STM32F401微控制器属于STM32 Dynamic Efficiency™器件范围。 这些器件提供了动态功耗（运行模式）和处理性能之间的最佳平衡，同时在3 x 3 mm的小封装内集成了大量的增值特性。
这些MCU提供了工作频率为84 MHz的Cortex®-M4内核（具有浮点单元）的性能，同时还能在运行和停机模式下实现出色的低功耗性能。
- 性能：在84 MHz频率下，从Flash存储器执行时，STM32F401能够提供105 DMIPS/285 CoreMark性能，并且利用意法半导体的ART加速器实现了FLASH零等待状态执行。DSP指令和浮点运算单元扩大了产品的应用范围。
- 功效：该系列产品采用意法半导体90 nm工艺和ART加速器，具有动态功耗调整功能，能够在运行模式和从Flash存储器执行时实现低至128 µA/MHz的电流消耗。 停机模式下，功耗低至9 µA。
- 集成度：STM32F401产品组合具有128至512 KB的Flash存储器和96 KB的SRAM。 封装为49到100引脚。
- 3路USART，速度高达10.5 Mbit/s，

精选 视频
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.

- 利用ST的自适应实时（ART）加速器实现了从内置闪存执行代码零等待状态
- 批采集模式（BAM）始终数据采集开启，即使在内核停止、动态功耗调整时
- 低功耗数字麦克风接口可采集高达6路麦克风
基本型，但仍兼顾高集成度和紧凑性：
- 宽范围的存储器可供选择，从128 KB Flash存储器 / 32 KB RAM至1 MB Flash存储器 / 320 KB RAM
- 具有整个STM32产品线中基于Cortex-M4的最小尺寸器件，低至2.553 x 2.579 mm
基本型，但仍具丰富的连接性：
