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, 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.

What is the encryption function in the NUC505 series? How to use it? How to use the Disable Cipher function of the ICP tool? Is there any relationship between the Disable Cipher function and MTP? 1480414195818 As the NUC505 series uses SPI Flash, anyone can get code in Flash simply through the SPI interface. Thus, the NUC505 provides an encryption mechanism to protect the SPI Flash internal code to prevent data from being stolen. The NUC505 uses MTP (Multiple-Time Programmable) memory to set the encryption key. The process is shown in Figure 1. The encryption key (or data) is encrypted with the key, and the incorrect key cannot be used to read the correct data from the SPI Flash. When the MTP function is enabled, the CPU accessed data is automatically decoded by the MTP key, so unencrypted code cannot be executed. Note: A total of 15 keys can be re-programmed by MTP In the same chip. Figure 1 MTP Encryption Process The MTP encryption function can be enabled by using the ICP tool.
