Hi everyone, I'm Aaron. The FAE of Nuvoton technology. Today, I'm glad to show you the Nuvoton secure development board, NuMaker-IoT-M2354. The NuMaker-IoT-M2354 is an IoT evaluation board powered by the NuMicro® M2354 series. Before the introduction of NuMaker-IoT-M2354, I will take you to a quick understanding of NuMicro M2354. The M2354 is the latest NuMicro IoT series product which is based on Arm® Cortex®-M23 CPU core technology. The TrustZone® technology based on Armv8-M architecture is a CPU system-wide approach to microcontroller security. The M2354 series carry 1 Mbytes embedded Flash memory and 256 Kbytes SRAM. It's essential for IoT devices with real-time OS requirements. And you can focus on software development without warring about the flash and SRAM resource. The M2354 series is equipped with plenty of peripherals. In addition to providing UART I2C SPI Timer, it also supports the Quad SPI, USB FS OTG, and CAN BUS. Furthermore, to satisfy the IoT device's display development, the M2354 series built-in 8 COM x 40 SEG LCD controller drives up to 320 dots to meet various smart home and IoT appliances. In addition to providing many peripherals, the critical feature of M2354 is supporting many security functions. The secure boot ensures the legality and integrity of the running firmware. The hardware crypto with RSA/ECC/AES/SHA accelerators can help the device connect to the cloud fast and safely. Moreover, the M2354 is equipped with Key Store, which could be used with crypto accelerators to enhance the chip security level. To comply with Arm PSA CertifiedTM Level 3, the M2354 has implemented some countermeasures to protect against non-invasive attacks like side-channel attacks or fault injection attacks. The NuMaker-IoT-M2354 equips a Bosch environmental sensor, BME680, which contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities. After getting data from the sensor, users can send data to the cloud, such as Pelion or AWS, by Mbed OS. Because M2354 supports hardware crypto, the data can be sent more efficiently and safely. The data could be shown on the LCD panel by the LCD library provided in the M2354 BSP. The NuMaker-IoT-M2354 contains a Wi-Fi module and LoRa module for wireless applications. Depending on the data throughput and power consumption, you can choose one of them for your IoT applications. In the LoRa network, each node is not connected but must be connected to the gateway before being linked back to the central host, or data can be transmitted to another node through the central host. For example, if choosing the LoRa module for the cloud development, you could use NUC980 LoRa Gateway for your gateway platform. The NuMaker-IoT-M2354 supports the radio frequency band of the LoRa module on 915MHz and 433MHz, depending on the customer's requirement. In addition to providing the rich peripheral, the NuMaker-IoT-M2354 also equips the Arduino UNO connector and mikroBUS™ connector for flexible applications. Suppose you want to develop other wireless connecting features like 4G-LTE or NB-IoT. In that case, the Nuvoton also provides a UNO-to-PCI adapter board to supports Quectel EC21 4G/LTE and Quectel BG96 NB-IoT modules. The NuMaker-IoT-M2354 also provides multiple power supplies by external power connectors and an ammeter connector that can instantly measure power consumption. In addition, the Nu-link2-Me on the board is a debugger and programmer supporting development on Keil, IAR, GCC, and Mbed IDE. #en #Learning #Basic #Application #Product - Online Purchase Development Tools： ● M2354 Series https://www.nuvoton.com/products/microcontrollers/arm-cortex-m23-mcus/m2354-series/index.html ● NuMaker-LoRa-NUC980 https://www.nuvoton.com/products/iot-solution/lora-platform/ ● NuMaker-M2354 https://direct.nuvoton.com/tw/numaker-m2354 ● Quectel-BG96A https://direct.nuvoton.com/en/quectel-bg96a ● Quectel-EC21A https://direct.nuvoton.com/en/quectel-ec21a - For more information, please visit Nuvoton Technology Website: https://bit.ly/3hVdcmC buy now: https://direct.nuvoton.com/ contact us: SalesSupport@nuvoton.com

Hello, everyone! I'm Chris, Field Application Engineer from Nuvoton Technology. Today, I will introduce you how to design NuMicro M251/ M252 application circuit. Let's start with the power application circuit of M251/M252. The external power should add 10uF and 0.1uF decoupling capacitors, and the capacitor should be placed close to the source of the external power supply. Before the external power enters the VDD/VDDIO/VBAT of the IC, 0.1uF bypass capacitors should be added separately, and the capacitors should be placed close to the IC. Before the external power enters the AVDD, the bead should be connected in series for filtering, and then 1uF, 0.1uF, and 0.01uF bypass capacitors should be added. The bead and capacitors should be placed close to the IC. Before connecting AVDD to VREF, first, connect the bead in series for filtering, and then add 2.2uF, 1uF, and 470pF bypass capacitors. The bead and capacitors should be placed close to the IC. A 1uF bypass capacitor should be added to the internal LDO power supply of the IC, and the capacitor should be placed close to the IC. AVSS and VSS should be connected in series with a bead for filtering. USB_VBUS should be connected in series with a 10-ohm resistor to enhance the ability of USB to resist EFT interference. USB_D+ and USB_D- should be connected in series with 27-ohm resistors for impedance matching. USB_VCC33_CAP needs to add a 1uF bypass capacitor. ICE_DAT and ICE_CLK should be connected to 100K ohm pull-up resistors. The two ends of the high-speed and low-speed crystal oscillators should be connected with an equivalent capacitance of 20pF to VSS. I2C_SCL and I2C_SDA should be connected to 4.7K ohm pull-up resistors. nRESET should be connected to a 10K ohm pull-up resistor and a 10 uF capacitor to VSS. The internal LDO power supply of the IC needs to add a 1 uF bypass capacitor, and the capacitor should be placed close to the IC. In addition, reference circuits for EBI, UART, SPI, and Audio are provided. VDD is connected to 4~32 MHz crystal oscillator, POR33, Power On Control, 5V to 1.5V LDO, IO Cell... and other circuits inside the IC. Among them, GPIO PF.4 to PF.6 and PA.0 to PA.5 output, the high level is equal to VDD. Vbus is connected to the USB 1.1 PHY inside the IC. This 1.5V regulator will provide 1.5V for Digital Logic, SRAM, Flash, POR15, LIRC, MIRC, HIRC... and so on. Vbat is connected to internal 1.5V RTC_LDO and provides 1.5V voltage for RTC, 32.768 kHz crystal oscillator, IO Cell PF.6. VDDIO is connected to some IO cell for use, and the output high level of PA.0 to PA.5 is equal to VDDIO. AVDD is connected to the analog circuit inside the IC, and VREF is the reference voltage of the analog circuit. That's all for the hardware design of the NuMicro M251/M252 series instruction.
