STM32 F4 series of high-performance MCUs with DSP and FPU instructions

The ARM® Cortex™-M4-based STM32 F4 series is an extension of the industry-leading STM32 portfolio towards even higher performance. Like the STM32 F2 series, these MCUs leverage ST‘s 90 nm NVM technology and ST’s ART Accelerator™ to reach the industry’s highest benchmark scores for Cortex-M-based microcontrollers with up to 225 DMIPS/606 CoreMark executing from Flash memory at 180 MHz operating frequency.

The DSP instructions and the floating point unit enlarge the range of addressable applications. ST’s 90 nm process, ART Accelerator and the dynamic power scaling enables the current consumption in run mode to be as low as 238 μA/MHz.

The STM32 F4 series is the result of a perfect symbiosis of the real-time control capabilities of an MCU and the signal processing performance of a DSP, and thus complements the STM32 portfolio with a new class of devices, digital signal controllers (DSC).
