ST: STM32 F4

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 microncontrollers with 210 DMIPS at 168 MHz operating frequency.

The DSP instructions and the floating point unit enlarge the range of addressable applications.

The STM32 F4 series is the result of a perfect symbiose 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).

The STM32 F4 series remains pin-to-pin and software compatible with the STM32 F2 series and features more SRAM, peripheral improvements such as full duplex I²S, improved RTC and faster ADCs.
