STM32F4 系列

带有DSP和FPU指令的STM32 F4系列高性能MCU
 
基于ARM® Cortex™-M4的STM32 F4系列MCU采用了意法半导体的NVM工艺和ART加速器™,在高达180 MHz的工作频率下通过闪存执行时其处理性能达到225 DMIPS/608 CoreMark,这是迄今所有基于Cortex-M内核的微控制器产品所达到的最高基准测试分数。 
 
由于采用了动态功耗调整功能,通过闪存执行时的电流消耗范围为STM32F401的128 µA/MHz到STM32F439的260 µA/MHz。
 
STM32 F4系列包括五条互相兼容的数字信号控制器(DSC)产品线,是MCU实时控制功能与DSP信号处理功能的完美结合体。
 
  • STM32F401 – 84 MHz CPU/105 DMIPS,尺寸最小、成本最低的解决方案,具有卓越的功耗效率 
  • STM32F405/415 – 168 MHz CPU/210 DMIPS,高达1MB、具有先进连接功能和加密功能的Flash存储器
  • STM32F407/417 – 168 MHz CPU/210 DMIPS,高达1MB的闪存(Flash),增加了以太网MAC和照相机接口
  • STM32F427/437 – 180 MHz CPU/225 DMIPS,高达2MB的双区闪存,具有SDRAM接口、Chrom-ART加速器™、串行音频接口,性能更高,静态功耗更低 
  • STM32F429/439 – 180 MHz CPU/225 DMIPS,高达2MB的双区闪存,增加了LCD-TFT控制器
STM32 F4 series - 32-bit MCUs

STM32F411- Dynamic Efficiency MCUs even more efficient

The STM32F411 is a new STM32 Dynamic Efficiency™ microcontroller, bringing power efficiency to a new level.

  • 100 MHz/125 DMIPS 
  • 100 µA/MHz 
  • 512 Kbytes of Flash and 128 Kbytes of RAM
  • Package smaller than 10 mm²
  • Smart connectivity

The devices are equipped with a specific DMA peripheral, which can copy data from communication interfaces or A/D converters to the memory, while the CPU and Flash are off. This allows implementing a batch acquisition mode, with significantly reduced power consumption.
