STM32F401マイクロコントローラは、STM32F4アクセス･ライン製品群のひとつです。これらのデバイスは、RUNモード時の動的消費電力と処理性能のバランスを最適化するとともに、多数の付加価値機能を小型パッケージ（最小3 x 3mm）に集積しています。
このマイクロコントローラは、84MHzで動作するArm® Cortex®-M4コア（FPU搭載、DSP命令対応）の処理性能と、RUNモードおよびSTOPモード時の低消費電力性能を実現します。
- 処理性能: 84MHz動作、ST独自のART Acceleratorによる、0ウェイト･ステートでのFlashメモリからのコード実行時に、STM32F401は105DMIPS/285CoreMarkのパフォーマンスを実現します。また、DSP命令とFPU（浮動小数点演算ユニット）により、対応可能なアプリケーション範囲を拡大しました。
- 電力効率: ST独自の90nmプロセス、ART Accelerator、およびダイナミック･パワー･スケーリングにより、RUNモードの消費電流を128µA/MHzまで低減しています（Flashメモリからのコード実行時）。STOPモード時の消費電流は9µAまで低減可能です。
- 集積度: STM32F401ポートフォリオでは、128～512KBのFlashメモリと96KBのSRAMを搭載しています。49ピンから100ピンのパッケージまで対応しています。

ビデオ
As part of our embedded online event, we had the pleasure of filming with Reinhard Keil, a Senior Director of Embedded Tools at ARM.
This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course. This is our first STM32 based on Cortex-M33 and its Trustzone and using specific ST security implementation - watch the video to find out more!
The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
STM32F4 Access lines: Entry level and still an F4!
The STM32F4 Access lines are made of STM32F401, STM32F410,STM32F411, STM32F412 and STM32F413/423 devices. They are the entry-level STM32F4 microcontrollers for cost-conscious applications requiring performance, energy efficiency, integration and connectivity.
Access lines, but still with performance and power efficiency:
- Performance up to 100 MHz/ 125 DMIPS with dynamic efficiency down to 89 µA/MHz in Run mode
- ST's Adaptive Real Time (ART) accelerator allowing zero-wait execution from embedded Flash memory
- Batch Acquisition Mode (BAM) for Always-on data collection, even when the core is stopped, and dynamic power scaling
- Low-power digital microphone interface for acquisition of up to 6 microphones
Access lines, but still with high integration and compactness:
- Wide memory choice from 128 Kbytes of Flash memory / 32 Kbytes of RAM up to 1.5 Mbyte of Flash memory / 320 Kbytes of RAM
- Smallest Cortex-M4 based device available in the entire STM32 portfolio, down to 2.553 x 2.579 mm
Access lines, but still with rich connectivity:
- Up to 10 UARTs, USB OTG FS, 3xCANs, and up to 5 SPI/I2S interfaces
- LCD parallel interface, 8080/6800 modes
- Quad-SPI and FMC parallel interfaces supporting a large choice of external memory types
Note : To ease your upgrade from STM32F1 designs to STM32F4 access lines, refer to our application note AN4904.
Access lines, but still with a comprehensive development environment including:
- STM32F412 Discovery kit (32F412GDISCOVERY) combines STM32F412 features with color touchscreen, joystick, stereo MEMS microphones, external memory capabilities, full-speed OTG USB interface and more.
- STM32 Nucleo-144 development board (NUCLEO-F412ZG) with an STM32F412 MCU as well as Arduino, ST Zio and morpho connectivity provides an affordable and flexible way to try out new concepts and build prototypes.
