よくある質問 / Does NUC505 support digital microphone?
https://www.nuvoton.com.cn/support/technical-support/faq/d7df8205-04f1-11ea-b113-05daf7eedf03/
MIC, Digital MIC Does NUC505 support digital microphone? 1515996096499 Yes, the NUC505 Audio CODEC supports digital microphones, but only supports one set of microphone at the same time. The left and right channel data are the same. This is achieved through the digital MIC clock in PA2 (Digital MIC clock in) and PA3 (Digital MIC data out) ports to the digital audio port of internal Audio CODEC. After the digital microphone data is sent to the digital audio port of the internal Audio CODEC via PA3, the internal Audio CODEC will encode the data into the I2S format and send it to the I2S DI of the NUC505. User only needs to connect four pins in the hardware circuit, namely VCC, GND, DMIC IN (PA3) and DMIC CLK (PA2).

NUC505, MTP, Cipher, ICP tool, Off-line ICP, Nu-Link How to use Nu-Link to do encrypted file offline programming for the NUC505 series? 1486028832384 Use the ICP tool to enable the MTP encryption function. The related MTP setting is shown in Figure 1. After the MTP related setting, you can select MTP to encrypt the file. Then, refresh the data area and save the file to obtain an encrypted bin file, as shown in Figure 3. Then, select the Offline Programming Mode option in the programming options and the encrypted bin file will be programed in the Nu-Link memory, as shown in Figure 4. Finally, you can use offline programming to write the encrypted code. For details on NUC505 encryption, refer to the following FAQ and document: -FAQ：http://www.nuvoton.com/support/technical-support/faq/d6fc7487-04f1-11ea-b113-05daf7eedf03/ -ICP Programming Guide：http://www.nuvoton.com/resource-download.jsp?tp_GUID=DA01-NUC505 Figure 1 MTP Programming Setting Figure 2 Select MTP for Programming Figure 3
よくある質問 / How to use RTC function in the NUC505 series?
https://www.nuvoton.com.cn/support/technical-support/faq/d7810e22-04f1-11ea-b113-05daf7eedf03/
NUC505, RTC How to use RTC function in the NUC505 series? 1486030183847 The RTC function in the NUC505 needs to be enabled by RTC_WAKEUP. When the system is powered on, RTC_nRWAKE needs to be grounded so that the RTC function can be enabled. After power on, if the RTC_nRWAKE pin continues low for a period of time (set by the RTC_POWCTL register), the system hardware will automatically shut down. After shut down, the RTC_nRWAKE pin must be powered on or powered down again before the system is restarted. If you do not want the system to shut down, before shut down use the function call RTC_DisableHardwarePowerOff () to disable the RTC power-down function. Execute the RTC demo code in NuTiny-EVB-NUC505_QFN88 as follows: 1. Through ICE, before executing the demo code, press the RTC Wake-up key until the demo code is executed; 2. With the SPI Boot (ICE powered), press the RTC Wake-up key after power on, and then press the Reset key while releasing the Reset and RTC Wake-up keys. 3.

NUC505, LDO_CAP, VDD12 What is the power source supplied to VDD12 in the NUC505 series? 1486033594873 VDD12 in the NUC505 can be powered from an external LDO or internal LDO. External LDO: VDD12 in the NUC505 is connected to an external 1.2V, and LDO_CAP connects a 4.7uF capacitor to ground, as shown in Figure 1. Internal LDO: LDO_CAP in the NUC505 is first connected to the 4.7uF capacitor, and then connected to VDD12, as shown in Figure 2. Figure 1 Figure 2 Note: LDO_CAP: LDO output pin, DC 1.2V. VDD12: I/O power supply pin, DC 1.2V. The NUC505 power distribution diagram is shown below. LDO_CAP needs to be connected to the 4.7uF capacitor first and then ground; if VDD12 needs to be powered internally, LDO_CAP is connected to the 4.7uF capacitor first, and then connected to VDD12.

Can the microphone input with headset control functions (e.g. play/stop, volume increase and decrease) be connected to both the Codec ADC (MIC input) and normal SAR ADC input pins in the NuMicro® NUC505 series? Can a key or which key is pressed be effectively and accurately determined by a specific voltage level? 1480398819667 Connect the microphone input with headset control functions (e.g. play/stop, volume increase and decrease) to both the Codec ADC (MIC input) and normal SAR ADC input pins in the NuMicro® NUC505 series. The following figure shows the application circuit connection. The following table shows the SAR ADC samples that are actually measured when a key or no key is pressed. It is possible to determine whether a key or which key is pressed according to a different SAR ADC value.
