STM32F401微控制器属于STM32 Dynamic Efficiency™器件范围。 这些器件提供了运行模式下动态功耗和处理器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,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的功耗。 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,
    • 4路SPI,速度高达42 Mbit/s,
    • 3路I²C,
    • 1路SDIO,
    • 1个USB 2.0 OTG(全速),
    • 2个全双工I²S,高达 32-bit/192KHz,
    • 速度高达2.4 MSPS的12位ADC,
    • 10个16位或32位定时器,频率高达84 MHz

STM32F4 Access lines: Entry level and still an F4!

The STM32F4 Access lines are made of STM32F401STM32F410,STM32F411STM32F412 andSTM32F413/423 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
