超低消費電力マイクロコントローラSTM32L1シリーズ
STのArm® Cortex®-M3ベースのSTM32L1シリーズは、ST独自の超低リーク・プロセス技術と革新的な自律型動的電圧スケーリングおよび5種類の低消費電力モードを使用して、あらゆるアプリケーションに適合する前例のない柔軟性を備えたプラットフォームを提供します。STM32L1シリーズは、性能を損なうことなく、超低消費電力コンセプトを拡張します。
STM32L0やSTM8Lと同様に、STM32L1は動的電圧スケーリング、超低消費電力クロック発振器、LCDインタフェース、コンパレータ、D/Aコンバータ、ハードウェア暗号化エンジンを提供します。
STM32L1シリーズは、超低消費電力マイクロコントローラであると同時に、機能、メモリ容量、およびパッケージのピン数に幅広い選択肢を用意しています。超低消費電力と優れたパフォーマンスを兼ね備えたポートフォリオには、32 ~ 512KBのFlashメモリ(および最大80KBのSRAMと16KBのEEPROM)、48 ~ 144ピンのパッケージが含まれます。
この画期的なアーキテクチャ(電圧スケーリング、超低消費電力MSIオシレータ)により、極めて限られた電源条件でも高性能な設計が可能になります。USB、LCDインタフェース、オペアンプ、コンパレータ、高速オン/オフ・モードを備えたA/Dコンバータ、D/Aコンバータ、静電容量方式タッチキー機能、AESなどの多彩な内蔵ペリフェラルにより、STM32L1シリーズはユーザのあらゆる要求に適合する拡張可能なプラットフォームです。
このシリーズには、STM32L100バリュー・ライン、STM32L151、STM32L152(LCD)、およびSTM32L162(LCDとAES-128)の4つの製品ラインが用意されています。
移行を容易にし、必要な柔軟性をあらゆる面で提供するために、STM32L1は各種STM32Fシリーズとピン互換であり、STM32エコシステムへの扉を開きます。
