
