マイクロコントローラ & マイクロプロセッサ

All resource types 詳細を非表示


STは、さまざまなペリフェラルが用意された、32bit Arm® Cortex®-Mベース・マイクロコントローラの製品ポートフォリオを幅広く展開しています。これらの製品ポートフォリオにより、アプリケーションのニーズに応じて性能、電力効率、およびセキュリティ機能を柔軟に選択することができます。

また、STM32ファミリに追加されたSTM32マイクロプロセッサ(MPU)は、Arm® Cortex®-AとArm® Cortex<4>®</4>-Mコアを組み合わせたヘテロジニアス・アーキテクチャによって、オープンソースのLinuxやAndroidプラットフォームへのアクセスを可能とし、新たな組込みアプリケーション設計の可能性を開きます。STM32ファミリのマイクロプロセッサは、32bitから64bitプラットフォームへの拡張が可能です。

この柔軟なアーキテクチャにより、デジタル / アナログ・ペリフェラルを各コアに割り当てることができるだけでなく、処理やリアルタイム実行の要件に応じて最適の電力効率を実現します。また、STM32マイコンおよびマイクロプロセッサでは、アプリケーション開発工数の削減に向け、オープンソースのLinuxディストリビューションやSTと3rdパーティ企業が提供する次世代システム・ツールセットを存分に活用できます。

STM32 & STM8 Finder mobile apps

STM8 Finder and STM32 Finder replace the preceding ST MCU Finder mobile app, including new features for a robust and convenient user experience. 

The apps provide access to ST’s complete portfolio of STM8 8-bit microcontrollers, STM32 32-bit Arm® Cortex®-M microcontrollers, and STM32MP15 Cortex-A7 microprocessors, as well as Evaluation Boards, Discovery Kits, and Nucleo development boards. After finding their desired product, users can search related collateral such as documentation, project files, and software.

The apps also enable convenient ordering of devices and development boards and help users connect with developer communities on social platforms such as Facebook™, Twitter™, STM32 YouTube™ channel, and ST Community.
