INTRODUCTION
STM32F4 series of high-performance MCUs with DSP and FPU instructions

The ARM® Cortex®-M4-based STM32F4 series MCUs leverage ST’s NVM technology and ST’s ART Accelerator™ to reach the industry’s highest benchmark scores for Cortex-M-based microcontrollers with up to 225DMIPS 608CoreMark executing from Flash memory at up to 180 MHz operating frequency.

With dynamic power scaling, the current consumption running from Flash ranges from 100 µA/MHz on the STM32F411 up to 260 µA/MHz on the STM32F439.

The STM32F4 series consists of seven compatible product lines of digital signal controllers (DSC), a perfect symbiosis of the real-time control capabilities of an MCU and the signal processing performance of a DSP:
  • STM32F401 – 84 MHz CPU/105 DMIPS, the smallest, cost-effective solution with outstanding power efficiency (Dynamic Efficiency Line)
  • STM32F411 – 100 MHz CPU/125 DMIPS, outstanding power efficiency with large SRAM and new smart DMA optimizing power consumption for data batching (Dynamic Efficiency Line with Batch Acquisition Mode)
  • STM32F446 – 180 MHz/225 DMIPS, up to 512 Kbytes of Flash with dual Quad SPI and SDRAM interfaces
  • STM32F405/415 – 168 MHz CPU/210 DMIPS, up to 1 Mbyte of Flash with advanced connectivity and encryption
  • STM32F407/417 – 168 MHz CPU/210 DMIPS, up to 1 Mbyte of Flash adding Ethernet MAC and camera interface
  • STM32F427/437 – 180 MHz CPU/225 DMIPS, up to 2 Mbytes of dual-bank Flash with SDRAM interface, Chrom-ART Accelerator™, serial audio interface, more performance and lower static power consumption
  • STM32F429/439 – 180 MHz CPU/225 DMIPS, up to 2 Mbytes of dual-bank Flash with SDRAM interface, Chrom-ART Accelerator™ and LCD-TFT controller

What is Cortex M4

The Cortex-M family is an ideal solution for ranges of compatible, easy to use embedded devices such as microcontrollers (MCU) where different cost, power and performance considerations must be made. Each processor delivers an optimal trade-off for a broad embedded application range.



Cortex-M family processors are all binary upwards compatible, enabling software reuse and a seamless progression from one Cortex-M processor to another.



The ARM Cortex™-M4 processor is the latest embedded processor by ARM specifically developed to address digital signal control markets that demand an efficient, easy-to-use blend of control and signal processing capabilities.
The combination of high-efficiency signal processing functionality with the low-power, low cost and ease-of-use benefits of the Cortex-M family of processors is designed to satisfy the emerging category of flexible solutions specifically targeting the motor control, automotive, power management, embedded audio and industrial automation markets.



The Cortex-M4 processor has been designed with a large variety of highly efficient signal processing features applicable to digital signal control markets. The Cortex-M4 processor features extended single-cycle multiply-accumulate (MAC) instructions, optimized SIMD arithmetic, saturating arithmetic instructions and an optional single precision Floating Point Unit (FPU).
These features build upon the innovative technology that characterizes the ARM Cortex-M series processors.
