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。

Getting started with STM32L4

- Purchase a 32-pin, 64-pin or 144-pin Nucleo board, Discovery kit or Evaluation kit for STM32L4 MCUs.
Download the STM32CubeL4 embedded software package containing the HAL, LL (low-layer) APIs, and middleware. Then install ST’s STM32CubeMX graphical software configuration tool that supports pinout configuration, code generation and a power consumption calculator. Start with one of the many examples provided or build your own project.
