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

Software development for STM32 made easy with STM32Cube™

Software development for STM32 made easy with STM32Cube™

STM32Cube™ is an entirely free tool, providing

STM32CubeMX , a generator of initialization C-code for STM32 MCUs, based on a graphical user interface, and one embedded software library per series of STM32 products, containing the hardware abstraction layer (HAL) for the STM32 peripherals and a set of Middleware (RTOS, USB, TCP/IP, Graphics, …) based on components that are either ST developed or open source

The initialization code and HAL and Middleware library work with all STM32 compilers, the included  project examples are set up for IAR, Keil, and the GCC based Atollic IDE. 

STM32Cube comes with hundreds of application code examples and supports the STM32 F4 series in its first release.
