STM8 & STM32マイコンの機能安全
STM8およびSTM32ベースの機能安全認証済みシステム
STは、機能安全規格を満足するために必要な開発労力、時間、およびコストの大幅な削減を目的として、組込み型の堅牢なSTM8 MCUとSTM32 MCU、およびMPUをベースとする包括的な一連の認証済み機能安全パッケージを無償で提供します。ユーザに危害を及ぼすリスクが特定されると自動的にトリガされるソフトウェアの機能安全メカニズムは、Industry 4.0、医療機器、車載用機器、および生活家電に存在するさまざまな電子システムと、バッテリ管理システムやドローンなど、安全規制の対象となるすべての新規市場の電子システムに導入されます。
STの複数の認定パートナーは機能安全のエキスパートであり、そのノウハウを、ソフトウェア、ツール、トレーニング、およびその他のサービスによってSTM8とSTM32に展開しています。そのソリューションは、安全要求事項のマッピングからハードウェアとソフトウェアの設計・検証まで、認証フェーズを含むプロジェクトのあらゆる段階で設計者を支援します。
