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 I am Chris, the Field Application Engineer from Nuvoton Technology. Today I will introduce the programming and debugging tool, called NuLink-Gang, and NuLink2-Pro. And I will show you in what kind of situation you can utilize the tools. During system development, Nuvoton provides three IDE interfaces: KEIL, IAR, and NuEclipse for user to develop source code. When programming the Chip, Nuvoton provides ICP programming Tool in PC and the debugger Nu-Link2-Pro for users to perform debugging and programming function. User who uses all of the Nuvoton Nu-Maker boards series can develop through the Nu-Link2-Me debugger and programmer; it’s attached to the board. During the mass-production stage, there are 2 modes for programming the target chip. One is online programming and the other is offline programming. At first, in online programming mode, user can use ICP programming Tool and a Nu-Link2-Pro to program a target chip. Besides, if it needs to program several chips at one times, the Nu-Link Command Tool supports program multiple develop board by several Nu-Link2-Pro. Nu-Link2-Pro also supports drag-and-drop Flash programming. User can intuitively complete the programming action. Nu-Link2-Pro In offline programming mode, user can pre-store the programming file in SPI flash, USB flash drive, or SD card. When user wants to program the target chip, pressing the programming button on Nu-Link2-Pro to complete the programming action. If it needs a large number of ICs to be programming, it recommends using the Nu-Link-Gang programmer. Nu-Link-Gang programmer can perform offline programming on four different chips at a time, significantly increasing the programming efficiency. Besides, Nu-Link-Gang programmer can also use the control bus to connect with an automatic programming machine for automatic programming. In the system upgrade, Nu-Link2-Pro also provides five standard communication interfaces such as SPI, I2C, UART, RS485, and CAN for transmission, which is convenient for users to upgrade the system. That’s all for the introduction of Nuvoton’s programming and debugging tool, NuLink-Gang, and NuLink2-Pro. Thank you for watching it. If you want to know more details, please contact us!
