超低消費電力マイクロコントローラSTM32L4シリーズ
STは、高い柔軟性により、クラス最高の超低消費電力特性を実現する新しいアーキテクチャを構築しました。STM32L4シリーズは、超低消費電力マイクロコントローラ（マイコン）の効率を比較するために標準化されたEEMBC™ ULPMark®テストにおいて、447ULPMark-CPおよび167ULPMark-PPのスコアを達成しました。STM32L4シリーズは、超低消費電力マイコンとして、きわめて優れた性能を提供します。浮動小数点ユニットとARTアクセラレータ™を備えたArm® Cortex®-M4コアにより、80MHz動作時の性能は100DMIPSに達します。
STM32L4シリーズは、消費電力と処理性能のバランスをとる動的電圧スケーリング、STOPモードでも使用可能な低消費電力ペリフェラル（LP UART、LPタイマ）、セーフティ / セキュリティ機能、優れた数々のペリフェラルに加え、オペアンプ、コンパレータ、LCDドライバ、12bit D/Aコンバータと16bit A/Dコンバータ（ハードウェア･オーバーサンプリング対応）などの高度な低消費電力アナログ･ペリフェラルを搭載しています。
同シリーズにはSTM32L4x1（アクセス･ライン）、STM32L4x2（USBデバイス）、STM32L4x3（USBデバイス、LCD）、STM32L4x5（USB OTG）、STM32L4x6（USB OTG、LCD）など、各種製品ラインが用意されています。
また、他のSTM32マイコンとのピン配置互換性を備えているため、優れた柔軟性を提供すると共に、簡単に設計を移行することができます。
