こんにちは、皆さん。Nuvoton Technologyのフィールドアプリケーションエンジニア、Chrisです。 本日は、M251/M252シリーズのマイクロコントローラーの電源モードについて紹介します。 M251/M252シリーズには複数の電源モードがあり、消費電力、ウェイクアップ時間、動作可能なCPU、および周辺機能によって分類されます。 通常モードでは、CPUが通常通り動作します。アイドルモードでは、CPUクロックのみが無効になり、他の周辺機能は通常通り動作します。 通常モードとアイドルモードは、CPUの動作速度によって、高効率・高速のPL0モードと、低消費電力・低速のPL3モードに分けられます。 低速PL3モードでは、CPUおよび周辺機能のクロックソースは、32.768 kHzまたは38.4 kHzのみ使用可能であることに注意が必要です。 パワーダウンモードには、消費電力に応じて3つの種類があります。 1つ目は「NPD（ノーマルパワーダウンモード）」で、CPUおよび高速周辺機能は停止し、低速周辺機能のみが動作可能です。 2つ目は「FWPD（ファストウェイクアップパワーダウンモード）」で、3つのパワーダウンモードの中で最も速くウェイクアップできますが、消費電力がやや高くなります。 3つ目は「DPD（ディープパワーダウンモード）」で、最も低い消費電力で動作しますが、RAM内のデータを保持できず、ウェイクアップ速度も最も遅くなります。特定の周辺機能またはピンのみでウェイクアップが可能です。 消費電力とウェイクアップ時間の関係について、対応するデータを一覧にしました。 ユーザーは、必要な消費電力とウェイクアップ時間に応じて最適な電源モードを選択できます。 なお、FWPDモードはウェイクアップが最も速い反面、パワーダウンモードの中では最も電力を消費します。 DPDモードは最も消費電力が少ないですが、ウェイクアップ時間が最も長くなります。 また、通常モードは通常の動作モードであるため、ウェイクアップの必要はありません。 アイドルモードの時間単位はパワーダウンモードとは異なり、5サイクルとなります。サイクルの長さは、システムが使用する動作周波数によって決まります。 関連リソースとして、電源管理に関するアプリケーションノートを提供しており、より詳細な操作や説明が記載されています。 詳細を知りたい方は、動画内のURLからダウンロードしてください。 また、BSPパッケージには、さまざまな電源モードのエントリー方法やウェイクアップ方法が含まれていますので、参考にしてください。 以上が電源モードの紹介となります。ご視聴ありがとうございました。 チャンネル登録をしていただくと、さらに多くの動画リソースをご覧いただけます。 詳細情報が必要な場合は、お気軽にお問い合わせください。 #Tool #Training #Learning #Intermediate #ja - For more information, please visit Nuvoton Technology Website: https://bit.ly/3hVdcmC Buy now: https://direct.nuvoton.com/numaker-m251sd Contact us: SalesSupport@nuvoton.com

Hello everyone. Welcome back to Nuvootn’s YouTube channel. This is a reference design of a thermostat made by Nuvoton. The first screen shows the current room temperature of 25 degrees Celsius. You can also set your target temperature through the control panel. The middle switch is the power switch of temperature control. Press the Temperature icon and you can adjust backlight brightness by slide control. Back to the function page, press the Snow icon where you can change the strength of the air conditioner. You can increase or decrease the strength by these up and down arrows or you can press the snow icon for adjustment. Changing the heater, dehumidifier, and fan are the same. The third page is a calendar where you can set the date to book opening and closing the temperature control. What you saw is the reference design introduction. Now let’s talk about the composition of the board. In the middle of the board is a Nuvoton N9H20 main control chip. This main control chip has built-in 32 Mbytes DDR so the board is very clear and the hardware design is easy. At the top side, there is a 1 Gbits NAND Flash for code and pictures storage. At the bottom left there is a connector to the UART control interface. In the middle left area, there is a 5 Voltage (Micro USB) power input. In the upper right corner, there is an RS485 connection. Through this green connector, you can connect to RS485 for fans, air conditioners, and other devices' control. In the lower right corner, there is a chip for power IC and some other parts. The application reference design is concise and powerful. That’s all for the hardware introduction.

