STM32F401微控制器是STM32 Dynamic Efficiency™设备系列的第一款,整合了多种技术,是动态功耗和执行性能的最佳平衡,同时提高了功能集成度。 STM32F401设计用于需要在小至3 x 3 mm的封装内实现均衡性能、高功效及高嵌入式存储器与外设集成度的医疗、工业和消费类应用。STM32F401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。DSP指令和浮点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系列产品在小至3 x 3 mm的封装内提供了128~512KB Flash、96KB SRAM和49~100个引脚。

  • 3路USART,速度高达10.5 Mbit/s,

STM32F4 Access lines: Entry level and still an F4!

The STM32F4 Access lines are made of STM32F401STM32F410,STM32F411 and STM32F412 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 4 microphones

Access lines, but still with high integration and compactness:

  • Wide memory choice from 128 Kbytes of Flash / 32 Kbytes of RAM up to 1 Mbyte of Flash / 256 Kbytes of RAM
  • Smallest Cortex-M4 based device available in the entire STM32 portfolio, down to 2.553 mm x 2.579 mm

Access lines, but still with rich connectivity:

  • Up to 10 UARTs, USB OTG FS, 2xCANs,  and up to 5 SPI/I2S interfaces
  • LCD parallel interface, 8080/6800 modes
  • QSPI and FMC parallel interfaces supporting a large choice of external memory types