Hello! Everyone! I am Nuvoton FAE Tim. Today, I will show you ML56 Capacitive Touch Key PCB Design. First introduce the Touch Sensor Channel Selection. Touch Sensor Channels. ML56 series supports up to 14 touch sensor channels. #Reference Sensor It is recommended to select one reference sensor at touch sensor channel TK7 or TK14. Maximize the distance between the reference sensor and other signals to minimize crosstalk. #Shield Electrodes Put the shield electrode around the touch sensor to get better signal quality and waterproof capability. Recommended to select shield channel at touch TK0, TK4 or clock out pins (P3.2 / P4.6 / P5.7). Next, we will explain the PCB Layout Rules. #Touch Key Shapes Recommended to have a 10 x 10 mm sensor area for good touch key sensitivity. Larger touch sensor electrode work better for thicker cover. #Reference Sensor Recommended to assign the reference key at touch channel TK7 or TK14. Maximize the distance to other signals to minimize crosstalk. Round shape electrode with 1 mm diameter size is enough for normal case. #Ground Plane It is recommended that the traces of the touch key have a good hatched ground plane surround. It is recommended to have hatched ground plane under the touch keys. Hatched ground plane with 6 mil trace and 50 mil grid. #Shield Electrode Put touch keys with shield electrode around which provides the same phase signal around touch keys. Hatched shield electrode with 6 mil trace and 50 mil grid. Shield electrode area needs to keep filled around the touch key in greater than 10 mm width. Finally, explain the Touch Key Cover Thickness. As the cover thickness increases, the touch key sensitivities will decrease. Larger touch key size work better for thicker cover. Recommended touch key diameter size with difference acrylic cover thickness as shown in the table. That's all for today's video, thank you everyone!

Hello everyone, I am Chris, the field application engineer from Nuvoton Technology. Today I will introduce the power modes of the M251/M252 series microcontroller. The M251/M252 series has multiple power modes. The differentiation is based on power consumption, wake-up time, the operable CPU, and peripherals. In normal mode, the CPU is running normally. In Idle mode, only the CPU clock is disabled while other peripherals work as usual. Normal mode and idle mode can be divided into high-efficiency high-speed PL0 mode and low-power low-speed PL3 mode according to CPU operating speed. We should note that in the low-speed PL3 mode, only the clock source of the CPU and peripherals is 32.768 or 38.4 kHz can run. In power-down mode, there are three types according to power consumption. The first is NPD (Normal Power Down Mode). The CPU and high-speed peripherals stop running, and only the low-speed peripherals can work normally. The second is FWPD (Fast Wake Up Power Down Mode), which is the fastest wake-up of the three power-down modes but consumes more power. The third is DPD (Deep Power Down Mode), which consumes the lowest power among the three power-down modes, but the data in the RAM cannot be retained, and the wake-up speed is the slowest. Specific peripherals or pins can only activate the wake-up. For power consumption and wake-up time, we list the corresponding data. Users can choose the most suitable power mode according to the required power consumption and wake-up time. We need to note that FWPD mode will consume more power in the power-down mode because this mode wakes up the fastest. The DPD mode is the least power consumption, but the longest wake-up time.， Also, normal mode is a normal working mode, so there is no need to wake up. The time unit of the idle mode is different from the power-down mode, which is five cycles. The length of a cycle is determined according to the operating frequency used by the system. In the related resources section, we provide application notes for power management, which have more detailed operations and descriptions. If you want to know more, please download it from the URL in the video. There are also various power mode entry and wake-up methods in the BSP package; you can also refer to and use it. That’s all for the power modes introduction. Thank you for watching it. Please subscribe to our channel for more video resources.
